Pulfrich stereo-illusion phenomenon in serous sensory retinal detachment of the macula

Four patients (three men, 68, 35, and 33 years old, and one woman, 46 years old) had central serous elevation of the macula with abnormal latency of the visual-evoked potential and spontaneous Pulfrich phenomenon. In three instances both the electrophysiologic test and the clinical Pulfrich test reverted to normal on resolution of the retinopathy. This correlated with normalization of visual-evoked potential latency in the affected eye.
