Visual Evoked Potentials (VEP)

Visual Evoked Potentials (VEP) at Sheikh Shakhbout Medical City, Abu Dhabi

The neurology division at Sheikh Shakhbout Medical City (SSMC) offers advanced neuro-diagnostic services including Visual Evoked Potentials (VEP) to assist in the assessment and monitoring of visual pathway and neurological disorders.

What is VEP?

VEP is a non-invasive electrophysiological test that measures electrical activity in the brain in response to visual stimuli. It helps assess the integrity of the visual pathways from the eye to the visual cortex.

When is VEP Used?

At SSMC, VEP is used in the context of:

• Demyelinating conditions such as multiple sclerosis
• Visual disturbance where structural imaging alone is insufficient
• Neuromuscular or nerve disorders that may affect vision
• Monitoring progress or response to treatment in neurological conditions

How is the Test Performed?

• The patient sits comfortably and watches a repeating visual stimulus (e.g., a pattern or flashing light)
• Electrodes are placed on the scalp, and responses are recorded over a short period
• The test is painless, takes around 20 to 30 minutes, and does not require sedation in most adult cases

What the Results Show

• Delayed conduction or reduced amplitude of responses may indicate impairment of the visual pathway
• The neurologist interprets the results in combination with clinical findings and imaging

Why Choose SSMC for VEP?

• Board-certified neuropathologists and neurologists working in a multidisciplinary team with imaging and diagnostics
• Modern electrophysiology laboratory and integrated diagnostic services
• Seamless coordination with radiology, neuroradiology, and rehabilitation teams

Advice for Patients

If you have symptoms of visual disturbance, unexplained vision loss, or suspicion of a nerve/brain disorder, discuss with your neurologist whether a VEP test would offer useful information. At SSMC we will provide detailed explanation and guide you through the process.
