Cilioretinal artery occlusion (CiRAO) represents the rarest type of retinal vascular disease accounting for less than 10% of retinal arterial occlusions. They can occur isolated, in conjunction with a CRVO, or associated with arteritic ischemic optic neuropathy from giant cell arteritis. When isolated, a collagen vascular disorder may be present. Patients typically report an acute, painless central scotoma or decrease in central visual acuity. When isolated or associated with CRVO, they have a generally good prognosis for at least partial visual recovery.
There is localized retinal whitening due to inner retinal edema corresponding to the distribution of the cilioretinal artery (Fig. 15.3.1), which is only present in 20–30% of individuals.
