Abstract

Purpose: The present study aims to correlate contrast sensitivity in the presence of ocular deviation.

Methods: A pilot, cross-sectional, observational study was performed at tertiary eye care centers. Subjects with an Ocular deviation between 10 to 40 prism diopters, Corrected distance Visual Acuity should be greater than 6/18 and Age should be between 10 to 40 years of age were included in the study. Contrast sensitivity was recorded with Pelli Robson Contrast Sensitivity chart.

Results: 30 subjects were included in the study. All the patients were included with informed consent. Out of that, 16 subjects were in the age group of 11-20 years, 12 subjects were in the age group of 21-30 years and 2 subjects were in the age group of 31-40 years. 60% subjects were Female, and 40% subjects were Male. Mean scores of visual parameters were taken. Contrast sensitivity was deteriorated to 1.695 in the presence of ocular deviation.

Conclusions: In cases of ocular deviation, contrast sensitivity deteriorates significantly.
