Central retinal artery occlusion (CRAO) occurs when occlusion of the central retinal artery, a branch of the ophthalmic artery, results in infarction of the inner retina with subsequent, typically severe, vision loss. The picture above exhibits a CRAO with sparing of the foveal retina due to the presence of a cilioretinal artery.

2020年4月14日 · CRAO and BRAO are rare entities. The incidence of CRAO is between 1-2 persons per 100,000 per year [3] while the incidence of BRAO is closer to 5 per 100,000 persons per year [2]. Retinal artery occlusion can occur in patients of …

2018年7月20日 · OCT-A may also be used to further characterize choroidal NV that occurs as a complication of disorders that cause retinal hypoxia (Figure 5C). Goldmann perimetry is not routinely performed in patients with BRVO but may reveal arcuate scotomas, central scotomas, paracentral scotomas, and segmental peripheral constriction.

2018年5月22日 · Less common entities that cause retinal ischemia, and subsequently NVG, include central retinal artery occlusion (CRAO), sickle cell retinopathy, radiation retinopathy, retinopathy of prematurity, and carotid-cavernous sinus fistulas [2, 11]. Regardless of the underlying etiology, posterior segment ischemia results in disequilibrium between ...

2005年2月21日 · Central Retinal Artery Occlusion (CRAO): 81 year-old white male with sudden, painless vision loss in left eye. patient described a sudden black spot in his vision that spread out over his complete visual field OS over a 15-minute time frame. He …

2007年8月14日 · Some have suggested that OCT may be helpful to quantify any degree of nerve fiber loss with satisfying reproducibility (Auw-Haedrich 2002). Complications As optic nerve drusen enlarge, they can compress and compromise nerve fibers and the vascular supply, leading to multiple complications including visual field defects, vascular occlusion, and ...

Optociliary shunt vessels are collateral vessels connecting the choroidal and the retinal vasculature. The differential diagnosis for acquired optociliary shunt vessels commonly includes central retinal vein occlusion, chronic glaucoma, chronic …

2018年2月7日 · His exam and testing were consistent with a combined central retinal vein occlusion (CRVO) and central retinal artery occlusion (CRAO), secondary to proliferative radiation retinopathy. He underwent bevacizumab injections and several sessions of panretinal photocoagulation to try to prevent neovascular glaucoma.
