Conjunctiva-Müller's muscle excision to correct anophthalmic ptosis.

We treated 35 eyelids with ptosis and anophthalmos by resecting conjunctiva and Müller's muscle. Before surgical intervention all patients were evaluated by an experienced ocularist who, if necessary, modified or refit the prosthesis. All eyelids had a positive response to 10% phenylephrine hydrochloride. Preoperatively, the margin reflex distance-one (MRD-1) of the ptotic eyelids ranged from -2.0 to +3.5 mm. The amount of conjunctiva-Müller's muscle excision ranged from 7.25 to 9.25 mm. Following surgery, the average change in MRD-1 was 3.33 mm. Thirty-one eyelids (88.6%) achieved a post-operative level within 1 mm of the opposite eyelid. There were two overcorrections and two undercorrections. Postoperatively, no patients had any compromise of the superior fornix, socket dryness, or inability to retain their prosthesis. Resection of conjunctiva and Müller's muscle is a simple and effective method to treat ptosis associated with anophthalmos.
