Eye-Search: A web-based therapy that improves visual search in hemianopia.

Area of Science:

• Neuroscience
• Ophthalmology
• Rehabilitation Medicine

Background:

• Hemianopia, a visual field defect from posterior cerebral hemisphere lesions, significantly impacts daily living.
• Current practice-based therapies for hemianopia are limited in availability.
• Compensatory eye movement training can enhance visual function in affected patients.

Purpose of the Study:

• To evaluate the efficacy of a web-based visual search saccade retraining therapy (Eye-Search) for hemianopia.
• To assess improvements in visual search times and real-world functional outcomes.

Main Methods:

• Utilized a web-based therapy (Eye-Search) to retrain visual search saccades into the blind hemifield.
• Enrolled 78 hemianopic patients for an 11-day therapy regimen (800 trials).
• Measured changes in search times and patient-reported functional improvements.

Main Results:

• Significant improvement in search times into the impaired hemifield by an average of 24%.
• Patients reported functional gains in visually guided everyday activities.
• The therapy demonstrated a positive impact on real-world outcomes.

Conclusions:

• Web-based Eye-Search therapy is an effective intervention for improving visual search in hemianopia.
• The therapy translates to tangible improvements in patients' daily lives.
• Eye-Search offers a accessible and effective rehabilitation option for hemianopic patients.
