Brief Loss of Vision in One Eye
Medical practitioners refer to the temporary loss of vision in one eye as amaurosis fugax. The condition can persist for seconds to minutes; doctors also term it episodic blindness. However, sudden blindness, even in one eye, shouldn’t be treated lightly as it can indicate a more serious medical condition such as a stroke or progressive eye injury.
According to doctors, the most common cause of amaurosis fugax is reduced blood flow to the eye. Every individual has a set of large blood vessels in their neck that bring blood from the heart to the eyes and the brain. If plaque buildup happens within those arteries, and if the plaque breaks off and lodges itself near the eye, amaurosis fugax can manifest. When the blood vessels become too narrow, and the blood supply doesn’t suffice the needs of the eye, temporary blindness could happen. While it isn’t painful and only occurs quickly, it can still signify an underlying medical condition.
Treating amaurosis fugax depends on the underlying reason. For example, doctors can prescribe blood thinners or aspirin to prevent blood clots. They can also prescribe medication to control hypertension, diabetes, and hyperlipidemia. Lifestyle changes such as alcohol and smoking abstinence will also help.
