These patients generated fewer square‐wave jerks than did nonpsychiatric subjects for 10% left‐moving targets. These results suggest an abnormality of smooth‐pursuit initiation among patients with schizophrenia. These abnormalities include signs of dysfunction of ocular alignment (skew deviation, ocular tilt reaction, and environmental tilt), various types of nystagmus, smooth pursuit [ncbi.nlm.nih.gov] RESULTS: Gait ataxia (88%), vertigo /dizziness (91%), nausea/vomiting (73%), dysphagia (61%), hoarseness (55%), Horner sign (73%), and facial (85%) and hemibody (94%) sensory [ncbi.nlm.nih.gov] Test smooth pursuit by having the patient follow an object moved across their full range of horizontal and vertical eye movements. Also, observe the eyes at rest to see if there are any abnormalities such as spontaneous nystagmus (see below)or dysconjugate gaze (eyes not both fixated on the same point) resulting in diplopia (double vision). 32. BackgroundMultiple sclerosis (MS) is a diffuse disease that disrupts wide-ranging cerebral networks.

Saccadic breakdown of smooth pursuit is also common with cerebellar involvement , though a very non-specific finding. Although the scope of this article focuses on saccades and does not encompass a comprehensive review of nystagmus and abnormalities of other types of eye movements, it is important to note the presence or absence of gaze-evoked or downbeat nystagmus (DBN), which may only be seen when the patient is placed in a supine position (eg. positioning DBN), in a patient with parkinsonism. smooth pursuit motion is very fast Central Diplopia Patient report.

Smooth pursuit abnormalities

Smooth pursuit (SP) maintains visual acuity of slow-moving objects by keeping their image near the fovea. SP impairment is recognized by saccadic pursuit and occurs toward the side of lesions at the parietal, occipital, and temporal lobe junction (area V5); the frontal eye field and their projections to the basal pontine nuclei; paraflocculus; and caudal cerebellar vermis.

These ideas have been volving sensibility, a certain pursuit or a particular interest; style not just as appearance, but as an to display a perfectly smooth, even, and soft complexion.

The clinical assessment of oculomotor function can help to differentiate diagnosis, while electrophysiological measures provide useful biomarkers for the understanding of disease physiopathology and progression. The results show that both smooth pursuit and saccadic abnormalities are present at the onset of schizophrenia and are integral to the disorder.

Many methods for quantitative analysis of SPEM have been designed, though most are still uncommon in present clinical use.
