  2. Hypertensive retinopathy - Wikipedia

    en.wikipedia.org/wiki/Hypertensive_retinopathy

    The most widely used modern classification system bears their name. [4] The role of retinopathy grading in risk stratification is debated, but it has been proposed that individuals with signs of hypertensive retinopathy signs, especially retinal hemorrhages, microaneurysms and cotton-wool spots, should be assessed carefully. [4]

  3. Intraretinal microvascular abnormalities - Wikipedia

    Specialty. Ophthalmology. 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 ...

  4. Salus's sign - Wikipedia

    en.wikipedia.org/wiki/Salus's_sign

    hypertensive retinopathy. Salus's sign is a clinical sign in which deflection of retinal venules can be seen on fundoscopy occurring in patients with hypertensive retinopathy. [1] Arteriosclerosis causes shortening or lengthening of arterioles, which causes venules to be moved at points where arterioles and venules cross over.

  5. Retinopathy - Wikipedia

    en.wikipedia.org/wiki/Retinopathy

    Retinopathy, or retinal vascular disease, can be broadly categorized into proliferative and non-proliferative types. Frequently, retinopathy is an ocular manifestation of systemic disease as seen in diabetes or hypertension. [3] Diabetes is the most common cause of retinopathy in the U.S. as of 2008. [4] Diabetic retinopathy is the leading ...

  6. Complications of hypertension - Wikipedia

    en.wikipedia.org/wiki/Complications_of_hypertension

    Hypertensive retinopathy is a condition characterized by a spectrum of retinal vascular signs in people with elevated blood pressure. It was first described by Liebreich in 1859. [58] The retinal circulation undergoes a series of pathophysiological changes in response to elevated blood pressure. [59]

  7. Diabetic retinopathy - Wikipedia

    en.wikipedia.org/wiki/Diabetic_retinopathy

    Diabetic retinopathy. Often asymptomatic, but can cause spots in the eye and vision loss. Diabetic retinopathy (also known as diabetic eye disease ), is a medical condition in which damage occurs to the retina due to diabetes. It is a leading cause of blindness in developed countries. Diabetic retinopathy affects up to 80 percent of those who ...

  8. Arteriovenous nicking - Wikipedia

    en.wikipedia.org/wiki/Arteriovenous_nicking

    Arteriovenous nicking. Arteriovenous nicking, also known as AV nicking, is the phenomenon where, on examination of the eye, a small artery ( arteriole) is seen crossing a small vein ( venule ), which results in the compression of the vein with bulging on either side of the crossing. This is most commonly seen in eye disease caused by high blood ...

  9. Ocular hypertension - Wikipedia

    en.wikipedia.org/wiki/Ocular_hypertension

    Ocular hypertension. Ocular hypertension is the presence of elevated fluid pressure inside the eye ( intraocular pressure ), usually with no optic nerve damage or visual field loss. [ 1][ 2] For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [ 3][ 4] Elevated intraocular pressure is an important risk ...
