Abstract

Objectives

Although inherited retinal disorders (IRDs) related to the gene encoding the retinal pigment epithelium 65kD protein (RPE65) significantly impact the vision-related quality of life (VRQoL), their emotional and social aspects remain poorly investigated in Italy. Narrative Medicine (NM) reveals the more intimate aspects of the illness experience, providing insights into clinical practice.

Design and setting

This NM project was conducted in Italy between July and December 2020 and involved five eye clinics specialised in IRDs. Illness plots and parallel charts, together with a sociodemographic survey, were collected through the project’s website; remote in-depth interviews were also conducted. Narratives and interviews were analysed through NVivo software and interpretive coding.

Participants

3 paediatric and 5 adult patients and eight caregivers participated in the project; 11 retinologists globally wrote 27 parallel charts; 5 professionals from hospital-based multidisciplinary teams and one patient association member were interviewed.

Results

Findings confirmed that RPE65-related IRDs impact VRQoL in terms of activities and mobility limitations. The emotional aspects emerged as crucial in the clinical encounter and as informative on IRD management challenges and real-life experiences, while psychological support was addressed as critical from clinical diagnosis throughout the care pathway for both patients and caregivers; the need for an IRDs ‘culture’ emerged to acknowledge these conditions, and therefore, promoting diversity within society.

Conclusions

The project was the first effort to investigate the impact of RPE65-related IRDs on the illness experience through NM, concomitantly addressing the perspectives of paediatric and adult patients, caregivers and healthcare professionals and provided preliminary insights for the knowledge of RPE65-related IRDs and the clinical practice.

STRENGTHS AND LIMITATIONS OF THIS STUDY.

  • Inclusion of paediatric patients’ perspectives.

  • Integration of patients’ and caregivers’ perspectives to that of retinologists and hospital-based multidisciplinary professionals.

  • Participants did not equally represent the geographical areas of Italy.

  • Restrictions due to Sars-CoV-2 pandemic impacted the number of patients visiting the clinics, so involved healthcare professionals had to engage them virtually.

  • Patients and caregivers participated in the project on a voluntary basis, and SARS-CoV-2 pandemic could have created a bias on the motivation to join the research.

Introduction

Affecting about 1 in 2–3000 people globally,1 inherited retinal disorders (IRDs) constitute a group of clinically and genetically heterogeneous degenerative conditions in which gene mutations affect the proteins necessary to functional vision.2 A progressive loss of photoreceptor cells and an impairment for visual function characterise the IRDs related to mutations involving the gene encoding the retinal pigment epithelium 65kD protein (RPE65) and gradually lead to an irreversible visual decline,3 and potentially to blindness4; Leber congenital amaurosis and retinitis pigmentosa (RP) represent the most common forms.5 6

Age of onset ranges from early childhood to middle age; visual impairment at low light levels, night blindness and nystagmus are the early symptoms, followed by an increasing deterioration of visual acuity and peripheral vision.7 While gene therapy represents a promising scenario for treating these conditions,3 8 IRDs management has been mainly support-oriented and focused on monitoring, counselling and education.3

RPE65-related IRDs significantly impact patients in daily activities,9 with implications for their sense of identity10 and autonomy management11; previous studies associate visual impairment with lower social engaging ability,12 self-confidence and vision-related quality of life (VRQoL),13 as well as with higher levels of depression.14 15

Against this backdrop, other studies and reviews16 17 suggest that a holistic and multidisciplinary approach—also addressing IRDs emotional and social aspects—is crucial to support patients and their caregivers.

The WHO has acknowledged narrative research as informative to address the illness experience18 in leading clinical practice19; a keen focus on narratives resulted in better patient care also in clinical genetics practice.20 As described in similar studies,21 Narrative Medicine (NM) is based on illness narratives22 and aims to integrate the disease-centred approach, related to the biomedical sphere, with the illness-centred and sickness-centred approaches, focusing on the individual and social experience of a condition,23 respectively. NM addresses the possible interventions on a specific disorder by integrating the perspectives of all the actors involved in the care pathway,24 and its findings have been increasingly used to improve the quality of care in clinical practice.25 26

The NM project ‘BIRDS—The Beat of IRD Stories’ investigated the RPE65-related IRDs illness experience through the analysis of narratives (1) to reveal the practical, emotional and social issues linked to these conditions as experienced by patients, caregivers and healthcare professionals, and (2) to understand the patient’s journey and expectations regarding the gene therapy, to finally provide insights to foster the knowledge on RPE65-related IRDs and clinical practice.

