Correction of enophthalmos in the anophthalmic orbit.

Enophthalmos with an associated superior sulcus syndrome is a common finding in the anophthalmic socket. Two common causes are: (1) progressive relaxation of the lower eyelid leading to downward migration of the prosthesis and associated ectropion formation; and (2) decreased volume of the orbit. Relaxation of the lower eyelid is corrected with repair and support using autogenous fascia lata. Decreased volume of the orbit is corrected with implantation of RTV silicone. The surgical techniques, surgical complications, ocular prosthetic modifications and follow-up on 20 patients are discussed.
