Abstract :
Purpose: Normal development of stereopsis is based on good binocular vision and might get disrupted by a number of factors like refractive errors, amblyopia and/or strabismus. The study was undertaken with the aim to analyze impact of refractive errors with and without amblyopia and/or strabismus on stereopsis in school going children of rural Haryana.
Methods: Subjects in the age group of 5-15 years without any organic disorders were included over a period of two months. Cycloplegic refraction was undertaken and stereo acuity was demonstrated on Titmus fly stereogram under standard conditions. Subjects were divided into three groups: Plain refractive errors (isometropic or anisometropic) (group-I), subjects with amblyopia (group-II) and with strabismus (group-III). Further subgroups were made as per the type of refractive error.
Results: Subjects in group-I retained better stereo acuity as compared to group-II (P