The present research article focuses on the first goal (1); another study addressed the second one.27 Although other studies integrated the perspectives of both patients and caregivers,28 29 to the best of our knowledge, this is the first project that also engages the retinologists and hospital-based multidisciplinary professionals (MDTs) in investigating the RPE65-related IRDs illness experience in Italy.

Methods

Research design and setting

The project was conducted in Italy between July and December 2020 and targeted paediatric and adult patients with an RPE65-related IRD, their caregivers, retinologists and MDT professionals involved in their care pathway. Participants were enrolled from five eye clinics specialised in IRDs (online supplemental file 1) across Italy. In July 2020, the steering committee—composed of five retinologists working in these centres and a patient association (PA) member—participated in an online meeting conducted by researchers from Istituto Studi Direzionali (ISTUD), Healthcare Area to be trained in NM and to discuss the project’s goals and design; the Steering Committee, together with other IRD specialists from these centres, were then invited to engage patients and caregivers in participating in the research by accessing the project’s webpage http://www.medicinanarrativa.eu/birds.

A clinical RPE65-related IRD diagnosis, without a minimum length of follow-up time postdiagnosis, or the caregiving of a person with an RPE65-related IRD constituted the eligibility criteria for patients and caregivers, as well as the willingness to share their illness experience; however, the ability to write or communicate in Italian was critical for the inclusion.

Data collection

Researchers followed the Web Content Accessibility Guidelines 2.130 to ensure survey accessibility. Patients were invited to share their narratives either by writing or recording an audio file; also, caregivers were allowed to support paediatric patients in writing their narratives following the project’s data collection tools. Narratives were anonymously collected through the Alchemer platform, available on the project’s webpage. Afterwards, raw narratives were downloaded as Microsoft Excel spreadsheets.

A sociodemographic survey and an illness plot,31 namely, a plot related to the illness experience, were addressed to patients and caregivers; evocative and open words characterised the illness plot to facilitate individual expression32 and chronologically guide the narrative to identify changes over time. The retinologists’ caring experience was gathered through the parallel chart,33 that is, a personal notebook, parallel to the clinical one, in which to write down thoughts and feelings in a plain language.34 The patients described in parallel charts could not coincide with patients participating in the project. Overall, these investigation tools (online supplemental file 2) addressed two common aspects: (1) the personal and social experience of RPE65-related IRDs from early symptoms onwards and (2) the VRQoL perception and the current daily life with RPE65-related IRDs.

Supplementary data

bmjopen-2022-061080supp002.pdf (74.7KB, pdf)

Furthermore, in-depth interviews35 were conducted with MDT professionals involved in IRD care pathway and a PA member, caregiver of a person with an RPE65-related IRD, to facilitate the emergence of patient-related and care pathway-related issues further and to delve into organisational aspects without proposing to these professionals the introspective experience of writing; the interviewees approved the transcripts before the analysis.

The investigation tools were designed by two ISTUD researchers with different academic backgrounds and reviewed by the steering committee to reduce any cognitive bias.

Patient and public involvement

Researchers did not engage patients and caregivers in (1) developing the research design and tools, (2) interpreting and discussing the results and (3) contributing to the writing or editing of this document.

Analysis

Researchers analysed the sociodemographic data through descriptive statistics; answering survey questions or filling in fields in the illness plots and parallel charts was not mandatory, so sample size may vary. Narratives were entered into NVivo software36 for coding and content analysis.37 Three narratives for each group and one in-depth interview were collectively coded to assess the consistency across team members; then, each narrative and in-depth interview were separately coded and reviewed during weekly peer debriefings to limit any interpretation bias.

