Abstract

Purpose: To determine effect of refractive error and color vision on Stereopsis and evaluate the frequency in children.

Methods: The hospital based; descriptive, cross-sectional study was conducted at paediatric department from July to December 2020.

Results: 29 (51.8%) out of 56 found myopic, 12 (21.4%) hypermetropia and 15 (26.8) astigmatism in right eye and 30 (53.6%) found myopic, 13 (23.2%) hypermetropia and 13 (23.2%) astigmatism in left eye.

21 had normal or 55 sec of arc, 6 have mild 170 sec of arc and only 2 patients had weak 340 sec of arc.12 hypermetropia patient 10 have normal or 55 sec of arc and 2 have mild 170 sec of arc.15 astigmatism patient 6 had normal or 55 sec of arc of stereopsis, 6 have mild 170 sec of arc of stereopsis and 3 patient had weak 340 sec of arc Stereopsis without refractive correction. With refractive correction on Frisby test, 56 (100%) patients had normal or 55 second of arc stereopsis. Out of 56 of patients, 52 (92.9%) patients had normal color vision (Trichromats) and only 4 (7.1%) patients found with blue-yellow color vision defect (Tritan). Tritan color vision anomaly found in 3 females out of 20 and out of 32 male 1 had found with tritan color vision anomaly.

Conclusion: Improvement of stereopsis after correction and no effect of color vision on stereopsis. Tritan (Blue) color vision anomaly was higher in female as compare to male.
