Electrophysiology's role in early detection of glaucoma
An office-based system (NOVA Testing System, Diopsys) represents an advance in electrophysiological technology that allows clinicians the ability to detect pathology they have been unable to see in the past, thereby detecting disease early.

The only characteristics
Historically, visual evoked potentials (VEP) and electroretinography (ERG) tests have been in use in research facilities to analyze the functional integrity of the neuro-visual pathway. Though the information from these tests was always considered valuable, the nature of the testing made it impractical to integrate into everyday clinical practice.
VEP and ERG testing equipment used to be bulky, expensive, and fragile, and the extensive data generated required a neurophysiologist to decipher the results. ERG tests required sensors to be placed directly on the patient’s eye and remain there for 45 to 50 minutes, creating a long and invasive exam.