Open interpretive coding was employed to identify and analyse the emerging contents in all narratives and in-depth interviews. Moreover, adult patients’ and caregivers’ narratives and parallel charts were classified following: (1) Kleinman’s classification,23 which identifies disease-related, illness-related and sickness-related aspects in narratives, respectively, concerning the biomedical description of a condition, its personal and emotional experience, and its social and cultural perception; (2) Bury’s classification,38 which distinguishes among contingent narratives (concerning a condition’s immediate effects on daily life), core narratives (connecting the illness experience to deeper and cultural levels of meaning) and moral narratives (highlighting an evaluative and social dimension). Researchers did not apply retrospective classifications of narratives to paediatric patients’ narratives since their caregivers’ in-writing support could have affected the narrative style and the word choice.

Researchers asked the participants to describe RPE65-related IRDs through a metaphor to trace spontaneous meaning associations related to the illness experience through daily language.39

The steering committee discussed the results to address the emerged issues and data interpretation collectively. Researchers followed the Standards for Reporting Qualitative Research guidelines.40

Results

Three paediatric and 5 early-onset adult patients and 8 caregivers participated in the project, as well as 11 retinologists specialised in IRDs, who wrote 27 parallel charts; all patients chose to share their experience in writing. In-depth interviews were conducted with five MDT professionals—that is, two genetic counsellors, two psychologists and one orientation and mobility (O&M) instructor—and one PA member. Table 1 summarises the sociodemographic data of participants, including non-responders as a separate category.

Results are presented along four main lines: (1) the RPE65-related IRDs experience analysed through narrative classifications and metaphors; (2) the emotional issues before and on the clinical diagnosis; (3) VRQoL perception, the condition’s impact on daily life and participants’ expectations; (4) insights from in-depth interviews. Narratives informed (1) and (2), while (3) was investigated through both narratives and quantitative data from the survey; in-depth interviews alone informed (4). Figures 1–3 and tables 2–5 provide quotes from the narratives, while four narratives are available in English in online supplemental file 3; we reduced the risk of reidentification by applying different codes from those used to identify participants during data collection.

Patients’ and caregivers’ emotions before and at the diagnosis of RPE65-related IRD

Patients
 Before diagnosis Normal (38%) I have always felt normal. I never had the feeling that the slight differences I noticed could be a problem, or part of a problem. (Patient 004)
Uncomfortable (62%) I felt their disappointment, their concern… They were not happy with me, and I felt wrong, because my answers were wrong. I couldn’t see, and I couldn’t help but guess… (Patient 002)
 At diagnosis Identification (29%) Somehow, finally identifying the problem brought me out of my limbo: for years, I had been the child who saw little during the day and who couldn’t see at night; now I finally knew why. I became familiar with terms such as “blindness”, “low vision”, or “disability”, concepts that would later radically change my future. (Patient 001)
Neutral (71%) Honestly, I wasn’t much affected. The disease has always been part of me. I grew up with it, I gradually got used to it. (Patient 004)
Caregivers
 Before diagnosis Worry 50% I felt helpless, terrified, and afraid. (Caregiver 003)
Helplessness 50% I felt terrible, because I understood the challenge, but I couldn’t do much, except hold her hand. (Caregiver 006)
 At diagnosis Hopelessness 75% I felt terrible. It’s something you don’t expect: a hereditary disease of a genetic nature in a family where there were no known cases seems impossible. (Caregiver 008)
Fear for children 25% In the beginning, it scared me: the fear that our other children could suffer from a similar condition. Our anxiety decreased with time: I saw her, I saw she was restricted but not blocked, which gave me courage. (Caregiver 005)

Table 3.

