Content: Sometimes even eye movements are enough to induce a temporary loss of vision. Retinal migraine is a spasm of the artery leading into the eye which supplies the retina. This spasm can lead to a temporary black-out of vision on one side, and is fairly rare. Retinal Artery Occlusion (Central Retinal Artery Occlusion and Branch Retinal Artery Occlusion)
If a clot (embolus) breaks free from the wall of a blood vessel leading up the neck or to the eye, it can lodge in the retinal arteries causing an obstruction of blood flow to the eye, and a loss of vision. In some cases, the clot will rapidly dislodge, and the vision will return (Amaurosis fugax, discussed above). However, if the clot is large it may not dislodge, and the vision remains blacked-out. Usually this is painless, and the loss of vision is severe. The vision in this condition may be reduced to being completely unable to see light out of the affected eye. If the blood flow to the retina is interrupted for more than 1 1/2 hours (approximately), the vision may not return even if the clot breaks free and the circulation is restored. This condition may indicate risk for cardiac disease, and stroke.
