Retinal Pigment Epithelial Detachment Following Topical Travoprost Therapy

Prostaglandin analogs, including travoprost, are widely used to lower intraocular pressure in primary open-angle glaucoma. While generally safe, rare posterior segment changes have been reported. Retinal pigment epithelial detachment (RPED) associated with travoprost is uncommon and poorly documented. We report three patients who developed serous RPED shortly after initiating topical travoprost, none of whom had preexisting macular disease. Optical coherence tomography (OCT) confirmed the detachments, and complete anatomical and visual recovery occurred following discontinuation of travoprost and initiation of alternative glaucoma therapy. A clear temporal relationship was observed between drug initiation and RPED onset. The absence of clinical or OCT features suggestive of alternative diagnoses-such as central serous chorioretinopathy, age-related macular degeneration, or pachychoroid spectrum disorders-combined with consistent reversibility, suggests a possible association between travoprost and RPED. These findings emphasize the importance of early recognition and timely intervention, as RPED appears fully reversible when identified promptly, preventing potential persistent visual impairment.