Retinologists’ emotions at first visit and at the beginning of the care relationship

At the first visit A challenge for both clinician and patient 37% – I thought that this visit was a challenge for us both: for her, it meant undergoing new tests and knowing the results; for me, it meant dedicating myself to another person to whom I could dedicate my care. I also thought that she might have access to treatment in the future, and I was ready and willing to facilitate this.(Parallel chart 007)
Hope 30% – I thought it was essential to follow her carefully from a clinical perspective, and that it was imperative to have a genetic test. When she showed it to me, I realized that she had a treatable mutation, which gave me hope.(Parallel chart 015)
Sorrow 22% – Poor child, he is not living his life like his healthy peers.(Parallel chart 002)
Empathy with patient or caregiver 11% – I thought that he was the same age as me, but that he had a completely different visual situation from mine. I stepped out of the treating doctor’s shoes, and I found myself projected into an essentially human dimension. I put myself in her shoes and listened to her story with my heart as well as my ears.(Parallel chart 006)
At the beginning of the care at the beginning of the care relationship Emotional involvement and motivation 58% – I was impressed by what I was seeing, powerless but at the same time full of motivation and hope. I knew the child’s mutation, and I imagined that—given his young age—he might have a therapeutic chance. I leveraged this last point in my talk with his parents, trying to give them a cautious hope and making them understand that this specific genetic mutation meant being severely visually impaired, but also the possibility of being cured in a not distant future.(Parallel chart 005)
Helplessness 30% – Despite my knowledge, I felt powerless, unable to give immediate and concrete answers to many of his practical problems.(Parallel chart 019)
Sense of guilt 12% – I felt ashamed… I’m lucky, I think I have a successful life, and yet I often get irritated or discouraged by stupid things, while he always seems happy to live his life, despite everything.(Parallel chart 021)

The current feelings of participants: distribution and quotes from narratives

Patients
 Uncertainty 25% Today I feel poised between light and shadow. I feel like someone who chases a ball without ever reaching it. I am 42 years old, and I have spent my life being told that science works miracles, and that life is long, and that progress for me will come soon. I am 42, though, not 10… My sight is progressively worsening. I feel tangible differences over a few months, days in some cases. I can remember things from a few months ago, visual details that I no longer see today. In fact, it’s not that I don’t see them: I perceive them as covered by a veil. Glossy… Like old photographs, but far less poetic… (Patient 001)
 Discomfort, sadness 25% I feel sad: when mum or dad are driving, in the afternoon or in the evening, I do not see the road, I only notice a few lampposts. (Patient 007)
 Serenity, hope 50% Today I feel hopeful for the future. I try every day to accept my challenges and to live with serenity. If the situation gets worse, I know that I will have to find different ways. It will be hard, maybe even unpleasant, but it will be possible. If the situation improves, thanks to gene therapy, I will be pleased. (Patient 002)
Caregivers
 Acceptance 38% I feel I am an integral part of my son’s life. I live in symbiosis with him. Everything is more manageable: I manage to find solutions quite easily to meet his needs during his constant difficulties. Let’s say that everything is always about having an obstacle to overcome… It’s never easy, and sometimes it’s mentally exhausting. (Caregiver 003)
 More serenity 62% I know that we are doing our best to understand her condition better and, if possible, to start the therapy. The knowledge that we are doing our best brings me serenity. (Caregiver 005)
Retinologists
 Positive feelings 44% I’m feeling comfortable. Able to do my job without hiding my human side. Open to questions and ready to give competent and precise answers. Willing to help but aware of my limits, my role, and my possibilities. (Parallel chart 006)
 Commitment 37% I feel obliged to give him what he hasn't had so far. (Parallel chart 012)
 Motivation 19% I realize that it is a mutual gift. It reassures me to see her grow strong and able to face tomorrow despite her condition. I feel good with her, comforted by her positive attitude. (Parallel chart 010)

Macrothemes (MT) reported by MT professionals and PA representative interviewed:quotes from in-depth interviews

Managing IRDs
  • In some people, the degenerative process begins during adulthood. They “unconsciously” erase all their previous visual experiences: it’s a psychological reaction to the condition. Thus, they really need a “carer” because they can no longer do anything. Their mind forgets and cannot retrieve all the skills they possessed before from their store of experiences. On the other hand, in children who are used to this type of vision from an early age, visual function adapts, even if it gradually diminishes. They can create compensatory strategies more quickly, even if, while working on it, we realize that their visual acuity or visual field have worsened. (Interviewee 002)

Communication of the diagnosis
  • )…Colleagues who are not familiar with this condition are sometimes caught off guard. In the past, there have been communication issues.(…)Over the years, I have seen everything: from diagnoses not being communicated even when clear and evident, to children being told to learn Braille. Sometimes prognoses were communicated incorrectly; patients perceived them as crude, or they were told not to have children, because they would all be suffering from the same condition. (Interviewee 001)

