Aug 1, 2017 · Central retinal artery occlusion (CRAO) is an ocular emergency. Patients typically present with profound, acute, painless monocular visual loss—with 80% of affected indi­viduals having a final visual acuity of counting fingers or worse.

Mar 8, 2021 · An ophthalmological evaluation including a dilated funduscopic examination or a nonmydriatic color fundus photograph is necessary to confirm the diagnosis of CRAO and rule out other disorders that can cause acute painless loss of vision, including vitreous and chorioretinal hemorrhage, retinal detachment, and acute optic neuropathy.

May 2, 2024 · Central retinal artery occlusion (CRAO) is an ophthalmic emergency that can lead to sudden and severe vision loss. CRAO has been defined as interruption of blood flow through the central retinal artery by thromboembolism or vasospasm with or without retinal ischemia.

CRAO can be easily diagnosed by fundoscopic examination, and timely treatment is crucial for the alleviation of CRAO (5 – 8). In the present study, the fundus fluorescein angiography (FFA) results of CRAO patients attending the Tianjin Eye Hospital (Heping, China) were …

Ophthalmoscopic fundus findings in central retinal artery occlusion (CRAO), in 240 consecutive patients (248 eyes), showed that it is essential to classify CRAO into 3 types: permanent CRAO, permanent CRAO with cilioretinal artery sparing, and transient CRAO.

Visual acuity testing, evaluation for an afferent pupillary defect, funduscopic examination, and fluorescein angiography (FA) remain the mainstay tools for diagnosing central retinal artery occlusion.

Central retinal artery occlusion occurs when the central retinal artery becomes blocked, usually due to an embolus. It causes sudden, painless, unilateral, and usually severe vision loss. Diagnosis is by history and characteristic retinal findings on funduscopy.

Apr 10, 2024 · Purpose: To characterize features of central retinal artery occlusion (CRAO) using multicolor (MC) imaging and to assess the differences in CRAO grading between color fundus photography (CFP) and MC image qualitatively and quantitatively.

Typical central retinal artery occlusion with cherry-red spot, retinal edema and narrowing of the vessels. ↑ Miller N, Newman N. Walsh & Hoyt’s Clinical Neuro-ophthalmology. 5th Edition. Baltimore: Williams and Wilkins 1998. pp. 3758-9. ↑ Hayreh SS. …

In acute CRAO, the choroid underlying the macula—the thinnest part of the retina—produces a dark orange-red color, described as a ‘cherry red spot’, against the pale retina (Figure 1B). Other signs in the affected eye include an afferent pupillary defect relative to the unaffected eye and a visual field defect.
