Functional Testing in Glaucoma Diagnosis

Abstract

The glaucomas are a group of diseases characterized by progressive optic neuropathy, often leading to partial or complete vision loss. Early recognition and careful monitoring for disease advancement are critical for prevention of vision loss. Frequently, asymptomatic defects in the patient’s field of vision are key elements to diagnosis. Thus, it is important that the ophthalmologist stay informed regarding tools available for visual field assessment. This review will discuss the current functional testing modalities for glaucoma evaluation.
