Abstract

An electro-oculographic study has been performed in 11 patients affected by hereditary degenerative ataxias (5 Friedreich's ataxias, 4 olivopontocerebellar atrophies and 2 late onset cerebellar ataxias). Electrooculographic records were obtained during saccades, pursuit movements and fixed gaze. Saccadic latency, saccadic speed and morphologic features were studied. In Friedreich's ataxia ocular motility was less accurate than in olivopontocerebellar atrophy and in late onset cerebellar ataxia.

摘要

对11例遗传性退行性共济失调患者（5例弗里德赖希共济失调、4例橄榄脑桥小脑萎缩和2例迟发性小脑共济失调）进行了眼电图研究。在扫视、跟踪运动和固定注视期间记录眼电图。研究了扫视潜伏期、扫视速度和形态学特征。在弗里德赖希共济失调中，眼球运动比橄榄脑桥小脑萎缩和迟发性小脑共济失调更不准确。
