Transient Vision Loss

Abstract

Transient vision loss often presents a diagnostic dilemma and may occur in many different settings. Episodic vision loss is a common complaint and the physician must distinguish whether the transient vision loss is benign or representative of a more serious underlying condition. Common causes of transient vision loss include ischemia and primary ocular pathology. Ischemic causes of vision loss include retinal vascular disease, intermittent optic nerve vascular compromise, or cerebrovascular disease. Many pathologic ocular processes may lead to transient vision loss, including tear film abnormalities and corneal diseases. The authors discuss the clinical presentation and management of transient vision loss, with special attention on characteristics that differentiate vascular disease from primary ocular pathology.
