Surgical Comparative Observation of Congenital Blepharoptosis

ABSTRACT

The author evaluated 63 patients(95 eyes) of congenital blepharoptosis whowere operated by frontalis sling and external levator resection at the Keon Yang Medical Foundation Kim's Eye Clinic. To obtain the best results in blepharoptosis, it is necessary to evaluate degree of levator function, amount of ptosis and its etiology. The results are as follows 1. The majority(78%) were operated at the age between the first and the second decade. 2. Levator function of congenital ptosis was poor(under 4mm) in 84 eyes and fair(5~7mm) in 11 eyes. 3. The author obtained good surgical result in 20 eyes(80%) by frontalis sling and in 35 eyes(92%) by external levator resection. 4. Most common complication was undercorrection(8 cases). 5. External levator resection is the primary choice of operation for ptosis with poor levator function(3~4mm).
