Visual acuity through Bangerter filters in nonamblyopic eyes.

ABSTRACT:

Purpose

To describe the amount of visual acuity degradation induced by Bangerter filters in the better seeing eye and to evaluate its stability over time in children with moderate amblyopia.

Methods

Visual acuity with and without a Bangerter filter was measured in the nonamblyopic eye of 186 children with moderate amblyopia who were then treated with either patching or the Bangerter filters. A 0.2 filter was used for amblyopia of 20/80 and a 0.3 filter for amblyopia from 20/40 to 20/63. For the 89 children randomized to Bangerter filters, visual acuity was also measured in the nonamblyopic eye with and without the filters at both 6 weeks and 12 weeks after initiating treatment.

Results

Mean degradation in visual acuity of the nonamblyopic eye at baseline was 5.1 logMA
