Abstract

Purpose: To evaluate the effect of ocular dominance on stereoacuity in experimentally induced anisometropia.Methods: In this clinical trial, 60 healthy adult volunteers 18-37 years of age (mean age: 25.58 years) without any ocular disease were emolled at Tabriz Nikookari eye hospital over a one-year period. Anisometropia (unilateral myopia) was induced by placing trial lenses over the dominant and non-dominant eyes in 1 diopter (D) increments ranging from 1-3 D. Stereoacuity was measured using the TNO, Randot and Titmus stereotests and values were converted into Neperian logarithm (In) and compared between the two eyes.Results: Of sixty adults including, 25 male and 35 female subjects, the right eye was dominant in 49 (81.7%) of cases. Stereoacuity levels were reduced proportionate to the degree of anisometropia in all participants.Mean stereoacuity was 4.3, 5.5 and 7.4 In for dominant eyes and 4.1, 5.4 and 7.3 In for non dominant eyes usig the TNO test by applying 1, 2 and 3 D lenses, respectively (P>0.05). Corresponding values were 3.5, 4.6 and 6.6 In for dominant eyes and 3.4, 4.6 and 6.5 In for non dominant eyes by the circles subcategory of Randot test, respectively (P>0.05). The scores were 3.8, 4.7 and 6.5 In for dominant eyes and 3.8, 4.7 and 6.4 In for non dominant eyes by the circles subcategory of Titmus test, respectively (P>0.05).Conclusion: Experimentally induced anisometropia could reduce stereoacuity. However, ocular dominance has no effect on the amount of stereoacuity reduction.
