Nystagmus slow and fast phase
Web24 de dic. de 2024 · Nystagmus is defined by rhythmic, abnormal eye movements with a “slow” eye movement driving the eye off the target followed by a second movement … WebThe fast phase of the nystagmus is the correction of the slow phase by our higher-level cortical function. It is also the phase for which the nystagmus is named. For example, a lesion in the left vestibular system will cause a slow drifting of the eyes toward the left, with a corrective right-beating fast phase. Such that, a left lesion is said ...

WebSummary of key points: Nystagmus is an involuntary, rapid, rhythmic, oscillatory eye movement with at least 1 slow phase. Jerk nystagmus has a slow phase and a fast phase. Pendular nystagmus has only slow phases. Nystagmus is distinguished from other types of oscillatory eye movements, such as saccadic intrusions or oscillations. WebIn a normal patient, cool water decreases the temperature of the endolymph and inhibits the hair cell activity on that side. This produces nystagmus of the eyes with the slow phase (S) towards the side of irrigation and the fast phase (F) away from the irrigation. With warm water irrigation, the opposite happens.
WebFoveating fast phases were generated during lower slow-phase velocities whereas, defoveating fast phases occurred during higher slow-phase velocities. The bidirectional model simulated Alexander's law behavior under all viewing and fixation conditions. Our ocular-motor model accurately simulates LMLN-patient ocular motility data and provides …
