Outcome of Levator Resection in Congenital Ptosis with Poor Levator Function

Purpose: Purpose of the study is to evaluate the success of levator resection in
congenital ptosis with poor levator function.
Material and Methods: It was a single center, prospective, interventional case
series. The study was carried out at  Department of Ophthalmology, Bahawal
Victoria Hospital, Bahawalpur from March 2008 to November 2010. We selected
50 cases from outdoor department by universal sampling technique. Levator
resection was carried out in all 56 cases (eyes) of congenital Ptosis (with 06
bilateral cases) with poor levator function (less than 4mm) after taking informed
written consent. Patients were subjected to general anesthesia. Data was
collected on special proforma and was analyzed with the help of SPSS.
Results: The study population comprised of 56 eyes of 50 cases of congenital
ptosis. Male to female ratio was 3:1. Two bilateral cases were females and four
were males. Age ranged between 04-32 years (Mean = 14 years). About 75%
patients were between 13 and 24 years. The results were excellent in majority
(67.8%) with complete lid closure. Good results were seen in 17.85% with only
7.14% with fair and poor outcome each. The major cosmetic defect in all cases
was lid lag on extreme downward gaze. The operation is extremely laborious but
fully justified by the good results.
Conclusion: Levator resection in congenital Ptosis with poor levator function is
a viable option for cosmesis especially in unilateral cases
