Ocular ischemic syndrome is the constellation of ocular
signs and
symptoms secondary to severe, chronic
arterial hypoperfusion to the
eye.
Amaurosis fugax is a form of acute
vision loss caused by reduced blood flow to the eye that may be a warning sign of an impending
stroke. Consequently, those with transient blurring of vision are advised to urgently seek medical attention for a thorough evaluation of the
carotid artery.
Anterior segment ischemic syndrome is a similar ischemic condition of
anterior segment usually seen in post-surgical cases.
Retinal arterial occlusion leads to rapid death of retinal cells, thereby resulting in severe loss of vision.
