The Characteristics of Retinal Emboli and its Association With …
Results: There were 52/248 (21%) eyes with RAO and visible retinal emboli (31/187 [17%] eyes with CRAO and 21/61 [34%] eyes with BRAO) showing various embolic features. Platelet-fibrin emboli were observed most commonly, and showed the earliest and highest rate of movement.
Retinal Artery Occlusion - EyeWiki
A symptomatic retinal artery occlusion is an ophthalmic emergency that requires immediate evaluation and transfer to a stroke center. It is an obstruction of retinal blood flow that may be due to an embolus causing occlusion or thrombus formation, vasculitis causing retinal vasculature inflammation, traumatic vessel wall damage, or spasm.
Assessing Patients with Asymptomatic Retinal Emboli Detected at Retinal …
Here we propose a pathway for the investigation and management of individuals with diabetes found to have retinal emboli on annual retinal screening. This pathway enables the identification of individuals eligible for surgical intervention before a cerebrovascular event occurs.

Jan 11, 2024 · Hollenhorst plaques, named after the American ophthalmologist Robert Hollenhorst, are microscopic cholesterol emboli that can be found in the small blood vessels of the retina.
Central Retinal Artery Occlusion and Branch 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.
Blockage of Central Retinal Arteries and Branch Retinal Arteries
The central retinal artery is the main vessel that supplies blood to the retina. This artery can become completely blocked by an embolism or thrombosis (formation of a blood clot in the artery). Blockage may occur in the main artery or in its branches. (See also Overview of …
