Figure 1: 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 × 6 mm retina slab reveals absent flow similar to that seen on FA. (e) OCT-A 6 × 6 mm superficial slab reveals absent flow. (f) OCT-A 6 × 6 mm deep slab reveals absent flow.
