What are Visual Evoked Potentials (VEPs)?
These are tests of the pathway between the eye and the back of the brain. You will be asked to look at the centre of a television screen that has a moving black and white chequer board pattern. Each eye is tested separately, with a patch covering the eye not being investigated. This is a painless procedure and there are no after effects. When finished you will be able to return home or to work/school.
