[4] Hypertensive retinopathy is commonly considered a diagnostic feature of a hypertensive emergency although it is not invariably present. [5]
Hypertensive retinopathy with AV nicking and mild vascular tortuosity. Hypertensive retinopathy is a condition characterized by a spectrum of retinal vascular signs in people with elevated blood pressure. [57] It was first described by Liebreich in 1859. [58]
Arterial tortuosity syndrome exhibits autosomal recessive inheritance, and the responsible gene is located at chromosome 20q13. [ 6 ] [ 2 ] The gene associated with arterial tortuosity syndrome is SLC2A10 and has at least 23 mutations in those individuals found to have the aforementioned condition.

Other symptoms accompanying a hypertensive crisis may include visual deterioration due to retinopathy, breathlessness due to heart failure, or a general feeling of malaise due to kidney failure. [3] Most people with a hypertensive crisis are known to have elevated blood pressure, but additional triggers may have led to a sudden rise. [4]
Hyperviscosity syndrome is a group of symptoms triggered by an increase in the viscosity of the blood. Symptoms of high blood viscosity include spontaneous bleeding from mucous membranes , visual disturbances due to retinopathy , and neurologic symptoms ranging from headache and vertigo to seizures and coma .
Retinal vasculopathy with cerebral leukocencephalopathy and systemic manifestations (RVCL or RVCL-S, also previously known as retinal vasculopathy with cerebral leukodystrophy, RVCL; or cerebroretinal vasculopathy, CRV; or hereditary vascular retinopathy, HVR; or hereditary endotheliopathy, retinopathy, nephropathy, and stroke, HERNS) is an inherited condition resulting from a frameshift ...
