Visual evoked potential testing is a type of neurophysiologic study. The test involves placing electrodes on the patient’s scalp. Then, we measure the electric response to a visual stimulus along the optic nerve as the signal travels through the brain.

Clinical functions of visual evoked potential testing include the following

• earlier and more accurate diagnosis of glaucoma
• earlier and more accurate diagnosis of other optic nerve diseases
• earlier and more accurate diagnosis of amblyopia
• assist in the diagnosis and treatment of multiple sclerosis

Visual evoked potential testing may be indicated in the following clinical situations

• glaucoma
• glaucoma suspect
• other optic neuropathy
• multiple sclerosis
• visual disturbances
• intracranial injury
• irregular eye movements
