Cystoid macular edema occurring after intracameral bimatoprost implantation.

Purpose: This case report aims to report the development of cystoid macular edema (CME) unilaterally following the administration of bimatoprost implant (Durysta) injections in both eyes for the treatment of primary open-angle glaucoma (POAG).

Observations: An 84-year-old female patient, previously diagnosed with POAG, underwent bimatoprost implant (Durysta) injections in both eyes, spaced one month apart. Subsequently, the patient experienced a gradual decline in visual acuity in her left eye attributed to the development of CME. The condition resolved following a treatment regimen involving topical dexamethasone and nepafenac.

Conclusion: The use of bimatoprost implant may lead to the occurrence of CME. Ophthalmologists must vigilantly monitor patients post-implantation, especially if they exhibit visual symptoms or have risk factors for a CME.
