Figure 2: The sequential optical coherence tomography during the treatment. (a) Optical coherence tomography showed improved macular edema after 1^st injection of aflibercept with central retinal thickness of 312 μm. (b) Optical coherence tomography showed recurrent cystoid macular edema 2 month after 1^st injection of aflibercept with central retinal thickness of 363 μm. (c) Optical coherence tomography showed improved macular edema the next month after 2^nd injection of aflibercept with central retinal thickness of 301 μm. (d) Optical coherence tomography showed recurrent cystoid macular edema and subretinal fluid 3 months after 2^nd injection of aflibercept with central retinal thickness of 363 μm
