Visual evoked potentials (VEPs) induced by brief flashes and electroretinograms (ERGs) were recorded in 15 infants (9 prematures and 6 babies with perinatal cerebral injuries) suffering from important disturbances in their visual behavior (abnormal fixation, cortical blindness). The parallel evolution of the visual symptoms and the electrophysiological signs were studied and a good correlation was observed between these clinical and electrical signs. The authors insist on the clinical and prognostic value of the VEP in this category of infants.

Electrophysiological correlates of binocular stereo depth without binocular disparities.

A small region of background presented to only one eye in an otherwise binocular display may, under certain conditions, be resolved in the visual system by interpreting the region as a small gap between two similar objects placed at different depths, with the gap hidden in one eye by parallax. This has been called monocular gap stereopsis. We investigated the electrophysiological correlate of this type of stereopsis by means of sum potential recordings in 12 observers, comparing VEP's for this stimulus ("Gillam Stereo", Author BG has strong reservations about this term) with those for similar stimuli containing disparity based depth and with no depth (flat).

Purpose: To determine the refractive state of tree shrew eyes using visual evoked potentials (VEP's) recorded from primary visual cortex and compare the values with those obtained with streak retinoscopy and with an autorefractor.
Methods: VEP's were recorded in seven normal tree shrews and three animals in which approximately 5 D of myopia (relative to control eye) was induced by monocular -5 D lens wear. While the animals were awake, refractive correction was measured with an autorefractor before and after cycloplegia (1% atropine and 2.
