目的:运用Sheard准则对集合不足的屈光不正患者的双眼视失平衡症状进行评估和诊治。方法:对2009-06以来18例集合不足的患者进行眼屈光检查,同时检测远近分离性隐斜,远近辐辏,正相对调节,调节状态,负相对调节,辐辏近点,调节幅度等眼动参数。计算AC/A参数,检测其对Sheard准则符合性,并利用该准则计算所需的棱镜处方。结果:近距棱镜不符合Sheard准则有14例(78%),其所需的基底朝内棱镜度数为(3.47±2.83)△。结论:临床上运用Sheard准则可有效地评估和诊治近距离用眼不适的集合不足患者。

·AIM:To evaluate and analyze binocular symptoms on convergence weakness patients by Sheard’s criteria.·METHODS:Eighteen patients were selected.For each subject,their oculomotor function included refraction,distance and near disassociated phoria,distance and near fusional convergence,vergence facility,near point of convergence,relative accommodation,accommodation facility and amplitude.Data were analyzed in light of Morgan normal values and Sheard criteria.·RESULTS:There were 14 cases(78%)who weren’t fit to Sheard criterion and they were demand to average(3.47±2.83)△ BO prisms on their nearly work.·CONCLUSION:Sheard criteria is effective diagnostic aids or guides to predict convergence weakness patients.·
