Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals aged 18-90 with hemianopia diagnosed more than six months post-lesion.
✕Probably not a fit
Patients who have received previous treatment for low vision rehabilitation or have serious ocular diseases may not benefit from this study.

What this trial studies
This study evaluates the effectiveness of biofeedback training on microperimetry in patients with hemianopia resulting from brain injuries. Participants will undergo five sessions of 20 minutes each, where they will be stimulated with light and sound to engage the best residual areas of their visual fields. Visual tests and quality of life questionnaires will be administered before and after the training to assess improvements. The goal is to enhance visual and spatial perception, which is often impaired in these patients.
Why it matters
Potential benefit: If successful, this approach could significantly improve visual function and quality of life for patients suffering from hemianopia.
How similar studies have gone: While there is limited large-scale research on biofeedback training for hemianopia, similar approaches in visual rehabilitation have shown promise in smaller studies.

Show full inclusion / exclusion criteria
Inclusion Criteria: Hemianopia cases with more than 6 months from the date of the lesion, previously diagnosed accordingly by micro perimetry and other tests as needed, 18-90 years old, ability to follow the visual and auditory stimuli and training instructions. Exclusion Criteria: Previous or current treatment for low vision rehabilitation, ocular diseases, other serious clinical conditions not related to the hemianopia, both eyes with media opacity that impairs microperimetry testing, lack of ability to perform the tests and training.
