Correlation between visual acuity, contrast sensitivity and depth of vision before and after partial time occlusion therapy in strabismic and anisometropic amblyopes.

Abstract

Partial occlusion therapy was performed in a comparative prospective study included a total of 49 eyes of 49 healthy pediatrics after dropping all incompliant patients or those who missed any follow-up, in the period from January 2020 to September 2020 divided into 2 groups: A. Anisometropic. B. Strabismic.

The results found in our study show that, apart from better improvement of contrast sensitivity in the anisometropic group, both groups got nearly equal benefit of occlusion therapy, the final values were better for anisometropics due to better initial values. Although they exhibited a rather similar progress course, anisometropic amblyopes had more reliable expectations of recovery that are largely dependent on the initial visual acuity.
