Factors Affecting Stereopsis in Patients with Refractive Accommodative Esotropia

Abstract

Objective: Aim of this study was to evaluate possible risk factors affecting stereopsis in patients with refractive accommodative esotropia (RAE). Materials and Methods: The retrospective investigation was performed on the records of children with RAE. Two groups were made according to the presence of stereopsis. The presumed onset age of RAE, age at the initial refractive correction, mean best-corrected visual acuity (BCVA), mean angle of deviations in near and distance, presence of strong fixation preference, spherical equivalent (SE), and cylindrical error values, mean interocular differences in BCVA were compared between groups. Besides, mean SE and ocular movement disorders were also evaluated and compared between groups, statistically. Results: The mean age of 66 children was 10,7±2,9 years. The mean follow-up time was 65,3±25,6 months. 38 children had measurable stereoacuity and 28 children who had not and composed groups 1 and 2, respectively. There were statistically significant differences between groups in terms of mean BCVA, the interocular difference in BCVA, mean SE, presence of amblyopia, and the presence of inferior oblique overaction. Conclusion: Presence and depth of amblyopia, lower best-corrected visual acuity, higher spherical equivalent, and concomitant inferior oblique overaction were found to be potential risk factors for the maldevelopment of stereopsis in patients with refractive accommodative esotropia.