  • We still have situations where the diagnosis is communicated violently: unfortunately, there is no cure for the disease, blindness could occur, but we do not know when… Verbal violence is where any kind of hope is taken away.(…)The main issue after the diagnosis is the psychological one. Suppose the diagnosis is communicated together with the possibility of recuperation, in which case one can deal with it somehow; but if it is expressed without this possibility, people don’t even undergo check-ups anymore. (Interviewee 004)

Attention to partner and parental caregivers
  • Some couples,(…)when they discovered the condition experienced a crisis.(…)What I noticed is that the way a caregiver treats his/her partner changes a lot: It’s more imperative (Interviewee 002)

  • A parent cannot serenely accept the condition of a child. Mothers are confronted with this issue daily, that is, they are considered “good mothers” if they can accept it, and this translates into the thought “I am not a good mother, I will not be a good mother”.(…)These parents often call the child “sick”. Disability is not a disease, but a condition. In pregnancy, parents expect to have a “healthy” child: the hope is to regain this healthy child, even when it is objectively impossible. (Interviewee 003)

Lack of knowledge of IRDs
  • In terms of daily life, people with this condition experience uncertainty, which is not even daily, but hourly. They may not see the same things at 10:00 and 10:30 am, because of a series of parameters that come into play: size, permanence, brightness, which give the retina a different visual function. So, this uncertainty generates other insecurities, and often triggers profound depressive states. This is not understood by other people. Often, at school, teachers do not understand how the child could see the blackboard at the beginning of the lesson and not at the end. The explanation is evident to those who know these disorders: maybe the sun’s angle had changed, of fatigue may come in to play, together with a series of parameters that determine a visual loss. (Interviewee 002)

  • I believe that initiatives are needed to allow people gain experience. For children, we could think of initiatives in school, which should be carried out regardless of the presence in the class of a child with this condition. We need to create a “culture”(…), a culture of confrontation with diversity. (Interviewee 003)

New investigation tools
  • The dimension of being with others is entirely missing: all activities are investigated as if they were carried out by the person alone, but rarely people with this condition are alone, especially after sunset. (Interviewee 003)

The RPE65-related IRDs experience in the narratives

Overall, almost all classified narratives highlighted illness-related aspects23 (figure 1); adult patients’ narratives lacked a clinical language, which conversely characterised 63% of the caregivers’ narratives and 37% of the parallel charts. Sickness-related issues were present in 50% of the caregivers’ narratives and in 11% of the parallel charts, while they emerged in all adult patients’ narratives.

Core narratives38 prevailed in parallel charts (74%) and were equally reported (50%) as moral narratives by caregivers (figure 2); only parallel charts presented contingent narratives (11%). Moral narratives were prevalent among adult patients (60%), while discomfort, disbelief (particularly at school) and the search for independence represented three spontaneously emerged issues in all narratives.

Metaphors were clustered into four thematic groups (figure 3): (1) those referring to light and hope, used by patients (33%) and in parallel charts (15%); (2) those concerning limitations and impairment, equally reported (50%) by patients and caregivers; (3) those related to darkness and mist, used by caregivers (33%) and in parallel charts (40%) and (4) and metaphors denoting pain and isolation, almost equally used by patients and caregivers, and in parallel charts.

Emotional issues on the clinical diagnosis and the clinical encounter

Patients reported having had the first signs of visual impairment at 2 years and 3 months of age (median value; range 0,5–6). In narratives, all patients reported issues that arose during early childhood, and that their parental caregivers identified as critical, for example, being attracted by light sources or tripping (In the evening, my parents used to cover the kitchen lamp, otherwise I would spend hours just staring at it, Patient 002). As shown in table 2, patients described early living with an RPE65-associated IRD either as uncomfortable (62%), mainly referring to the feeling of ‘being wrong’, caused by the informal tests or eye examinations they were subjected to by their parents, or—conversely—normal (38%), since they did not have any standard of comparison to evaluate their sight. Caregivers reported having felt worried (50%) or helpless (50%) in the same years. During the communication of the clinical diagnosis, 71% of patients had no reaction, while the other 29% reported that it allowed them to identify their condition; conversely, parental caregivers (75%) felt hopeless, while partner caregivers (25%) reported concern for the hereditariness of the condition.

