Abstract
Purpose
Latanoprost is a prostaglandin F2α analog that lowers intraocular pressure by increasing uveoscleral outflow. Herein we describe two cases of allergic contact dermatitis (ACD) to latanoprost.
Methods
A 69-year-old man with open-angle glaucoma developed erythematous erosive swelling of bilateral eyelids after 4 months of latanoprost therapy. An 84-year-old man with open-angle glaucoma had pruritic erythematous plaques on the bilateral lower eyelids after latanoprost therapy for 4 months.
Results
In both cases, latanoprost was discontinued and the condition gradually resolved in 1 month. The eyelid lesions recurred in days upon latanoprost rechallenge, but subsided after cessation of rechallenge.
Conclusions
ACD should be suspected if patients on latanoprost therapy have pruritus, erythema, swelling, or erosions on the eyelids even when the symptoms appear after several months of therapy, especially in the elderly.
