Optical coherence tomography showed no evidence of macular edema (Figure 2 (Fig. 2)). 
Fluorescein angiogram showing significantly delayed arterial filling with 60 seconds in the right eye (A) and 52 seconds in the left eye (B) and poor peripheral perfusion. Arteries are attenuated and veins are dilated and non-tortuous in both eyes. The late film (C) shows mild capillary leakage in the right eye at 6 minutes but no macular edema or neovascularization.

Fluorescein angiography exhibited delayed arterial filling and poor peripheral perfusion (Figure 3 (Fig. 3)).
MRA extracranial showing severe narrowing of the origin of the right brachiocephalic artery (yellow arrow) and complete occlusion of the left common carotid artery with distal reconstitution of flow near the bifurcation (red arrow).
