Levator Muscle Reaction for Unilateral Congenital Ptosis Repair as Compared to Levator Plication

Levator Muscle Resection for Unilateral Congenital Ptosis Repair as Compared to Levator Plication

The aim of this study was to compare the outcome of levator muscle resection with plication in mild to moderate congenital unilateral blepharoptosis.

Blepharotosis is one of the most encountered oculoplastic problems. Blepharoptosis is an abnormal low lying upper eyelid margin more than 2mm below the superior corneal limbus in the primary gaze position.

It can be subdivided according to the amount of levator function into poor (0-5),fair (6-11) or good (12 or more) millimeter. It can be classified also according to the degree of ptosis into mild (2mm) moderate (3mm) and severe ( 4mm or more). Surgical options for each of these groups are based on levator function as well as the degree and the cause of ptosis.

Inclusion Criteria:

• mild to moderate simple unilateral congenital ptosis with good to fair levator function

Exclusion Criteria:

1. severe ptosis
2. poor levator function
3. poor Bell's phenomenon
4. lagophthalmos
5. diminished corneal sensation
6. completed congenital or acquired ptosis
7. history of previous lid surgery
