PURPOSE: The authors quantitated herpes simplex virus (HSV) DNA in tear film obtained from two patients who developed herpetic epithelial keratitis (HEK) during treatment with latanoprost and a beta-blocker. METHODS: The patient in case 1 is a 77-year-old female with bilateral open-angle glaucoma who had been treated with latanoprost and timolol for 11 months. She developed HEK in the right eye followed by HEK in the left eye one month later. Both eyes healed with administration of acyclovir. Ten months later, HEK recurred in the right eye. The patient in case 2 is a 45-year-old male with bilateral normal tension glaucoma who had been treated with latanoprost for two years. After concurrent treatment with nipradilol for five months, typical dendritic keratitis developed in the left eye. In both cases, a real-time PCR assay was used to quantify HSV-DNA in the tear film. RESULTS: In the patient in case 1, 71 copies of the HSV genome were detected in the tear film obtained from the right eye at the time of presentation with HEK. After one week of treatment with topical acyclovir ointment, the corneal epithelial defects healed and the number of HSV genome copies present in the tear film fell below the sensitivity limit of the assay. In the patient in case 2, 7.0 x 105 copies of the HSV genome were detected in the tear film from the left eye. After three days of topical acyclovir ointment, it healed and the HSV genome in the tear film became undetectable. CONCLUSIONS: Herpetic keratitis may occur during treatment with latanoprost and beta-blockers. The amount of HSV DNA detected in the tear film paralleled with the activity of the corneal lesion.
