Supranuclear control of ocular motility.
Ocular motor behavior is dictated by visual demands. The entire brain is involved in programming and executing of eye movements. Gaze shifts performed under natural conditions require an elaborate supranuclear coordination between various motor and sensory mechanisms. Recently, a wealth of novel data emerging from animal studies along with functional imaging in humans expanded and modified trad...
متن کامل[Sinusitis and ocular motility disorders].
BACKGROUND Secondary inflammatory orbital involvement due to acute or chronic sinusitis is common. The pneumatized system of the paranasal sinuses is abut to the bones of the orbit in up to 80 percent, therefore the association is a seductive theory due to their anatomic closeness. Typically, sinusitis can influence ocular motility by affecting single muscles or a combination of muscles/cranial...
متن کاملInternuclear and supranuclear disorders of eye movements: clinical features and causes.
Eye movements bring visual stimuli to the fovea and also maintain foveal fixation on a moving target and during head movements. These movements are performed by the ocular motor system that consists of ocular motor nerves and nuclei in the brainstem originating in the cerebral cortex, cerebellum, vestibular structures, and the extraocular muscles. The ocular motor system is divided according to...
متن کاملNystagmus and Related Ocular Motility Disorders
General Concepts and Clinical Approach This chapter concerns abnormal eye movements that disrupt steady fixation and thereby degrade vision. We now know a good deal about the normal anatomy, physiology, and pharmacology of ocular motor control (1). Our approach is to apply this knowledge to nystagmus and other ocular oscillations, since pathophysiology provides a sounder conceptual framework th...
متن کاملAcquired Ocular Motility Disorders and Nystagmus
Eye movement disorders may be considered in two categories: those that cause incomplete eye movements (ophthalmoparesis) and those that cause excessive eye movements (saccadic intrusions and nystagmus). Central to an understanding and correct diagnosis of abnormal eye movements is the evaluation of ocular alignment, ocular motility, and each functional class of eye movements: optokinetic, vesti...
