[Electrooculographic findings in patients with neurofibromatosis]

Neurofibromatosis are frequent genetic syndromes, with the electrooculographic examination (EOG) as an useful tool in their evaluation. We present the EOG findings of 16 patients with this entity which were seen at our Department between 1969 and 1991. Mean of age was 31 years. Nine patients were female (56%). The most frequent pathologic findings were: spontaneous nystagmus (37.5%) and abnormalities in the pursuit tracking test (31.2%). These results are discussed and the main literature concerning this matter is reviewed.
