１９９３年以来，采用上睑提举试验检查法对１１８例单侧中或重度先天性上睑下垂患者进行检测，根据检查结果，对阳性率及与提上睑肌肌力的关系进行分析；将阳性患者随机分为对照组和试验组，对照组仍按常规方法手术，试验组则按提举后的上睑位置修改术式，术后三个月观察手术效果。试验组手术满意率为９２％，对照组为１２％。在单侧中、重度先天性上睑下垂，当对侧提上睑肌肌力低于１２ｍｍ时，提举试验检查法应做为术前的常规检查，纠正上睑位置假象，修改手术方案
Since 1993, 118 cases of unilateral or severe congenital blepharoptosis were examined by the eyelid lifting test, and the relationship between the positive rate and the levator muscle strength was analyzed according to the examination results. Positive patients were randomly divided into control group and experimental group. The control group was still operated according to the conventional method. In the experimental group, the position of upper eyelid was modified according to the lift, and the operation effect was observed three months after operation. The satisfaction rate was 92% in the experimental group and 12% in the control group. In unilateral, severe congenital ptosis, when the contralateral levator muscle strength is less than 12mm, lifting the test should be used as a preoperative routine examination to correct the upper eyelid position illusion, modify the surgical plan
