[Vestibular and oculomotor disorders in patients with congenital strabismus].
A group of patients with congenital endotropia or exotropia was investigated in their capacity to perform reflex eye movements. Some patients had a successful surgical correction of their eye defect. The functions measured were the vestibulo-oculomotor reflex, the feedback control loop for searching and following eye movements and the optomotor reflex. A loss in the functional capacity was displayed in all the tests done. The average value of the losses found for the whole group, according to the test used, were from 8 to 27% for the vestibulo-oculomotor reflex; 22 to 42% for the eye tracking feedback loop, and 48% for the optomotor reflex. The deficit was not due to the incorrect eye position, because the successfully operated subjects had the same magnitude of the motor defect than the non-operated patients.
