Anisometropia Amblyopia Improved by Perceptual Learning and Patching
Phase 3
Completed
- Conditions
- Anisometropic Amblypia
- Registration Number
- NCT00498641
- Lead Sponsor
- Tri-Service General Hospital
- Brief Summary
To compare the effects of perceptual learning with patching on improving visual acuity and contrast sensitivity in payient with anisometropic amblyopia.
- Detailed Description
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.
