Retrocorneal membrane with Descemet's detachment.

PURPOSE: To describe a unique case of retrocorneal membrane with large Descemet's detachment. METHODS: Case report of a 65-year-old man reported intermittent cloudy vision in his left eye. The patient underwent serial ocular examinations and slit-lamp photography over 6 weeks. RESULTS: The patient had an inflammatory-appearing membrane that covered 60% of the posterior cornea, with a subtotal Descemet's detachment. Vision was stable at 20/20, and the cornea remained clear. The patient was empirically treated with topical neomycin/polymyxin/dexamethasone, sodium chloride, and oral acyclovir, and his symptoms improved; however, the retrocorneal membrane persisted. CONCLUSION: This unusual clinical finding may represent reduplicated Descemet's membrane with partial Descemet's detachment secondary to occult deep herpes simplex keratitis. Other possibilities include spontaneous or traumatic Descemet's tear and detachment.
