EYE-MOVEMENT AND ELECTROPHYSIOLOGICAL FINDINGS IN AN INFANT WITH HEMISPHERIC PATHOLOGY

A visually unresponsive infant had a normal ophthalmological examinati on. Eye-movement studies using electro-oculography revealed asymmetric al binocular smooth pursuit, binocular optokinetic nystagmus and vesti bulo-ocular reflex. Electrophysiological testing showed markedly asymm etrical occipital flash and pattern visual evoked potentials. Both inv estigations suggested a posterior right-hemispheric problem, which was confirmed with cranial ultrasound. This case study illustrates the us efulness of non-invasive techniques in neuro-ophthalmological investig ations of young children.
