Amaurotic nystagmus
Amaurotic Nystagmus
Amaurotic nystagmus (pronunciation: am-aw-rot-ik nis-tag-mus) is a medical term referring to a specific type of nystagmus, which is characterized by involuntary, rapid, and rhythmic eye movements. This condition is often associated with amaurosis, a state of vision loss or blindness, particularly when it is not caused by any apparent damage to the eye itself.
Etymology
The term "amaurotic nystagmus" is derived from two Greek words. "Amaurosis" (Greek: αμαύρωση) means darkening or obscuring, which refers to the loss of vision. "Nystagmus" (Greek: νυσταγμός) means nodding or drowsiness, which describes the involuntary eye movements.
