Purpose: To report a case of angiographically documented cystoid macula edema occurring after switching a pseudophakic patient from latanoprost to bimatoprost.
Design: Observational case report.
Methods: A 68-year-old man developed intense conjunctival hyperemia and cystoid macula edema after switching from latanoprost to bimatoprost 9 months after cataract surgery in an eye at low-risk for this cystoid macular edema.
Results: Bimatoprost was discontinued and diclofenac initiated. After 2 months, visual acuity and ocular hyperemia returned to baseline levels. Fundus examination revealed resolution of cystoid macula edema.
Conclusion: It is possible that pseudophakic eyes that develop intense conjunctival hyperemia associated with ocular hypotensive lipids might be at higher risk for developing cystoid macula edema.
