Compliant, full-time occlusion effectively improves visual acuity in patients between 11 and 15 years of age who have amblyopia, according to an Indian study. Most older patients have a lasting improvement with or without maintenance patching, the study authors added.

Kanwar Mohan, MS, and colleagues at the Grewal Eye Institute treated 55 children between 11 and 15 years of age with full-time occlusion of their good eye until no further improvement in the VA of the amblyopic eye was observed during three consecutive follow-ups.

The mean improvement was 0.46 logMAR units. Of the patients, 32 had a mean follow-up of 17.6 months. Of those 32 patients, 29 maintained their improved vision. Maintenance occlusion therapy did not have a significant stabilizing effect on the improved VA.

The study is published in the March/April issue of Journal of Pediatric Ophthalmology & Strabismus.
