Patient with a reperfused cilioretinal artery-occlusion. Initial optical coherence tomography showed a diffuse swelling of the inner retina layers of the upper macular region (A, B). Optical coherence tomography at day 4 revealed no increase in edema (C, D). Optical coherence tomography angiography on day 10 depicts regular vascular structure in all three vascular plexuses (E). After 6 weeks, the retinal edema turned into atrophy (F, G) with thinning of inner nuclear layer and outer plexiform layer (H, orange arrows in F and H). This resulted in reduction of perfusion exclusively in the deep capillary plexus, located in the inner nuclear layer and outer plexiform layer. The superficial vascular plexus and intermediate capillary plexus were not affected (I). While there was progression of the retinal atrophy after 6 months (J–L), especially of the inner nuclear layer and outer plexiform layer (orange arrows in J and L, there was no progression of the perfusion defects on optical coherence tomography angiography (M)
