Quick phases of infantile nystagmus show the saccadic inhibition effect.
PURPOSE Infantile nystagmus (IN) is a pathological, involuntary oscillation of the eyes consisting of slow, drifting eye movements interspersed with rapid reorienting quick phases. The extent to which quick phases of IN are programmed similarly to saccadic eye movements remains unknown. We investigated whether IN quick phases exhibit 'saccadic inhibition,' a phenomenon typically related to norm...

15 صفحه اولComparison of the main sequence of reflexive saccades and the quick phases of optokinetic nystagmus.
BACKGROUND/AIMS Abnormalities in the saccadic main sequence are an important finding and may indicate pathology of the ocular motor periphery or central neurological disorders. In young or uncooperative patients it can be difficult eliciting a sufficient number of saccades to measure the main sequence. It is often assumed that the quick phases of optokinetic nystagmus (OKN) are identical to sac...
متن کاملSaccades and the quick phase of nystagmus.
Quick phases of vestibular nystagmus and saccades were compared on the basis ofthe shape of their time courses and their amplitude-duration relationships in the alert intactmonkey. Both rapid movements are almost identical when nystagmus is induced naturally byrotation. Visual field structure, illumination and darkness affect the speed of both types ofmovements similarly. This i...
