Branch retinal artery occlusion (BRAO) is a rare retinal vascular disorder in which one of the branches of the central retinal artery is obstructed. [ 1 ] Signs and symptoms
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Branch retinal vein occlusion revealed by laser Doppler imaging through flow alteration in the upper right branch artery. The diagnosis of branch retinal vein occlusion is made clinically by finding retinal hemorrhages in the distribution of an obstructed retinal vein. Fluorescein angiography is a helpful adjunct. Findings include delayed ...
Hollenhorst plaques may cause retinal occlusion, where the plaque blocks blood flow through the retinal vessels, resulting in temporary or permanent vision loss in the affected eye. [1] However, while Hollenhorst plaques do become lodged in retinal arteries, they generally do not fully prevent blood flow so do not cause ischemia. [1]
Central retinal artery occlusion: CRAO is characterized by painless, acute vision loss in one eye. [11] Central retinal vein occlusion: CRVO causes sudden, painless vision loss that can be mild to severe. [12] Branch retinal vein occlusion: sudden painless vision loss or visual field defect are the main symptom of BRVO. [13]
Causes This condition is ... Other conditions causing rubeosis iridis include central retinal vein occlusion, [2] ocular ischemic syndrome, [3] and chronic retinal ...
Lipaemia retinalis is a retinal disease caused by hypertriglyceridemia or chylomicronemia. [3] Depending on plasma triglyceride level, the retinal arteries, veins or occasionally the entire fundus may show creamy-white to salmon red discoloration. [6] In primary hyperlipidaemia, LR occurs only in patients with increased chylomicron levels. [6]
Retinal vasculitis is inflammation of the vascular branches of the retinal artery, caused either by primary ocular disease processes, or as a specific presentation of any systemic form of vasculitis such as Behçet's disease, sarcoidosis, multiple sclerosis, or any form of systemic necrotizing vasculitis such as temporal arteritis, polyarteritis nodosa, and granulomatosis with polyangiitis, or ...
