Fusional response to extrafoveal stimulation.
Horizontal and vertical fusional responses to extrafoveal stimulation were examined. An objective binocular eye movement measuring technique was utilized to position an artificial, stabilized scotoma over the central 10 degrees diameter area of one eye. The responses contained both a motor and nonmotor, or sensory, component. The monocular eye movements were asymmetrical.
