Evoked occipital potentials have been recorded from scalp electrodes in response to focal visual illumination. To accomplish this, a computer specifically designed for this purpose and capableof integrating any area under an evoked waveform and summing these areas to reveal a response has been used. A decoder is available luhich can signed ivhen any preset digital value is reached or exceeded. Illumination of the optic papilla has been employed with different stimulus intensities and areas under conditions of light adaptation to demonstrate that focal retinal illumination can be achieved. Some patients with visual field, defects have been studied in an attempt to demonstrate the possibility of objective visual field testing.
