Acquired Periodic Alternating Nystagmus
대한신경과학회지 22권 5호 548 Periodic alternating nystagmus (PAN) is a rare type of spontaneous horizontal nystagmus, characterized by periodical reverse of direction with a transition period in between. PAN can occur in both congenital and acquired forms. We report a patient with acquired PAN associated with meningoencephalitis. To our knowledge, only a case of congenital PAN has been previously report...
متن کاملLatent nystagmus and acquired pendular nystagmus masquerading as spasmus nutans.
SUMMARY We used ocular motility recordings to identify the characteristics of a rare combination of conjugate, horizontal jerk, and pendular nystagmus in a 9-year-old boy. The clinical diagnoses were amblyopia, left esotropia, congenital nystagmus, and an apparently uniocular pendular nystagmus that mimicked spasmus nutans. Ocular motility recordings revealed an unusual latent/manifest latent n...
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...
متن کاملIs acquired pendular nystagmus always phase locked?
A patient with multiple sclerosis presented with oscillopsia due to an acquired pendular nystagmus that was dissociated in amplitude, being larger in the eye with a relative afferent pupil defect. Eye movement recordings showed an unusual dissociation in nystagmus frequency as well. Although the frequencies differed, the eyes remained phase locked as the right eye was oscillating exactly twice ...
متن کاملMagnetic Oculomotor Prosthetics for Acquired Nystagmus
PURPOSE Acquired nystagmus, a highly symptomatic consequence of damage to the substrates of oculomotor control, often is resistant to pharmacotherapy. Although heterogeneous in its neural cause, its expression is unified at the effector-the eye muscles themselves-where physical damping of the oscillation offers an alternative approach. Because direct surgical fixation would immobilize the globe...
