Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older with homonymous hemianopsia or quadrantopsia who can provide informed consent and communicate in English.
✕Probably not a fit
Patients with a history of light-induced seizures may not benefit from this study due to the potential risk of triggering seizures.

What this trial studies
This study aims to evaluate the effectiveness of visual stimulation using a PowerPoint slide set to enhance peripheral vision in patients suffering from hemianopsia due to stroke or brain injury. The research will involve a prospective design where eligible patients will undergo visual field testing and receive computer screen visual stimulation. The study will collect various patient data, including demographics and medical history, to assess the potential recovery of visual fields. The hypothesis is based on the possibility of axonal sprouting or re-routing in the brain following injury.
Why it matters
Potential benefit: If successful, this approach could significantly improve the quality of life for patients with visual field deficits following a stroke or brain injury.
How similar studies have gone: There is clinical equipoise regarding the effectiveness of visual stimulation therapies, with mixed results reported in previous studies.

Show full inclusion / exclusion criteria
Inclusion Criteria: All patients 18 years of age or older with a homonymous hemianopsia or quadrantopsia, who can provide informed consent, and communicate in English. Exclusion Criteria: * The flashing lights from thge automated perimeter and PowerPoint program can potentially trigger photic seizures. Therefore patients with light-induced seizures are excluded.
