Overview
Amaurosis (Greek meaning darkening, dark, or obscure) is vision loss or weakness that occurs without an apparent lesion affecting the eye [2]. It may result from either a medical condition or from excess acceleration, as in flight. The term is the same as the Latin gutta serena.
Types
Leber's congenital amaurosis is an inherited disease resulting in severe vision loss or blindness that was first described by Theodore Leber in the 19th century.
This condition can also occur in ruminants suffering from a vitamin B1 (Thiamin) deficiency due to Thiamine-Related Cerebrocortical Necrosis (CCN).
Management
Those experiencing amaurosis are usually advised to consult a physician immediately as any form of vision loss, even if temporary, is a symptom that may indicate the presence of a serious ocular or systemic problem.
