Visual electrophysiology is the technique involved for recording numerous electrical signals from brain, optic nerve and eye in response to the visual stimuli. The electrophysiological responses are varied in different ways according to the disease progressions affecting the optic nerve, retina and visual pathways. Visual electrophysiological tests are performed with its wide range of application involving diagnosis, locating problem at some level of visual system, elimination of specific conditions, valuation of visual system maturity level in pre literate child, monitoring the progress of known condition and provision of an estimated objective measure of visual insight. The visual electrophysiology testing devices can be used for children, adults or animals of all sizes for clinical and research purpose.
The International Society for Clinical Electrophysiology of Vision (ISCEV) decides and regularly review the standards for recording all the common electrophysiological tests and are benchmarked for all visual electrophysiology services. The visual electrophysiology tests are non invasive and are performed to detect functional information about the retina and optic nerve and also allow the diagnosis of some disorders relating to retina and brain. The most common visual electrodiagnostic test is electroretinogram (ERG). The Information collected from these diagnostic tests help in establishing the correct diagnosis or is helpful to rule out related ophthalmic diseases.

Visual Electrophysiology Testing Devices Market: Overview
Visual electrophysiology testing is performed according to the disorder. On the basis of test type, electroretinogram and visual-evoked responses are the most widely used test in the visual electrophysiology respectively. An ERG is advantageous in evaluating both hereditary (inherited) and acquired disorders of the retina. The diagnoses commonly suspects the predominant conditions of the retina including retinitis pigmentosa,retinitis pigmentosa sine pigmento,, choroideremia,, achromatopsia,and congenital stationary night blindness. The increasing government initiatives for the early diagnosis and treatment of visual and neurological disorders are expected to upsurge the overall visual electrophysiology testing device market.
