  2. Ocular ischemic syndrome - Wikipedia

    en.wikipedia.org/wiki/Ocular_ischemic_syndrome

    Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...

  3. Brain ischemia - Wikipedia

    en.wikipedia.org/wiki/Brain_ischemia

    Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.

  4. Carotid artery stenosis - Wikipedia

    en.wikipedia.org/wiki/Carotid_artery_stenosis

    The internal carotid artery supplies the brain, and the external carotid artery supplies the face. This fork is a common site for atherosclerosis, an inflammatory build-up of atheromatous plaque inside the common carotid artery, or the internal carotid arteries that causes them to narrow. [3] [4]

  5. Vaso-occlusive crisis - Wikipedia

    en.wikipedia.org/wiki/Vaso-occlusive_crisis

    A vaso-occlusive crisis is a common painful complication of sickle cell anemia in adolescents and adults. [1] [2] It is a form of sickle cell crisis.Sickle cell anemia – most common in those of African, Hispanic, and Mediterranean origin – leads to sickle cell crisis when the circulation of blood vessels is obstructed by sickled red blood cells, causing ischemic injuries.

  6. Watershed stroke - Wikipedia

    en.wikipedia.org/wiki/Watershed_stroke

    Diseases such as sickle cell anemia, which can lead to deformed red blood cells clogging blood vessels and impeding blood flow [9] Carotid artery stenosis, or narrowing of the carotid artery which can decrease the volume of blood flow to the brain [8]

  7. Sickle cell disease - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_disease

    Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders that are typically inherited. [2] The most common type is known as sickle cell anemia. [2] Sickle cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]

  9. Amaurosis fugax - Wikipedia

    en.wikipedia.org/wiki/Amaurosis_fugax

    The most common source of these athero-emboli is an atherosclerotic carotid artery. [11] However, a severely atherosclerotic carotid artery may also cause amaurosis fugax due to its stenosis of blood flow, leading to ischemia when the retina is exposed to bright light. [12] "Unilateral visual loss in bright light may indicate ipsilateral ...
