Amaurosis
Amaurosis (from ancient Greek ἀμαύρωσις - “darkening”) is partial or complete blindness, not associated with eye pathology.
In amaurosis, visual perception is impaired due to damage to the optic nerve, visual pathways, or visual cortex. The eyes seem outwardly healthy, but the person cannot see or sees very poorly.
One of the types of amaurosis is passing blindness (amaurosis fugax) - a condition in which loss of vision is temporary. This is usually associated with spasm or thrombosis of blood vessels in the eye or brain.
Amaurotic is an adjective denoting an attitude towards amaurosis.
Amaurosis is a condition in which a person loses vision for a period of time, and then vision is restored. This can be due to various reasons such as eye fatigue, stress, poor lighting or even certain medical conditions.
