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. A cilioretinal artery has been found to be present in 49.5% of ...

2020年4月14日 · DISCUSSION Introduction Retinal artery occlusion occurs when an artery in the retina is blocked, most commonly due to emboli. Occlusion of the central retinal artery (CRAO), a branch of the central retinal artery (BRAO), or the cilioretinal artery (CLRAO) may occur.

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.

2020年6月10日 · SD-OCT imaging of the macula of the left eye revealed diffuse hyper-reflective bands along the inner nuclear layer (INL), a finding that is typical of paracentral acute middle maculopathy (PAMM).

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].

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 drove directly to his optometrist. The optometrist documented visual acuities of 20/40 OD and light perception (LP) vision OS. It was noted that the ...

2007年8月14日 · Differential Diagnoses for appearance of Optic Nerve Drusen Note: Optic nerve head drusen are usually an independent finding, but can be related to other conditions, such as pseudoxanthoma eleasticum (PXE), retinitis pigmentosa, and angioid streaks. Glaucoma and other causes for visual field loss must be considered when field loss is suspected due to optic nerve drusen. Consideration of the ...

Contributor: Jesse Vislisel, MD, The University of Iowa 71-year-old woman presenting with a cilioretinal artery occlusion. On OCT, there is inner retinal thickening and blurring of retinal layers due to edema.

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.
