目的探讨屈光参差在弱视形成中的作用。方法对远视性屈光参差、近视性屈光参差、对称性远视、对称性近视四组１３１１例患者的矫正视力在同等屈光度条件下进行对比分析。结果同等屈光度时远视性屈光参差屈光度高侧眼矫正视力明显低于屈光度低侧眼和对称性远视；近视性屈光参差高侧眼、低侧眼、对称性近视三者矫正视力无显著性差异；３５Ｄ以上对称性远视矫正视力明显低于对称性近视。结论远视性屈光参差在弱视形成中作用十分明显，除远视对视功能的损害外，屈光参差的存在更加重了视功能的损害。较低程度近视性屈光参差不导致弱视。对称性远视对视功能的损害明显强于对称性近视。
Objective To investigate the role of anisometropia in the formation of amblyopia. Methods The corrected visual acuity of 1311 patients with farsighted anisometropia, myopic anisometropia, symmetrical farsightedness and symmetrical myopia were compared and analyzed under the same diopter. Results When the same power was used, the corrected visual acuity of high refractive error anisometropia was significantly lower than that of low power and symmetrical hyperopia. The corrected visual acuity of high myopia, low myopia and symmetrical myopia was not significant Differences; 3. 5D or more symmetry hyperopia corrected visual acuity was significantly lower than symmetrical myopia. Conclusions Hypermetropia anisometropia plays a very significant role in the formation of amblyopia. Except for the impairment of visual function due to farsightedness, the presence of anisometropia worsens the impairment of visual function. A lower degree of myopic anisometropia does not lead to amblyopia. Symmetry Hyperopia damage to visual function is significantly stronger than symmetrical myopia.
