Abstract

Purpose: To study the influence of refractive error (RE) on subfoveal choroidal thickness (SFCT), macular thickness (MT) and retinal nerve fibre layer thickness (RNFLT) in Indian children with anisometropic amblyopia (AMA).

Methods: An observational cross-sectional study was conducted in children up to 12 years of age including 50 cases of unilateral AMA, 50 external controls (EC), and 50 emmetropes (EM) using SD-OCT.

Results: In anisohyperopic amblyopes, SFCT was significantly thicker than in all the 3 control groups (FE, EC, and EM) however the mean central MT (CMT) was found significantly thicker in FE and EM but not in EC.

In anisomyopic amblyopes mean CMT was found to be thinner than the 3 control groups but was statistically insignificant. The mean peripapillary RNFLT has significant thinning when compared to EC and EM, but not to FE.

Conclusion: RE has an influence on choroidal, retinal nerve fibre layer and macular thickness in children with AMA.
