Reactivation of Herpetic Keratitis in a Patient after Using Two Different Prostaglandin Analogues

ABSTRACT

PURPOSE: To report a case of herpetic keratitis after administration of two different prostaglandin analogues. CASE SUMMARY: A 68-year-old female with a history of herpetic keratitis in her right eye after using latanoprost seven years previous presented with redness, mild ocular pain and tearing in the same eye. She had also been prescribed travoprost eye drops for both eyes for uncontrolled glaucoma one month earlier. The cornea in her right eye showed a dendritic epithelial defect with focal epithelial erosions. Travoprost treatment was discontinued, and the herpetic keratitis recovered completely in ten days with acyclovir ointment and oral agent. No further recurrence was observed in the following six months.
