Choroidal Thickness in Strabismus and Amblyopia Cases

Abstract

Purpose: The aim of our study was to examine the effect of hypermetropia and anisometropic, exotropic, and esotropic amblyopia on choroidal thickness. Methods: A prospective, cross-sectional, comparative study of 120 children under the age of 16 years was conducted. Choroidal thickness was measured in patients with hypermetropia, anisometropia, esotropia, exotropia, and controls. Results: The mean subfoveal choroidal thickness in the control and hypermetropia groups was 323.9+/-69.0 mu m and 348.9+/-64.5 mu m, respectively. Mean choroidal thickness in amblyopic and fellow eyes was 387.4 and 351.9 mu m in anisometropic, 353.8 and 338.7 mu m in exotropic, 347.5 and 336.5 mu m in esotropic, and 389.3 and 359.3 mu m in esotropic+anisometropic groups, respectively. Choroid was significantly thicker in amblyopic eyes of anisometropic group compared to fellow (P=0.004) and control (P=0.03) eyes. The difference of choroidal thickness was not significant between both eyes and when compared to control eyes in the other groups. Conclusions: Anisometropic amblyopic eyes had thicker choroids compared to controls and fellow eyes. However the choroidal thickness was not significantly different between amblyopic and fellow eyes of esotropic or exotropic patients.
