Abstract

Purpose: To report a 71-year-old male patient diagnosed with epiretinal membrane-induced intraretinal neovascularization.

Observations: The presence of an epiretinal membrane (ERM) was confirmed by Optical Coherence Tomography (OCT), fluorescein and indocyanine angiography. Optical coherence tomography angiography (OCT-A) revealed a neovascular membrane within the ERM. Intravitreal ranibizumab injections were administered three times at four-week intervals. Imaging revealed a stable membrane with no leakage. Five months after the third injection, OCT revealed intraretinal fluid. OCT-A showed a new branch of the neo-vascular membrane at the superficial capillary plexus. Following an additional ranibizumab injection, the membrane stabilized.

Conclusions and importance: It is conceivable that neovascularization developed due to, or in close conjunction with an epiretinal membranes already in place.
