LED perimeter for visual field analysis by mapping of small field evoked potentials.
A new type of visual field perimeter, equipped with conic light emitting diodes (LEDs) located at 10 degrees intervals automatically programmable is described. The device is meant for visual field analysis by mapping of the evoked responses derived from the retina and specific cortical projection areas.
