OCT revealed serous macular detachment (SMD) in the right eye. Optical coherence tomography angiography (OCTA) confirmed the presence of microaneurysms, ischemia, and capillary drop-out on the macula (Fig. 1).
Fundus fluorescein angiography showed multiple microaneurysms with surrounding ischemia in the early stage and leakages in the late stage in both eyes.

Fundus fluorescein angiography (FFA) revealed multiple microaneurysms with surrounding ischemia and leakages corresponding to microaneurysms (Fig. 2).
Optical coherence tomography images of a patient with radiation retinopathy and related macular edema. (a, b) Note that before injection of intravitreal ranibizumab, presence of cystoid macular edema (CME) in both eyes and serous macular detachment (SMD) in the right eye. Central macular thickness (CMT) was 392 mum (including 205 mum subretinal fluid) in right and 501 mum in the left eye. (c, d) After four times injections of ranibizumab, persistent CME and presence of bilateral SMD were present. CMT was 355 mum (including 109 mum subretinal fluid) in right and 522 mum (including 188 mum subretinal fluid) in the left eye. (e, f) After implantation of intravitreal dexamethasone implant, the disappearance of CME and normalization of foveal contour in both eyes. CMT was 183 mum in right and 197 mum in the left eye.

One month after injection, BCVA was 20/80 in both eyes and OCT showed normal foveal contour and no macular edema (Fig. 3).
