Visual Electrodiagnostic Service
For patients requiring an objective assessment of visual integrity, we offer special techniques for investigating the vision-induced electrical signals from the retina and the visual cortex of the brain. These tests provide valuable diagnostic information about the functioning of anatomical structures involved the early stages of vision. A referral is normally required.
