Amaurosis fugax is a temporary loss of vision in one or both eyes due to a lack of blood flow to the retina. The retina is the light-sensitive layer of tissue at the back of the eyeball. Amaurosis fugax is not itself a disease. Amaurosis fugax can occur from different causes. When a blood embolism or an item of plaque obstructs an artery in the eye, one cause is. The blood embolism or plaque usually travels from a larger artery, such as the carotid artery in the neck or an artery in the heart, to an artery in the eye. Some people explain the loss of vision as a grey or black color coming down over the eye.
