Abstract

Eleven children with infantile autism or autistic-like conditions were examined with oculomotor tests and with auditory brainstem response audiometry. Measurements of voluntary, horizontal non-predictable saccades showed that the eye motor function was abnormal in six (55 per cent) of the eleven patients. The saccades were hypometric in all six instances and the saccadic velocity was reduced in four instances. The abnormalities observed are consistent with brain dysfunction, in most cases probably indicating ponto-cerebellar involvement. In five instances ABR was found to be abnormal which indicates brainstem dysfunction. Oculomotor dysfunction and/or ABR abnormality was observed in eight (73 per cent) of the patients studied.
