PERBEDAAN PENGLIHATAN STEREOSKOPIS PADA PENDERITA MIOPIA RINGAN, SEDANG, DAN BERAT

Abstract

Background: Stereoscopic is the highest level of binocular vision. Disruption of stereoscopic can reduce the quality of life. One of the factor that can lead to stereoscopic impairment is refractive error. Myopia is a refractive error that has high prevalence and can affect stereoscopic vision. Aim: To determine the difference of the stereoscopic vision among patients with mild, moderate, and severe myopia. Methods: The study was observational research with cross sectional design and conducted at outpatient of Ophtalmology, Dr. Kariadi Hospital Semarang during March until May 2016. The subject were patients with mild myopia (n=16), moderate myopia (n=16), and severe myopia (n=16). Stereoscopic vision was measured using TNO stereotest with corrected visual acuity. The difference of stereoscopic vision among groups were analyzed using Kruskal-Waliis test and Mann-Whitney test. Result: Kruskal-Wallis test showed significant differences of stereoscopic vision among patients with mild myopia, moderate myopia, and severe myopia. Stereoscopic vision in patients with moderate myopia were 90 (60-480) arc sec, significantly worse than in mild myopia 60 (60-120) arc sec (p=0,006). Stereoscopic vision in patients with severe myopia were 120 (60-240) arc sec, also significantly worse than in mild myopia (p=0,002). There was no significant difference of stereoscopic vision among moderate myopia and severe myopia (p = 0.838). Conclusion: There were significant differences of stereoscopic vision among patients with mild myopia, moderate myopia, and severe myopia. Stereoscopic vision in moderate and severe myopia are significantly worse than mild myopia. Key words: Stereoscopic vision, Myopia, TNO stereotest.
