CRVO, nonischemic, with macular edema

Images of the fundus of an eye with a nonischemic central retinal vein occlusion (CRVO) with macular edema. A - Red free fundus photograph shows intraretinal hemorrhages and dilated veins in all four quadrants. B - Frame from the early venous phase of the fluorescein angiogram shows good capillary perfusion as was present peripherally as well (not shown), thus this CRVO is nonischemic. C - Frame from the late phase fluorescein angiogram shows insignificant disk hyperfluorescence (orange arrow), corresponding to the absence of disk edema, and the presence of cystoid macular edema (yellow arrow). D - Line scan from the spectral domain optical coherence tomography study shows macular edema (central subfield mean thickness = 519 μ) with morphologic cysts (yellow arrow) that correspond to the petalloid cysts on the fluorescein angiogram and subretinal fluid (orange arrow) that could not be appreciated clinically.
