Anisometropia Amblyopia Improved by Perceptual Learning and Patching
To compare the effects of perceptual learning with patching on improving visual acuity and contrast sensitivity in payient with anisometropic amblyopia.
Procedure: computer program and patching
|Study Design:||Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind
Primary Purpose: Treatment
- Corrected amblyopic logMAR visual acuity and contrast sensitivity function
|Study Start Date:||January 2005|
|Study Completion Date:||January 2007|
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.
