A randomized trial of increasing patching for amblyopia.

ABSTRACT:

Objective

After treatment with refractive correction and patching, some patients have residual amblyopia resulting from strabismus or anisometropia. We conducted a clinical trial to evaluate the effectiveness of increasing prescribed daily patching from 2 to 6 hours in children with stable residual amblyopia.

Design

Prospective, randomized, multicenter clinical trial.

Participants

A total of 169 children aged 3 to <8 years (mean, 5.9 years) with stable residual amblyopia (20/32-20/160) after 2 hours of daily patching for at least 12 weeks.

Intervention

Random assignment to continue 2 hours of daily patching or increase patching time to an average of 6 hours/day.

Main outcome measures

Best-corrected visual acuity (VA) in the amblyopic eye after 10 weeks.<
