Methods
Case report.
Results
A 76-year-old healthy male on latanoprost monotherapy for POAG polresented with sudden bilateral decreased vision. Examination showed bilateral dense corneal edema with loose epithelium. Aqueous fluid was positive for HSV-1 DNA on polymerase chain reaction (PCR). Latanoprost was discontinued, topical prednisolone acetate 1% eye, acyclovir 400 mg 5 times a day and combination of dorzolamide hydrochloride 2% and timolol maleate 0.5% twice daily were prescribed. The vision rapidly improved to 20/25 along with complete resolution of corneal edema within four weeks, with no recurrences over the next one year.
