A Clinical Study of Surgical Results on 456 Blepharoptosis

ABSTRACT

We have performed surgical procedure in 456 patients(582 lids) with blepharoptosis. The surgical results were studied retrospectively according to age, sex, etiology, surgical methods, surgical results, and postoperative complications. Of all patients, male accounted for 58.6% and monocular ptosis(72.4%) occurred more often in the right eye(37.5%) than in left eye and binocular ptosis was found in 126 cases(27.6%) and most of ptosis proved to be congenital(92.3%) in origin. The 3~4mm group(63.9%) was the highest in the amount of blepharoptosis and the function of levator was most common in less than 4mm group(69.0%). The surgical results on cosmesls were obtained successfully in 501 lids(86.1%). The postoperative complications were undercorrection(11.7%) that was most frequent, and followed by overcorrection(3.5%), exposure keratitis(3.3%), poor lid contour(2.6%), Infection(1.2%) and others(0.5%).
