Abstract

Purpose: To determine the factors in abnormal stereoacuity(worse than 120 seconds of arc by TNO stereo test-TNO) in patients with anisometropic amblyopia.<BR>Subject and methods: We retrospectively reviewed the charts of 27 patients with anisometropic amblyopia who had the best corrected visual acuity of >0.8 after treatment.Inclusion criteria were:anosometropia≥1.00 diopter, astigmatism≤1.5 diopter, absence of ocular and neurological disorders. We prescribed a complete correction glasses by cycloplegic refraction and part time occlusion. The patients were divided into two groups by the best TNO stereoacuity: group A with 21 patients who had stereoacuity of 120 seconds of arc or better;and group B with 6 patients who had stereoacuity worse than 120 seconds of arc. We statistically analyzed between the two groups;(1)total amount of occlusion worn (hours) to achieve the best visual acuity;(2)a correlation between the degree of anisometropia and the initial visual acuity;(3)a correlation between the degree of anisometropia and total amount of occlusion worn;(4)a correlation between the initial visual acuity and total amount of occlusion worn;(5)the improvement of stereoacuity before and after treatment.<BR>Result: (1)Total amount of occlusion worn was not significantly different between the two groups. (2)As for group A, a significant correlation was identified between the degree of anisometropia and the initial visual acuity (p<0.05) whereas as for group B, no significant correlation was identified. (3) Between both groups, there was no significant correlation identified between the degree of anisometropia and total amount of occlusion worn.(4) As for groups A, there was a significant correlation between the initial visual acuity and total amount of occlusion worn (p<0.05) whereas ,for group of B, no significant correlation was identified.(5) Between the two groups, a significant difference was identified in the improvement of stereoacuity before and after treatment between two groups(p<0.001).<BR>Conclusion: For patients with abnormal stereoacuity, there was no significant correlation identified between 1)the degree of anisometropia and the initial visual acuity and 2)between the initial visual acuity and total amount of occlusion worn.
