Transient blindness: Temporary loss of vision usually lasting less than 5 minutes often as a result of a small blood clot (embolus) passing through the retinal artery.
Dr. Tim Conrad

Amaurosis fugax: Amaurosis fugax is a temporary loss of vision caused by blockage of blood flow in the eye from a small blood clot or cholesterol piece. It is typically a darkening of the vision that lasts 20-30 minutes. People have amaurosis fugax are at high risk to have a stroke in the near future.

Amaurosis fugax: This is classically described as noting a curtain like interruption going across the line of vision this is side to side and is temporary and should clear shortly. It is a sign of potential impending stroke and needs immediate evaluation. If it is up and down rather than side to side then it is a sign of impeded posterior brain circulation. This is not amaurusis fugax but just as dangerous.
