Central Retinal Artery Occlusion with Cilioretinal Artery Sparing

Central retinal artery occlusion with sparing of the cilioretinal artery Figure 1 : Fundus photographs show retinal whitening in the right eye, with sparing of the perfused retina in the distribution of the cilioretinal artery (arrows); the left eye has a normal funduscopic appearance. Figure 2 : Montage photograph of the right eye. CRAO with cilioretinal artery sparing (yellow arrow) Figure 3: Fundus photograph (A) and fluorescein angiography (B) of the right eye. There is "box-carring" seen in small branches of the central retinal artery (white arrows), corresponding to segmentation of the blood column on the fluorescein angiography (yellow arrows) Figure 4 : Retinal fluorescein angiography of the right eye shows a delay in the retinal arterial filling at 25 sec, 1 min, 1 min 51 sec, 3 min 33 sec, whereas the cilioretinal artery remains normally perfused (yellow arrows)
