Abstract
Purpose
The purpose of the study was to report the outcome of posterior approach white-line advancement surgery for severe involutional aponeurotic ptosis.
Patients and methods
This was a retrospective review of an interventional case series of all patients undergoing surgery for severe involutional aponeurotic ptosis during a 42-month period at a single center. The inclusion criteria were severe involutional ptosis (upper eyelid margin reflex distance (MRD) ≤1 mm) undergoing posterior approach surgery. There was minimum 3-month follow-up. The main outcome measures were type of ptosis (primary or recurrent), preoperative margin reflex distance, levator function and eyelid skin crease height, presence of visible iris sign (VIS), documented unusual intraoperative findings, postoperative complications, and follow-up time.
Results
Of the 836 procedures for ptosis, 122 procedures (76 patients) met the inclusion criteria for this study. Mean postoperative follow-up was 28 (median 18, range 12–98) weeks. Success rates were 80.3% (98/122) overall, 81.5% (66/81) in the non-VIS group, and 78% (32/41) in the VIS group. There was no significant difference between the two groups (P=0.411). Failures were due to undercorrection, with <2 mm MRD in 75% (18/24), overcorrection with >4.5 mm MRD in 16.7% (4/24), and inter-eyelid height asymmetry of >1 mm in 8.3% (2/122).
Conclusions
Outcomes of ptosis surgery for severe aponeurotic ptosis using a posterior approach white-line advancement are comparable to, and possibly better than, anterior approach in eyelids with VIS.
