Binocular disparity in visual evoked responses. Clinical evidence in normal and stereoblind subjects. 1985

G Nuzzi, and A Franchi

The authors have utilized a binocular flat or stereoscopic pattern (grating) to record visual evoked responses (VER) in normal and strabismic subjects. The aim was to find an electrophysiological correlate with the degree of binocular interaction in these subjects. The perception of the grating as tridimensional or flat derived from the disparity obtained with Polaroid filters placed in front of the eyes. In normal subjects, the results demonstrated a significant increase of VER amplitude during tridimensional perception of the pattern. In strabismic subjects the electrophysiological response was not correlated with the binocular conditions.

D013285 Strabismus Misalignment of the visual axes of the eyes. In comitant strabismus the degree of ocular misalignment does not vary with the direction of gaze. In noncomitant strabismus the degree of misalignment varies depending on direction of gaze or which eye is fixating on the target.
