Increased eyelid pigmentation associated with use of latanoprost.

Abstract

To report increased eyelid pigmentation as an adverse side effect associated with topical latanoprost. Case report. A 62-year-old Korean woman with normal-tension glaucoma developed bilateral increased eyelid skin pigmentation 4 months after beginning treatment with latanoprost in both eyes. Clinical examinations were performed, and external photographs were taken. Latanoprost was discontinued. Periodic examinations revealed that the eyelid skin pigmentation gradually diminished 1 month after the cessation of the drug, and decrease in pigmentation continued over 4 months of follow-up. An increase in eyelid skin pigmentation is a possible complication of topical latanoprost therapy, and the cessation of the drug can result in loss of induced pigmentation in humans.
