PERBEDAAN PENGLIHATAN STEREOSKOPIS PADA PENDERITA ANISOMETROPIA RINGAN-SEDANG DAN BERAT

Abstract

Background : Anisometropia is one of the most prevalent refractive disorders in the world. It is categorized into three degrees which are mild, moderate and severe. The more severe the degree of anisometropia is, the higher the possibility of other visual impairments to occur. One of the visual impairment is stereoscopic vision impairment. Aims : To determine the differences in stereoscopic vision between two groups of patients: those having mild-to-moderate anisometropia and severe anisometropia Methods : A cross-sectional study with two groups of patients with mild-to-moderate and severe anisometropia was conducted in RSUP dr.Kariadi Semarang during March to May 2016. This study involved 28 subjects suffering from various degrees of anisometropia. Vision test was held to classify their degree of anisometropia and was followed by stereoscopic vision examination using TNO Stereotest. Results : Subjects who suffered from mild-to-moderate anisometropia had better stereoscopic vision’s mean (81.43 ± 58.159 arcseconds) compared to those suffered from severe anisometropia (300±40,7 arcseconds) with p=0,000 Conclusion : There is a significant difference of stereoscopic vision between two groups of subjects with mild-to-moderate anisometropia and severe anisometropia.
