Abstract

Glaucoma is an optic neuropathy characterized by retinal ganglion cells (RGC) degeneration associated with visual field defects. Though conventional structural and functional assessments, such as optical coherence tomography (OCT) and perimetry, are essential for diagnosis, clinical electrophysiology of vision can offer a valuable understanding of the pathophysiology of the glaucomatous damage. This article highlights the role of electrophysiological testing in early detection of glaucoma and monitoring disease progression.
