Anisometropia Amblyopia Improved by Perceptual Learning and Patching
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
To compare the effects of perceptual learning with patching on improving visual acuity and contrast sensitivity in payient with anisometropic amblyopia.
Condition or disease
Procedure: computer program and patching
Patients with anisometropic amblyopia were randomized to patching or perceptual learning group. Corrected amblyopic logMAR visual acuity and contrast sensitivity function were measured at four-weekly intervals until visual acuity stabilized or amblyopia resolved. Improvement in visual acuity, contrast sensitivity, and the resolution of amblyopia were compared between groups.
