Results for treatment of central visual impairment
| Study | Study design | Aim/Objective | Number of participants | Type of population | Intervention | Time/ duration of intervention |
|---|---|---|---|---|---|---|
| Beasley and Davies (2013) | Randomized crossover study | Consider the use of spectral filters on visual search in stroke patients | n = 17 | Stroke | Spectral filters and visual search training | 2 weeks using the filters. 2 weeks washout. 2 weeks of using placebo filters |
| Freeman and Rudge (1987) | Prospective observational study | Identify the orthoptic problems associated with stroke |
n = 76 excluded = TIA and other medical conditions |
Stroke | Registered blind (n = 2), observation (n = 20), glasses (n = 5) | Within 1 week post stroke. Follow‐up ranged from 1 week to 4 years |
| Lotery et al. (2000) | Prospective Observational | Examine visual status of patients after stroke | n = 77 | Stroke | Glasses | Within 2 weeks of admission with stroke |
| Pollock, Hazelton, & Brady, (2011a) | Survey | To explore the current assessments, protocols, referrals, and treatments of visual problems after stroke by OTs | n = 55 | Occupational Therapists | Visual field, eye movement disorders and visual neglect (scanning training, patching/ prisms, ADL training, reading aids/ magnifiers, information, environment modification) |
45% of OTs said they would treat within 2 weeks of stroke. 75% said they would treat patients within 6 weeks of stroke. 38% said they would continue treatment up to 3 months |
| Pollock et al. (2012b) | Cochrane systematic review | Determine if interventions for age‐related visual problems improve functional ability following stroke | 0 studies found | – | – | – |
| Rowe & VIS (2011) | Prospective multicenter cohort | To identify all patients referred with suspected visual impairment who had reported reading difficulty to establish the prevalence of ocular and non ocular causes | n = 915 (n = 177 with reading difficulty) | Stroke | Advice, reading strategies, typoscopes, low vision aids, occlusion, prisms, exercises, CVI registration. |
Review appointments within 3 months. Duration of individual treatments not specified |
