DEVELOPMENT OF PACHYCHOROID PIGMENT EPITHELIOPATHY AND TRANSFORMATION TO CENTRAL SEROUS CHORIORETINOPATHY AFTER INTRAVITREAL DEXAMETHASONE IMPLANTATION

PURPOSE: To report first case of sequential development of pachychoroid pigment epitheliopathy (PPE) and central serous chorioretinopathy (CSC) after repeated intravitreal dexamethasone implantations for diabetic macular edema treatment. METHODS: We present a case of a 54-year-old man having intravitreal dexamethasone implant for bilateral diabetic macular edema. RESULTS: We observed development of pachychoroid pigment epitheliopathy, seen as a small pigment epithelial detachment on optical coherence tomography after a fourth dexamethasone implantation. A fifth implantation caused transformation of pachychoroid pigment epitheliopathy to central serous chorioretinopathy. CONCLUSION: Consecutive administration of dexamethasone implants may have a cumulative effect on retinal pigment epithelium, Bruch membrane, and choroid.
