Nystagmus | PDF | Vestibular System | Light

Nystagmus | PDF | Vestibular System | Light There are three forms of physiologically induced nystagmus; vestibular, optokinetic and end point nystagmus. vestibular nystagmus occurs during self rotation even in darkness. This type of nystagmus can be associated with a problem with the eyes themselves or with a problem with the parts of the brain which control eye movements. but sometimes children develop nystagmus without any of these problems. the way the brain and eyes work together is known as the visual system. Nystagmus is an important tell tale sign in the evaluation of vestibular function. nystagmus is defined as a rhythmical, involuntary, oscillatory movement of the eyes without a cognitive, visual or vestibular stimulus. A fundamental characteristic of peripheral vestibular nystagmus, in particular horizontal nystagmus, is that it is suppressed by visual fixation. this means that a patient with a vertigo attack of peripheral vestibular origin might have no obvious spontaneous nystagmus on clinical examination.

Take your finger out past 18 24” to examine if the patient has full ocular range of motion. ask the patient to follow moving target that is held several feet in front of the patient’s face (to avoid convergence of eyes.) hold the patient’s head stationary. The pathophysiology of spontaneous upbeat (ubn) and downbeat (dbn) nystagmus is reviewed in the light of several instructive clinical findings and experimental data. The subcommittee for vestibular signs and exam ination techniques is charged with developing consensus definitions for vestibular signs and exam ination techniques used frequently in the assessment of patients with vestibular symptoms.
