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.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 18-90 with hemianopia diagnosed more than six months post-lesion.

Not a fit: Patients who have received previous treatment for low vision rehabilitation or have serious ocular diseases may not benefit from this study.

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 performed: While there is limited large-scale research on biofeedback training for hemianopia, similar approaches in visual rehabilitation have shown promise in smaller studies.

Eligibility criteria
