远、近视性屈光参差视功能对比研究

摘要

AIM: To investigate the effect of both myopic and hyperopic anisometropia on binocular vision. METHODS: Totally 238 patients with corrected anisometropia and 30 normal children were tested with both stereogram and synoptophore for their near stereoacuity and binocular vision. The correlation of anisometropia and binocular vision was studied statistically. RESULTS:The number of normal near stereoacuity and distance fusion range of myopic anisometropia was significantly higher than that of hyperopic anisometropia. A few of hyperopic anisometropia had normal stereopsis. Most of low anisometropia group had sub -normal stereopsis, while high, severe anisometropia group without stereopsis.Most of myopic anisometropia group had normal stereopsis or sub-normal stereopsis. CONCLUSION:The hyperopic anisometropia produces a more profound effect. Relationship between anisometropia and stereopsis are analyzed according to nature.%目的：对比分析远、近视性屈光参差对患者双眼视功能的影响。　　方法：对238例屈光矫正后的屈光参差者和30例正常者进行近立体视和同视机三级视功能检查，并记录其结果。　　结果：近视性屈光参差远、近立体视及融合功能正常者的例数高于远视性屈光参差者。远视性屈光参差组有正常立体视者少，低度屈光参差组以亚正常立体视者为主，而高、重度屈光参差组多无立体视；近视性屈光参差组多有正常立体视或亚正常立体视。　　结论：近视性屈光参差的双眼视功能总体优于远视性屈光参差，但屈光参差与立体视的关系应按性质分别进行分析。