Table 3 summarises the clinicians’ feelings the first time they met their patients and at the beginning of the care pathway. During the first visit, 37% of parallel charts reported the thought that the path would have been challenging, while 30% reported hopefulness over the care options; conversely, 22% focused on a sense of sorrow for the patient and 11% on the empathy with patients or caregivers. At the beginning of the care relationship, clinicians felt on one side emotionally involved or motivated to do their best (58%), and on the other side helpless (30%) or ‘guilty’ for being in a privileged situation compared with the patient (12%).

In addition, 33% of the parallel charts highlighted the importance of showing empathy from the very beginning of the care relationship.

As for the currently living with an RPE65-related IRD (table 4), patients reported a sense of uncertainty (25%), due to increasing visual impairment or discomfort and sadness (25%); conversely, 50% reported to feel serene or hopeful, also considering the possibility of undergoing gene therapy. Caregivers declared to have accepted the condition (38%) and to live more serenely (62%), due to the awareness of having done their best. In parallel charts, clinicians reported positive feelings (44%), dedication (37%) and motivation (19%) toward patients.

VRQoL perception and daily living with RPE65-related IRDs

Online supplemental file 4 presents survey data on patients’ and caregivers’ evaluation of RPE65-related IRDs impact on patients and their day-to-day tasks in relation to low light conditions; figure 4 provides an overview of essential data.

Patients reported an increasing impact on main daily activities after sunset; thus, they referred both a severe impact on driving (100%) and cooking (100%), and no impact on the use of smartphones (86%) regardless of light conditions. Caregivers reported higher levels of limitation for patients in some activities even before sunset, such as reading, using digital tools or smartphones, washing, moving around; however, they reported fewer limitations in driving and cooking before sunset (100% partially limited). Considering an open coding of VRQoL domains in patient narratives, the limitation in activities was the prevalent issue, concerning 100% of patients’ narratives. Mobility limitation (–The city becomes more and more hostile. I am afraid of tripping, bumping into things, hurting myself, taking a wrong turn, being followed, and having to flee from a danger without being able to do so, Patient 001), health concerns (–I am sad and cry. I ask my mother if my eyes will ever be able to see well, Patient 007) and emotional well-being issues (–I cannot accept that I cannot do many things anymore, and I cannot admit that this leads me to close myself off, Patient 006) emerged in 75% of patients’ narratives.

Nevertheless, further survey data showed that 72% of patients considered their VRQoL good, and 14% excellent (figure 5); thus, they reported that RPE65-related IRDs have enough impact on the performance of their daily activities (83%). Fifty per cent of caregivers defined their patient’s VRQoL acceptable, and only 38% good; conversely, 30% and 14% reported that RPE65-related IRDs have a low—or no—impact on patients’ performance of daily activities, respectively.

Addressing future perspectives, 71% of patients reported their hope to live serenely, both within their family and in the social context (–I just want my loved ones to see me calm and serene. […] I could not bear to see my relatives feeling bad for me, Patient 006), and 29% their hope to receive gene therapy (–Thinking about tomorrow, I would like to receive gene therapy, Patient 002); caregivers also stated to await gene therapy (50%). Clinicians hope to maintain a high quality of care in 41% of parallel charts, to improve their interpersonal skills and therapeutic possibilities for patients in 37%, and to be able to give them real hope in 22% (–Sometimes I think that gene therapy has already become a reality, and I feel that I am living a surreal experience. […] I wish that what I perceive as surreal today soon becomes reality, Parallel chart 007).

Overall, participants described writing as a positive experience: 80% of patients reported that narrative was a positive experience, and 20% stated to have felt a sense of freedom in sharing the illness experience. Twenty-seven per cent of the caregivers’ narratives and 21% of the parallel charts reported to consider it useful to raise awareness about these conditions; however, they also highlighted negative feelings, such as fatigue or sadness, in 14% and 8% of cases, respectively.

