Thirty-one patients presented for surgical correction of unilateral hypotropia of the globe and blepharoptosis. The hypotropia and pseudoptosis were corrected by Knapp procedures. The Bell's phenomenon was thereby improved, allowing safe correction of the true ptosis, generally by an anterior levator resection whose magnitude depended on measured levator function.
31例患者因单侧眼球下斜和上睑下垂前来接受手术矫正。眼球下斜和假性上睑下垂通过Knapp手术进行矫正。从而改善了贝尔现象,使得能够安全地矫正真正的上睑下垂,一般通过提上睑肌前路切除术进行,其切除幅度取决于所测量的提上睑肌功能。
