A Randomized Trial of Full-time Bangerter Filters versus Part-time Daily Patching for the Treatment of Moderate Amblyopia in Children
|
Protocol
|
|
Objectives:
- Primary:
- To evaluate the non-inferiority of Bangerter filters to 2 hours of daily patching as a primary treatment for moderate amblyopia (20/40 – 20/80) in children ages 3 to <10 years.
- Secondary:
- To determine the time course of visual improvement with Bangerter filter treatment.
- To compare patient quality of life, measured by a modified Amblyopia Treatment Index, between patients treated with patching vs. Bangerter filters.
- To determine whether the degree of blurring of sound eye visual acuity relative to the amblyopic eye visual acuity predicts improvement in acuity.
- To determine whether fixation preference is predictive of improvement in visual acuity.
