🧠 What is a VEP Test?

Visual Evoked Potentials (VEP) is a painless, non-invasive neurological test that measures the brain’s response to visual stimuli, typically flashes of light or checkerboard patterns.

Small electrodes are placed on the scalp, and as the patient views the visual screen, the system records how quickly and effectively visual signals travel from the eye to the brain.

The VEP test is used to evaluate:

  • Optic nerve damage

  • Multiple sclerosis (MS)

  • Unexplained vision loss

  • Visual pathway tumors or injuries

  • Pediatric visual development issues

🧪 How the VEP Test Works

The test takes 30–45 minutes and is safe for both adults and children.

The Procedure:

  1. Electrodes are placed on your scalp (typically at the back of the head).

  2. You’ll look at a screen with checkerboard patterns or flashing lights.

  3. The brain’s responses are recorded to see how quickly visual information travels from the eyes to the visual cortex.

No dilation, injections, or special preparation is needed.

Testimonials

Patient Voices
I had blurry vision that glasses couldn’t fix. VEP showed delayed optic nerve signals, leading to my MS diagnosis. The test was simple and informative.
Parent of a 3-month-old
My son had poor eye tracking despite a normal eye exam. The VEP revealed underdeveloped visual pathways, and now he’s in early therapy.
— Ravi K., Parent
Post-surgery, I had one-sided vision loss. VEP confirmed the nerve was intact. It gave me hope.
— Sujata D., 47
