A patient with chronic inflammatory demyelinating polyneuropathy (CIDP) presented with an isolated unilateral adduction deficit and ptosis. Investigations were negative until the onset of limb weakness and fatigue 2 years later. At that time, electroneuromyography, cerebrospinal fluid examination, and magnetic resonance imaging confirmed the diagnosis of(More)
Transient flash VEPs allow objective assessment of visual function and are easily recorded in young infants. However, due to their high variability, they are an insensitive surrogate marker of visual development. The aim of our study was to investigate the early maturation of temporal characteristics of steady-state flicker VEPs. Data from 53 VEP sessions(More)
A relative afferent pupillary defect (RAPD) is usually a sign of visual dysfunction. Here, an unusual case of an RAPD combined with vertical strabismus but normal vision is described. Implications for pupillary pathway anatomy are discussed. A 12-year-old girl with chronic headache was shown to have a midbrain tumour. She presented to us with intermittent(More)
S ynergistic divergence is a well-established clinical condition in which abduction arises on attempted adduction, leading to simultaneous abduction of both eyes on lateral gaze. Synergistic divergence can occur as an extreme form of Duane syndrome, where most if not all oculomotor nerve branch fibers originally directed to the medial rectus muscle(More)
