Report of a Case.
—A 34-year-old healthy woman was examined in 1972 and treated for retinal holes with lattice degeneration by transconjunctival cryopexy to the right eye. From 1972 to 1982 she underwent five complete ophthalmologic examinations with normal findings.In February 1988, the patient was again examined, complaining of intermittent halos of short duration and decreased visual acuity in her left eye of 1 month's duration. Her best corrected visual acuity was 20/20 OD and 20/25 OS. Intraocular pressure was 17 mm Hg OU. Slit-lamp examination of the right eye was unremarkable. In the left eye, a membrane that was separated from the stroma was hanging down with a free edge at the central posterior cornea, without corneal edema or signs of iritis (Fig 1). Gonioscopy
