Visual perception is one of the most complex functions of the human brain. Every moment, millions of electrical signals travel from the eyes through the optic nerves to different regions of the brain, enabling us to recognise faces, read text, detect motion, and understand our environment. When this electrical “highway” experiences a disruption—due to disease, inflammation, compression, or injury—the effects can be profound. Visual Evoked Potential (VEP) is one of the most reliable and non-invasive tests used to measure the functional integrity of the visual pathway. Unlike imaging modalities such as CT or MRI that show structural abnormalities, VEP evaluates...
