Neuro-ophthalmological abnormalities in HTLV-I associated myelopathy

Abstract
To determine whether neuro-ophthalmological abnormality exists in HTLV-I Associated Myelopathy (HAM), 22 patients were examined using electrooculography and visual evoked potentials and compared with controls. Eleven cases had mild abnormalities in smooth pursuit movements. Of these 11 patients, four had transient diplopia or jerky eye movements. One patient had a delayed P100 latency in the visual evoked potentials. These data suggest that the central nervous system may also be involved in HAM.
