The lack of blood supply to the peripheral retina triggers the release of molecules that stimulate blood vessel growth, such as vascular endothelial growth factor (VEGF). However, this new blood vessel growth, also known as neovascularization , can lead to further complications such as the leakage and hemorrhage of retinal blood vessels ...
Eales disease is a type of obliterative vasculopathy, also known as angiopathia retinae juvenilis, periphlebitis retinae or primary perivasculitis of the retina.It was first described by the British ophthalmologist Henry Eales (1852–1913) in 1880 [1] and is a rare ocular disease characterized by inflammation and possible blockage of retinal blood vessels, abnormal growth of new blood vessels ...
In some patients the fluid remains, making it a chronic disease; medical therapy or the application of various laser methods is possible. In about 25% of all patients with a chronic central serous chorioretinopathy, a proliferation of blood vessels from the choroid towards the retina can be detected (choroidal neovascularisation, CNV).
Recently, central serous chorioretinopathy has been understood to be part of the pachychoroid spectrum. [5] [6] In pachychoroid spectrum disorders, of which CSR represents stage II, the choroid, the highly vascularized layer below the retina, is thickened and congested with increased blood vessel diameter, especially in the deep choroid (the so-called Haller's layer).
Both types cause disease by altering the normal blood flow to the retina through different mechanisms. The retina is supplied by small vessel branches from the central retinal artery. [8] Proliferative retinopathy refers to damage caused by abnormal blood vessel growth. [9] Normally, angiogenesis is a natural part of tissue growth and formation.
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 ...
For instance, one study found that people who ate soy foods, like tofu and natto, were less likely to develop cardiovascular disease or type 2 diabetes. In fact, eating as little as 1 ounce of ...
Intraretinal microvascular abnormalities (IRMA) are abnormalities of the blood vessels that supply the retina of the eye, a sign of diabetic retinopathy. [1] IRMA can be difficult to distinguish from and is likely a precursor to retinal neovascularization. One way to distinguish IRMA from retinal neovascularization is to perform fluorescein ...