Insights from in-depth interviews

Five macrothemes transversely emerged from the in-depth interviews with MDT professionals and PA member (table 5):

  1. The O&M instructor described the gap occurring between early-onset patients, who can develop compensatory strategies over time and adult-onset patients, more likely to lose their previous visual experience. Thus, early-onset patients may experience their sight as ‘normal’; in this sense, the psychologists highlighted the importance to psychologically support patients on the communication of the clinical diagnosis, when introducing the notion of ‘impairment’.

  2. According to all interviewees, psychological support should be provided throughout the care pathway to improve communication and avoid misleading messages that could make patients feel that they ‘could do nothing more’. Furthermore, as also maintained by the genetic counsellors and the PA member, a more careful communication would allow the patient to keep an active perspective on the care pathway and early address rehabilitation programmes.

  3. All interviewees addressed the RPE65-related IRDs impact on parental and partner caregivers. While the latter may face a couple crisis due to the progression of the impairment, the former often deal with the failure of the ‘perfect child’ dream, the hope that their children will heal and a strong sense of guilt for the inheritability of the condition. Since caregivers project these complex feelings on patients, potentially impacting their care pathway, a psychological support should be provided to help them accept this condition.

  4. All interviewees highlighted the lack of knowledge of IRDs among the general public and society. The O&M instructor stressed that the link between visual impairment and changing light conditions is challenging for those who do not know these diseases. The psychologists confirmed that this is also critical in the school environment. One psychologist and the PA member mentioned the need to create an IRDs ‘culture’ and to address the diversity issue.

  5. Furthermore, one psychologist focused on the need for investigation tools integrating quantitative questionnaires to address the interpersonal dimension of daily activities, especially after sunset or in low light conditions.

Discussion

The project represents the first effort to investigate RPE65-related IRDs in Italy through NM, simultaneously addressing the perspectives of patients, caregivers and treating retinologists and collecting insights from MDT professionals and PA members.

The co-presence of illness-related and sickness-related aspects23 and the lack of a clinical language in patient narratives highlighted the centrality of the personal and social dimensions of living with an RPE65-related IRD in narrating the illness experience and trying to make sense10 of the condition; the prevalence of moral narratives38 supports this suggestion. The employed classifications allowed related themes to emerge in narratives spontaneously: patients declared to have manifested the first signs of visual impairment during early childhood and reported a discomfort mainly due to the informal testing they were subjected to by their parents, together with repeated eye examinations, before the clinical diagnosis; at school, their visual impairment is misunderstood or questioned by their teachers, who are not aware of the relationship between visual impairment and changing light conditions. In-depth interviews confirm the lack of knowledge about IRDs among the general public and society, as well as at school, where patients also experience stigma41 since their visual issues are addressed like cognitive impairments. Further investigations on the school environment may integrate studies on the patients’ discrimination at their workplace42 and studies on the patients’ feeling of being often patronised.10

Early-onset patients perceive their sight as ‘normal’, finding out to be ‘impaired’ only after the clinical diagnosis or by interacting with their peers in the school environment. As emerged from the in-depth interviews, the notion of ‘impairment’ should be carefully introduced to support the patients’ awareness of their condition. This issue may be further explored and integrated with studies on making sense and coping with IRDs,10 12 while careful communication should be adopted throughout the care pathways.

The search for autonomy emerges as related to the health concerns for the progressive sight loss and the emotional well-being issues showing anxiety for the future. Findings confirm that RPE65-related IRDs significantly impact patients’ VRQoL in terms of activity and mobility limitations: while changing light conditions do not change the use of digital tools or smartphones, activities such as driving and cooking remain challenging, regardless of the light conditions; moreover, the capability to perform daily activities is compromised by low light conditions, as also shown in studies addressing IRD critical effects on lifestyle choices.11 43 Nonetheless, many patients reported having a good VRQoL, suggesting that they have found strategies to cope with the condition in the absence, so far, of a therapeutic solution; these coping strategies should be further investigated. Two considerations may be emphasised. On the one side, the narratives and survey data show misalignment between the patient’s and the caregiver’s perception of the former’s limitation in activities and in VRQoL, where patients report a higher perceived VRQoL, and conversely a lower performance while carrying out daily tasks: we remark that patients’ coping strategies may represent a possible explanation and—at the same time—not visually impaired caregivers may have a different perception of IRD impact on patients’ life; however, this issue needs further investigations. On the other side, the search for autonomy is linked with the perception that relying on others is a limitation, confirming previous studies on this topic.11

