Urgent and Emergent Eye Care Strategies to Protect Against COVID-19

Abstract

Objective

This article presents additional strategies to the medical professional and support tactics to keep both the health care provider and patient as safe as possible during the COVID-19 pandemic.

Observations

Follicular conjunctivitis has been reported as an early sign of infection or during hospitalization for severe COVID-19 disease. It has been confirmed that COVID-19 is transmitted through both respiratory droplets and direct contact. Another possible route of viral transmission is entry through aerosolized droplets into the tears, which then pass through the nasolacrimal ducts and into the respiratory tract. For nonemergent care, eye care providers should use telehealth. Eye care providers should prioritize patient care in order of absolute necessity, such as sudden vision loss, sudden onset flashes and floaters, and eye trauma. In those cases, exposure should be minimized. The close proximity between eye care providers and their patients during slit-lamp examination may require further precautions, such as shields, barriers, and mask use to lower the risk of transmission via droplets or through hand to eye contact.

Conclusions

All nonemergent eye care appointments should be delayed or conducted remotely. For emergent in-person appointments, careful and appropriate adherence to Centers for Disease Control and Prevention recommendations may minimize exposure for both the health care provider and patient.

Amid the COVID-19 pandemic, eye care professionals should be aware of important guidelines and consider using telehealth to keep both the health care provider and patient as safe as possible. This article is intended to give an update on the ever-changing landscape of eye care due to COVID-19. The Centers for Disease Control and Prevention (CDC) recommends that health care facilities and clinicians delay all elective ambulatory provider visits.¹ In addition, the American Academy of Ophthalmology (AAO) recommends that all ophthalmologists cease providing any treatment other than urgent or emergent care.² Our goal is to equip the eye care provider with the best practice guidelines for seeing urgent and emergent eye conditions.

COVID-19 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and its symptoms range from mild to severe respiratory illness, fever, cough, fatigue, and shortness of breath.¹ Diarrhea is common early on with infection and loss of taste and smell have also been reported.¹ Follicular conjunctivitis has also been reported, either as an early sign of infection or during hospitalization for severe COVID-19 disease.^2–4 The incubation period of COVID-19 falls within 2 to 14 days according to the CDC.⁵

It has been confirmed that COVID-19 is transmitted through both respiratory droplets and direct contact. Another possible route of viral transmission is entry through aerosolized droplets into the tears, which then pass through the nasolacrimal ducts and into the respiratory tract.⁶

PREPARATIONS PRIOR TO OFFICE VISIT

It is essential for the eye care provider to prioritize patient care in order of absolute necessity, such as sudden vision loss, sudden onset flashes and floaters, and eye trauma. In cases of potentially sight threatening pathology, it is in the best interest of the patient to conduct a face-to-face appointment. Therefore, it is important to implement new guidelines and protocols as we continue to see these patients (Figure 1).

Need to Know.

• The American Academy of Ophthalmology (AAO) and Centers for Disease Control and Prevention recommend protection for the mouth, nose, and eyes when caring for patients potentially infected with SARS-CoV-2^1,2;

• The AAO issued guidance recommending all eye doctors to suspend routine eye examinations, providing only urgent or emergent care²; and

• Reports suggest mild follicular conjunctivitis easily transmitted by aerosol contact with conjunctiva or hand to eye contact.^2–4

Prior to the patient entering the medical facility, measures should be implemented to minimize exposure risk. This can be done over the telephone or at vehicle entrance screening stations. The triage technician answering the telephone should have a script of questions to ask. The patient should be instructed to come into the office alone unless, for physical or mental reasons, a caregiver is required.

SARS-COV-2 SCREENING QUESTIONS

Preparedness through risk mitigation strategies are recommended with a targeted questionnaire and noncontact temperature check at the clinic or hospital entrance. Below are some general questions to further triage patients exposed to SARS-CoV-2.

• Do you have fever or any respiratory symptoms?

• Do you have new or worsening cough or shortness of breath?

• Do you have flulike symptoms?

• Have you been in close contact with someone, including health care workers, confirmed to have the COVID-19?

If the patient answers yes to any of the above questions, the CDC urges health care providers to immediately notify both infection control personnel at your health care facility and your local or state health department.^1,2 In regions currently managing significant outbreaks of COVID-19, the AAO recommends that eye care providers assume that any patient could be infected with SARS-CoV-2 and to proceed accordingly.² If urgent eye care is needed, a referral call should be made to a hospital or center equipped to deal with COVID-19 and urgent eye conditions. When calling the referral center, ensure adequate staffing and space and relay all pertinent information along with receiving approval from the treating physician.

FACE-TO-FACE OFFICE VISITS

Once it has been determined that it is in the best interest of the patient to be seen in a face-to-face visit, the patient should be instructed to call the office when they arrive in the parking lot. The CDC recommends limiting points of entry upon arrival and during the visit.¹ As soon as an examination lane is ready, the patient can then be messaged to come into the office and escorted into the examination room.

An urgent or emergent ophthalmic examination for a patient with no respiratory symptoms, no fever, and no COVID-19 risk factors should include proper hand hygiene, use of personal protective equipment (PPE), and proper disinfection. Several studies have documented SARS-CoV-2 infection in asymptomatic and presymptomatic patients, making PPE of the up most importance.^2,7,8 PPE should include mask, face shield, and gloves. Currently, there are national and international shortages on PPE and a heightened topic of discussion concerning mask use, effectiveness with extended wear, and reuse. Please refer to the CDC and AAO websites for up-to-date guidelines (Table).^1,2 According to the CDC, N95 respirators are restricted to those performing or present for an aerosol-generating procedure.⁹

It is recommended that the eye care provider should only perform necessary tests and procedures. Noncontact tonometry should be avoided, as this might cause aerosolization of virus particles. The close proximity between eye care providers and their patients during slit-lamp examination may require further precautions to lower the risk of transmission via droplets or through hand to eye contact. The patient should be advised not to speak during the examination portion and the AAO also recommends a surgical mask or cloth face covering for the patient.² An additional protective device that may be used during the slit-lamp exam is a breath shield or a barrier shield (Figures 2 and 3).² Some manufacturers are offering clinicians free slit-lamp breath shields online.

INFECTION PREVENTION AND CONTROL MEASURES

Last, once the patient leaves the examination room, it should be properly disinfected. A disinfection checklist may be made to ensure uniform systematic cleaning. Alcohol and bleach-based disinfectants commonly used in health care settings are likely very effective against virus particles that cause COVID-19.¹⁰ During the disinfection process, gloves should be worn and careful attention paid to the contact time. Contact time is the amount of time the surface should appear visibly wet for proper disinfection. For example, Metrex CaviWipes have a recommended contact time of 3 minutes; however, this varies depending on type of virus and formulation, check labels or manufacturers’ websites for further directions.¹⁰ Also, the US Environmental Protection Agency has a database search available for disinfectants that meet their criteria for use against SARS-CoV-2.¹¹

In an ever-changing environment, we offer this article to help equip providers to deliver the best possible patient care when face-to-face encounters are necessary. Currently nonurgent eye care follow-up visits are being conducted by telephone or video clinics. It is our goal to inform fellow practitioners on options and strategies to elevate the safety of staff and patients while minimizing the risk of exposure.
