Purpose:

To compare the lower eyelid retraction following Lockwood’s ligament advancement versus retractor lysis associated with inferior rectus muscle recession.

Methods:

In this prospective, nonrandomized, comparative case series, patients requiring inferior rectus recession of 4 mm or more for managing vertical strabismus underwent Lockwood’s ligament advancement versus lower eyelid retractor lysis. Lower eyelid margin reflex distances (MRD2) and vertical deviation were documented preoperatively and postoperatively.

Results:

There were 10 patients in the Lockwood advancement group and 12 patients in the retractor lysis group. No statistically significant difference was found in duration of follow-up, preoperative vertical deviation, amount of inferior rectus recession, residual deviation, and preoperative lid status between the two study groups (p>0.10 for all parameters). The average change of MRD2 was 0.70± 0.70 mm in the Lockwood advancement group, as compared with - 0.1± 0.43 mm in the retractor lysis group (P=0.004).

Conclusion:

Retractor lysis is more efficient than Lockwood’s ligament advancement as a surgical modification to the inferior rectus recession to minimize postoperative lower lid retraction.
