The blepharoptosis has many causes and may be congenital or acquired, and due to a weakness of the levator or Muller's muscle. The management of blepharoptosis mainly depends on the degree of ptosis and the amount of levator function. The results
of
surgical correction of the blepharoptosis is determined by the nature of ptosis, methods of operation and surgeon's skill.
Authors had experienced 24(30 eyes) patients of blepharoptosis from August, 1989 to March, 1994. The results were obtained as follows;
Most of the patients were congenital in origin. The ratio of congenital versus acquired blepharoptosis was 18:6, monocular versus biocular was 12 : 6, male versus female was 9:9 and right versus left was 7:5. In the function fo the levator
muscle,
9
eyes were less than 2mm, 21eyes were between 2mm to 6mm. In review of postoperative complications, incidental lagophthalmos in sleeping and ptotic change at upward gaze were noticed in some cases, these symptomes were lmproved postoperatively
after
5
months. Overcorrection was found in 3 cases, undercorrection was found in 2 cases, eyelid fold deformity was found 1 case, exposure keratitis was found 1 case.
