Complete ptosis as a result of removal of epibulbar lipodermoid.

Partial ptosis following epibulbar epidermoid removal is a known complication. The mechanism is generally thought to be symblepharon following aggressive dissection, injury to the levator aponeurosis, or injury to the branch of the ocular motor nerve to the levator muscle. We now report a case of complete ptosis thought to be neurogenic in origin. The possible mechanism is discussed.
