Abstract

PURPOSE: We report a complication involving a transient inversion of Bell's phenomenon observed following extensive levator resection performed to treat aponeurotic ptosis.
CASE SUMMARY
A 22 year old female patient complained of ptosis of both eyelid. The levator function of both lid was good, and a normal corneal protection mechanism was observed. The patient underwent levator resection and several reoperation because of asymmetrical lid height and entropion. Inversion of Bell's phenomenon was observed in the postoperative period. Eye with Bell's phenomenon reverted to normal within 1 month after final operation, and there were no corneal erosion. Lubricating eyedrop was used frequently during the postoperative period.
CONCLUSIONS
It is important to consider that abnormal cases of Bell's phenomenon sometimes manifest after repetitive and extensive levator resection and to keep a close watch on the cornea while providing it with ample lubrication.

(A) Postoperative view of a patient immediately after suture removal following the third levator resection in the right eye and the second operation in the left eye showing inverse Bell's phenomenon on eye closure. The lagophthalmos in the right eye enables observation of the inversion of Bell's phenomenon. (B), (C), (D) Both eyeballs roll downward on attempted voluntary eyelid closure against resistance.
