the records of astigmatic children were reviewed and any deviation was investigated at near and distance. refractive errors, stereopsis, convergence insufficiency were also evaluated. children were divided into two groups according to the presence of amblyopia and ocular deviations and other parameters were compared between groups.
The aim of the study was to evaluate deviations in children with ≥1,75 diopter (D) astigmatism with or without amblyopia.
The records of children with ≥1,75 D astigmatism were investigated. Subjects with and without amblyopia composed group 1 and 2, respectively. The mean age, gender, amount and type of deviation, presence of convergence insufficiency (CI), stereopsis, time of initial spectacle use and follow-up time, differences in best corrected visual acuity (VoD) and spherical equivalent (SE) between eyes were noted and compared between the groups. Best corrected visual acuity (BCVA), mean SE, astigmatism measurements were also noted and compared between amblyopic, fellow and non-amblyopic eyes.
