Electrophysiology Test Unit for ERG , VEP and EOG

Electrophysiology testing includes a battery of tests which can be used to provide information about the visual system beyond the standard clinical examination of the eye. Electroretinography (ERG) and Electro-oculography (EOG) are two of the tests conducted in the Ophthalmic Electrophysiology Laboratory. The primary objective of the electrophysiologic examination is to assess the function of the visual pathway from the photoreceptors of the retina to the visual cortex of the brain. Information obtained from these diagnostic tests helps establish the correct diagnosis or may rule out related ophthalmic diseases.

Electrophysiologic testing is useful in diagnosing a variety of inherited retinal and optic nerve diseases, toxic drug exposure, inflammatory conditions, intraocular foreign bodies, and retinal vascular occlusions. Electrophysiologic testing is performed most often in large referral centers which have expertise in obtaining and interpreting these data. The data are used in conjunction with the clinical examination and other tests (perimetry, dark adaptometry) to establish a correct diagnosis.
