case_images: Acute central retinal artery occlusion, left eye. (a) Fundus photography reveals macular drusen and mild macular whitening with an early cherry red spot. (b) Spectral domain optical coherence tomography (SD-OCT) reveals thickening and hyperreflectivity of the inner retinal layers. (c) Fluorescein angiography (FA) at 26.58 seconds reveals delayed retinal perfusion. (d) Optical coherence tomography angiography (OCT-A) 6 x 6 mm retina slab reveals absent flow similar to that seen on FA. (e) OCT-A 6 x 6 mm superficial slab reveals absent flow. (f) OCT-A 6 x 6 mm deep slab reveals absent flow.

case_images: Fundus examination revealed macular drusen as well as mild macular whitening and an early cherry red spot (Figure 1(a)). SD-OCT demonstrated thickening and hyperreflectivity of the inner retinal layers (Figure 1(b)). FA at 26.58 seconds revealed delayed retinal perfusion (Figure 1(c)). The OCT-A retina slab (Figure 1(d)), superficial slab (Figure 1(e)), and deep slab (Figure 1(f)) revealed absent flow very similar to the FA.

case_images: Acute central retinal artery occlusion with cilioretinal sparing, left eye. (a) Fundus photography reveals macular whitening with cilioretinal artery sparing. (b) Spectral domain optical coherence tomography (SD-OCT) reveals macular thickening and hyperreflectivity of the inner retinal layers temporal to the center of the macula, consistent with cilioretinal artery sparing. (c) Fluorescein angiography (FA) at 18.67 seconds reveals delayed retinal perfusion with cilioretinal artery sparing. (d) Optical coherence tomography angiography (OCT-A) 6 x 6 mm retina slab reveals absent flow similar to that seen on FA. There is diminished signal superiorly due to artifact. (e) OCT-A 6 x 6 mm superficial slab reveals absent flow. There is diminished signal superiorly due to artifact. (f) OCT-A 6 x 6 mm deep slab reveals absent flow. There is diminished signal superiorly due to artifact.

case_images: Fundus examination revealed macular whitening in a pattern consistent with CRAO with cilioretinal artery sparing (Figure 2(a)). SD-OCT demonstrated thickening and hyperreflectivity of the inner retinal layers temporal to the center of the macula (Figure 2(b)). FA at 18.67 seconds revealed delayed retinal perfusion consistent with the pattern of macular whitening (Figure 2(c)). The OCT-A retina slab (6 x 6 mm) revealed absent flow in the same distribution as the FA (Figure 2(d)).
