Clinical visual electrophysiological testing is not currently used outside the hospital eye service. However, newer techniques are being developed which make the test more accessible and adaptable to the optometrist, without the need for multiple electrodes and complicated visual stimuli targets. Electrophysiology, measuring the electrical activity in the visual pathway, makes it possible to assess the functioning of different elements of the pathway and provides unique information leading to definitive diagnosis of ocular disease. Dorothy Thompson is Director of Education of the International Society for Clinical Electrophysiology of Vision. She works as a consultant clinical scientist in visual electrophysiology in the Ophthalmology Department at Great Ormond Street Hospital. In this piece, Dorothy discusses her work with Simranjit Gill.
