What is Fundi for hypertensive retinopathy?
Funduscopic examination shows arteriolar constriction, arteriovenous nicking, vascular wall changes, flame-shaped hemorrhages, cotton-wool spots, yellow hard exudates, and optic disk edema. Treatment is directed at controlling blood pressure and, when vision loss occurs, treating the retina.
What are the fundus changes in a hypertensive?
Hypertensive retinopathy causes vascular constriction of retinal arterioles and typical fundus findings, such as blot hemorrhages, hard exudates and cotton wool spots resulting from ischemia within the nerve fiber layer.
What are the two most common findings with hypertensive retinopathy?
Common hypertensive retinal changes are flame-shaped hemorrhages in the superficial layers of the retina and cotton-wool patches caused by occlusion of the precapillary arterioles with ischemic infarction of the inner retina.
What is blood and thunder fundus?

Using an ophthalmoscope, an instrument that projects light to examine the back of the eyeball, the doctor will look for signs of retinopathy that include: Narrowing of blood vessels. Spots on the retina known as cotton wool spots and exudates.
Does hypertensive retinopathy have neovascularization?
Retinal neovascularization attributed to hypertensive retinopathy is rarely reported in the literature. The diagnosis should be considered only after performing a thorough evaluation to exclude more common causes of proliferative retinopathy.
What causes cherry red spot?
The appearance of a cherry red spot can result from retinal edema most commonly due to central retinal artery occlusion or traumatic retinal ischemia, which cause the perimacular tissue of the retina to appear translucent, while the fovea maintains its normal color.
