不同类型屈光参差与弱视和立体视的相关研究

Study of different types of anisometropia for amblyopia and stereopsis

摘要:

目的：观察不同类型不同差值的屈光参差对视力发育和立体视形成的影响，分析屈光参差与单眼弱视、立体视之间的相关因素。

方法：收集2013-01/2014-12在我院门诊初诊屈光参差患者326例的临床资料，记录最佳矫正远、近视力，以及矫正后近立体视，分析弱视和立体视异常的比例。

结果：随着屈光参差差值的增大，高屈光眼远近矫正视力下降，弱视发生率增高，异常立体视增多，有统计学差异。远视组出现弱视和立体视异常最早且比例最大，有显著统计学差异。

结论：屈光参差差值的大小直接影响弱视和立体视异常的比例，远视性屈光参差形成弱视的差值最小，与其高屈光眼调节功能不足，近视力无法正常发育有关。

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.
