This is an eye test to measure the electrical activity in the retina.
Examination of the electrical activity of the retina (light-sensitive layer of cells at the back of the eye), for the purpose of disease diagnosis.
A test used to evaluate the electrical function of the eye. It records the electrical changes in the retina of the eye after stimulation by light. It is similar in function to an EKG, which measures the electrical activity in the heart.
Electrical waves reflecting summed activity from the retina evoked by a light flash. Has characteristic deflections recorded from side of head close to eye socket.
