A randomized trial of near versus distance activities while patching for amblyopia in children aged 3 to less than 7 years.

ABSTRACT:

Purpose

To determine whether performing near activities while patching for amblyopia enhances improvement in visual acuity.

Design

Randomized clinical trial.

Participants

A total of 425 children, aged 3 to <7 years, with amblyopia (20/40-20/400) that was caused by anisometropia, strabismus, or both, and that persisted after treatment with spectacles.

Methods

Children were randomized to 2 hours of patching per day with near activities or 2 hours of patching per day with distance activities. Instruction sheets describing common near and distance activities were given to the parents. Study visits were scheduled at 2, 5, 8, and 17 weeks. In weeks without a visit, weekly telephone calls were made to the parent to monitor and encourage compliance during the first 8 w
