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 …

Intraretinal microvascular abnormalities (or IrMAs) are shunt vessels and appear as abnormal branching or dilation of existing blood vessels (capillaries) within the retina that act to supply areas of non-perfusion in diabetic retinopathy.

2018年7月20日 · Superotemporal sclerotic vessels were present. There was an area suspicious for an inferotemporal retinal arterial macroaneurysm in the mid-periphery. C-D. OCT showed improvement of subretinal fluid, but there was still persistence of intraretinal fluid when comparing the initial (C) and most recent (D) OCT images.

2017年9月26日 · A carotid-cavernous fistula (CCF) is a pathologic shunt between the carotid artery and the venous cavernous sinus; such hemodynamic lesions often lead to the triad of exophthalmos, epibulbar arterialized loops, and glaucoma. Diagnosis is by clinical examination, computed tomography or magnetic resonance angiography, and/or catheter angiography.

2014年9月29日 · Chronically sclerotic and deranged retinal vessels can be observed in end-stage disease. Approximately 5% of patients develop neovascular glaucoma [5,12]. Systemic manifestations

Wyburn-Mason syndrome (racemose hemangiomatosis) is a non-hereditary, unilateral condition characterized by retinal arteriovenous malformations composed of dilated, tortuous vessels which shunt blood between arteries and veins.

2018年5月22日 · Aqueous shunts (e.g., Ahmed shunt) provide the advantage of avoiding a surgical iridectomy and are more likely to tolerate perioperative bleeding and massive fibrin reaction. Surgeons may opt to place the tube in the sulcus behind the iris in an attempt to protect the tube from NVG-associated fibrovascular membranes and to protect the cornea.
