Sinusoidal smooth pursuit eye tracking at different stimulus frequencies: position error and velocity error before catch-up saccades in schizophrenia and in major depressive disorder.

30 Aug 2009 OBJECTIVE: The aim of the present study was to ascertain the extent of impairment of position error and velocity error processing in eye tracking dysfunction in schizophrenic and depressive patients. METHOD: A total of 21 schizophrenic and 19 ... Read more...

Rehabilitation approaches to hemineglect.

29 Jun 2009 BACKGROUND: Hemineglect is a difficult neurologic condition to rehabilitate. It arises predominantly from right brain injury, and manifests heterogeneously in clinical deficits such as poor visual exploration to the left, inaccurate assessment of ... Read more...

Superior oblique myectomy and trochlear resection for superior oblique myokymia.

29 Jun 2009 PURPOSE: To describe our experience with myectomy of the superior oblique muscle combined with resection of the trochlea for recurrent or primary superior oblique myokymia (SOM). DESIGN: Retrospective, interventional case series. METHODS: We ... Read more...

Technical information about 'Ocular Motility Disorders'

Definition: Disorders that feature impairment of eye movements as a primary manifestation of disease. These conditions may be divided into infranuclear, nuclear, and supranuclear disorders. Diseases of the eye muscles or oculomotor cranial nerves (III, IV, and VI) are considered infranuclear. Nuclear disorders are caused by disease of the oculomotor, trochlear, or abducens nuclei in the BRAIN STEM. Supranuclear disorders are produced by dysfunction of higher order sensory and motor systems that control eye movements, including neural networks in the CEREBRAL CORTEX; BASAL GANGLIA; CEREBELLUM; and BRAIN STEM. Ocular torticollis refers to a head tilt that is caused by an ocular misalignment. Opsoclonus refers to rapid, conjugate oscillations of the eyes in multiple directions, which may occur as a parainfectious or paraneoplastic condition (e.g., OPSOCLONUS-MYOCLONUS SYNDROME). (Adams et al., Principles of Neurology, 6th ed, p240)
