Abstract:AIM:To investigate the effects of different types and differentials of anisometropia on vision development and stereopsis and to analyze the relevance between anisometropia with monocular amblyopia and stereopsis.
METHODS:From January 2013 to December 2014, 326 patients with anisometropia went for their first visits were collected with clinical data. Best corrected distant and near visions, near stereopsis after the correction were recorded, in order to analyze the proportions of amblyopia and abnormal stereopsis.
RESULTS:As the differentials of anisometropia increased, the corrected far and near vision in patients with high refractive error decreased, the incidence of amblyopia increased. There was also a growth on the incidence of abnormal stereopsis which made a statistically difference. Amblyopia and abnormail stereopsis occurred earliest and was the most in hyperopia group, which was different from other groups and the discrepancy was statistically significant.
CONCLUSION:The differentials of anisometropia affect the percentages of abnormal stereopsis and amblyopia directly. The differentials of amblyopia caused by hyperopic anisometropia is the least which is related to the lack of regulatory function in patients with high refractive error and their incapability to develop proper near vision.
