Measurement of interocular delays with dynamic random-dot stereograms.
A psychophysical method of measuring interocular delay based on dynamic random-dot stereograms is presented. The measurement requires only about 2 min. The sensitivity of this method to detect differences in the transmission times of the two optic nerves is demonstrated in patients with multiple sclerosis and in healthy subjects in whom interocular delays were produced by using different luminance levels for each eye. This new method may be a useful and economic method for monitoring the time course of optic neuritis.
