Comparison of the correlation between refractive errors (myopia hyperopia) with stereopsis

Abstract

Introduction: Stereopsis is ability for spitual perception that is an important factor influencing person’s functions especially in some jobs such as medicine, aviating. In this research, the correlation between refractive errors (myopia & hyperopia ) with stereopsis was studied. Materials and Methods: This research is a descriptive-analytic-cross sectional study that has performed on 96 cases in Feiz eye hospital in Isfahan city at second half of year 1383. The degree of refractory errors was determined by autorefractometer. Then with Polaroid Spectacles and target sheet of Titmus test stereoacuity was defined. Age, sex and educational levels were recorded. Data was analyzed by SPSS II. Results: A significant correlation between refractional error rate with stereoacuity was seen. In myopia group, mean of stereoacuity was better. Difference of stereoacuity in these groups was 46 sec of arc (CI=95, r = 0.753, p
