目的:探讨近视性屈光参差对双眼视觉的影响。方法:选择屈光度差≥2D近视92例,分别检查裸眼视力、屈光状态、最佳矫正视力、矫正前后双眼视功能,分析屈光参差对双眼视觉的影响。结果:(1)戴框架眼镜矫正视力≥0.6与<0.6组近立体视锐度比较,差异非常显著(P<0.01)。(2)高度屈光参差组(2～5.75D)与重度屈光参差组(≥6D)矫正后近立体视锐度比较,差异非常显著(P<0.01)。(3)近视性屈光参差者矫正前后融合功能及远、近立体视功能比较,差异显著(P<0.05)。(4)近视性屈光参差者矫正后,具有正常近立体视功能的屈光参差度数为(3.125±0.685)D,具有异常近立体视功能的屈光参差度数为(3.928±1.549)D,立体视锐度缺失的屈光参差度数为(6.817±2.667)D。结论:近视性屈光参差对双眼视觉有显著影响。
Objective: To investigate the effect of myopic anisometropia on binocular vision. Methods: Ninety-two cases of myopia with diopter difference ≥2D were selected. Visual acuity, refractive status, best corrected visual acuity (BCVA) and binocular visual acuity (BCVA) were measured before and after correction. The effect of anisometropia on binocular vision was analyzed. Results: (1) There was a significant difference (P <0.01) in the stereoacuity of glasses with corrected visual acuity between ≥ 0.6 and <0.6. (2) There was a significant difference (P <0.01) in stereoacuity after correction between high anisometropia group (2 ~ 5.75D) and severe anisometropia group (> 6D). (3) There were significant differences in the fusion function and far and near stereopsis before and after correction of myopic anisometropia (P <0.05). (4) The number of anisometropia with normal near stereopsis was (3.125 ± 0.685) D, the number of anisometropia with abnormal near stereoscopic vision was (3.928 ± 1.549) D, The number of anisometropia with absence of stereopsis was (6.817 ± 2.667) D. Conclusion: Myopic anisometropia has a significant effect on binocular vision.
