Amaurosis fugax
Amaurosis fugax (pronounced: am-aw-ROH-sis FYOO-gaks) is a medical term that refers to a temporary loss of vision in one or both eyes. This condition is usually brief, lasting only a few seconds to a few minutes. It is often a warning sign of an impending stroke or other serious circulatory problem.
Etymology
The term "Amaurosis fugax" comes from the Greek words "amaurosis," meaning darkening, dimming or loss of sight, and "fugax," a Latin word meaning fleeting or transient.
Symptoms
The primary symptom of Amaurosis fugax is a sudden, temporary loss of vision. This can occur in one or both eyes and can last from a few seconds to a few minutes. Other symptoms may include blurred vision, double vision, or flashing lights in the visual field.
Causes
Amaurosis fugax is often caused by a blockage or clot in the blood vessels that supply the eye. This can be due to a number of conditions, including atherosclerosis, hypertension, diabetes, and certain heart conditions. It can also be a symptom of a transient ischemic attack (TIA), which is often a warning sign of a future stroke.
Treatment
Treatment for Amaurosis fugax focuses on addressing the underlying cause of the condition. This may involve medications to reduce blood clotting, surgery to remove blockages in the blood vessels, or lifestyle changes to manage conditions like diabetes or hypertension.
