Electro-oculography in infants.

To record the electro-oculogram in infants without using general anesthesia and passive globe rotation, we used the static vestibular reflex in which compensatory eye movements occur in response to angular rotation of the semicircular canal. To produce these eye movements, we placed the infant in a supine position in his mother's arms in a rocking chair and, while he nursed from a bottle, directed his attention to a distracting stimulus. We recorded the electro-oculogram during rocking under conditions of light and dark adaptation. We used the electro-oculograms to calculate the conventional light-to-dark amplitude ratio.
