Answer

Central retinal artery occlusion (CRAO) was first described by Van Graefe in 1859 as an embolic event to the central retinal artery in a patient with endocarditis. In 1868, Mauthner suggested that “spasmodic contractions” could lead to retinal artery occlusion. CRAO has various causes, but patients typically present with sudden, severe, and painless loss of vision.
