Effect of Visual Acuity and Stereopsis on Ocular Deviation
Purpose: The aim of the present study is to correlate Visual acuity and Stereopsis in the presence of ocular deviation.
Methods: A pilot, cross sectional, observational study was performed at tertiary eye care centers. Subjects with 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. Visual acuity was assessed with Log Mar chart and recorded
in log units and Stereopsis was assessed with Titmus fly test.
Results: 30 subjects were included in the study. 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. Visual acuity was deteriorated to 0.193 log units.
Stereopsis was deteriorated to 80 sec of arc in the presence of ocular deviation
Conclusions: Visual acuity and Stereopsis decreases significantly with increase in ocular deviation.