The metaphors used by patients to describe RPE65-related IRDs highlight not only limitations and pain, but also lights and hope. Conversely, the association with images recalling darkness emerges from caregiver narratives and parallel charts; in particular, caregivers do not use any positive image to describe RPE65-related IRDs.

In contrast with patients, caregiver narratives largely focus on disease-related aspects23; however, the presence of sickness-related and illness-related aspects suggests their emotional commitment to the patient’s well-being. Furthermore, moral narratives38 reveal the sense of guilt experienced by caregivers about the hereditariness of the condition, which is also addressed within in-depth interviews: while partner caregivers may face a couple crisis on the onset of the condition, parental caregivers experience the failure of the ‘perfect child’ dream and struggle to accept the condition. Misalignment in the patients’ perception of their VRQoL, metaphors and the emotional issues reported also suggest the complexity found by caregivers in coping with these conditions.

Parallel charts show that retinologists are personally and emotionally involved in the care relationship, as suggested by the prevalence of core narratives38 and reported their feelings at the beginning of the care pathway, despite being less focused on social RPE65-related IRDs aspects. Retinologists emerge as being motivated to find the most suitable therapeutic pathway, as well as emotionally committed to patients; for the first time in similar NM projects, clinicians report a clear sense of guilt for being ‘healthy’ compared with their patients.

These are only preliminary findings; however, they can provide initial insights on the importance of a multidisciplinary RPE65-related IRDs clinical practice:

  1. RPE65-related IRDs critically impact several quality-of-life domains, while the emotional aspects of RPE65-related IRDs emerge as crucial while making sense of the condition and during the clinical encounter: the tension between the individual and the social dimensions of these conditions emerged as informative of the care pathway challenges and real-life experiences, and may be better addressed through new investigation tools, as claimed by the in-depth interviews. The NM approach has proved suitable for this purpose since sharing the illness experience by writing allows for more introspective and reflective knowledge, that may integrate the one-to-one level of in-depth interviews used in researching the living with a certain condition.

  2. The emotional burden of caregiving remains poorly investigated. Nonetheless, narratives show that caregivers deeply participate in the patient’s illness experience, while the in-depth interviews recommend a psychological support to help them accept the condition, while potentially improving the care pathway.

  3. The need for an RPE65-related IRDs ‘culture’ emerges as crucial to acknowledge these conditions, to avoid perpetuating the stigma and the scepticism and to foster the debate on diversity at society level.

Since narratives were anonymous, we are not able to precisely state the misalignment between patients and caregivers regarding the performance of daily activities and the perception of VRQoL; moreover, the voluntary participation in the project may have constituted a selection bias and included mostly patients more comfortable with writing. Further investigations are needed to examine in more details the issues which spontaneously emerged, also involving the work sphere. The annual incidence of RPE65-related IRDs explains the low number of participating patients44; however, the narratives collected suggest a strong dedication to the project and a relationship of trust between patients, caregivers and the retinologists from the centres involved. Finally, the data collection phase partially coincided with the local measures decided by the Italian government to contain the SARS-CoV-2 pandemic, with consequences on the clinical follow-up and the participation in the project.

Conclusion

The project investigated the practical and emotional issues of RPE65-related IRDs as experienced by patients, caregivers and retinologists, and provided insights from MDT professionals and PA members. It represented the first Italian project that simultaneously addresses and integrates these perspectives, whose comparison allowed to provide preliminary suggestions useful for the clinical practice and the knowledge of RPE65-related IRDs. NM allowed to connect the impact of RPE65-related IRDs on quality-of-life domains with real-life experiences, emerging as informative in raising suggestions to improve the care pathway for these conditions.
