Abstract

Authors studied 73 patients(91 eyes) of the congenital blepharoptosis who were received the levator resection at Busan National University Hospital during recent 4 years and could do follow up studies for at least 6 months(average 9.7 months). Results obtained as follows; 1. Success rate of the levator resection was 67 percents. 2. Causes of the levator resection were poor levator function of 2 to 4 mm or combined anomalies, such as superior rectus weakness, epicanthus, and blepharophimosis. 3. Average amount of the levator resection per 1 mm difference of levator function was 1. 85 mm. 4. It was concluded that the primary surgical indication for the congenital blepbaroptosis of simple type with the levator function of 5 mm or more was resection of the levator muscle.
