COMPARATIVE EVALUATION OF THE STEREOACUITY IN SUBJECTS HAVING EMMETROPIA, ISOMETROPIA AND ANISOMETROPIA

Abstract

ABSTRACT
Background: Stereoacuity is a measure of stereopsis and the ability to distinguish variations in depth depending on
binocular disparity. A child's daily activities may be adversely affected by astereopsis impairment.
Objective: The current clinical investigation set out to assess stereoacuity in people with anisometropia, isometropia, and
emmetropia in comparison.
Methods: Seventy-two children, aged five to fifteen, were evaluated for the study. They were split into three groups:
emmetropes, including 250 subjects; isometropes, comprising 250 subjects; and anisometropes, comprising 202 subjects.
When measuring stereoacuity using a combination of contour targets, the Titmus stereo test was employed. Ambylopic
eyes were 78 and 129 among isometropes and anisometropes, respectively.
