The value of the examination of visuooculomotor reflexes in diagnosis of posterior cranial fossa lesions.
The aim of this study was to compare the frequency of pathological types of smooth-pursuit and saccadic movements in different localizations of vestibular lesions. We tested 112 patients using videonystagmography. The smooth pursuit was appreciated qualitatively on the basis of Malecki's patterns. We analyzed the saccadic movements taking three parameters into consideration: latency, velocity, ...
متن کاملRadioisotope scanning in posterior fossa lesions.
It has been alleged that radioisotope scanning of posterior fossa lesions is of little value (1-8) or at best, difficult (9,10) and frequently unrewarding (11). Some clinics even report the virtual abandonment of posterior fossa scanning (12,13). On the other hand, there are those who maintain that scanning of the posterior fossa is a worthwhile adjunct in the evaluation of lesions in that re g...
متن کاملObservations on blink reflexes.
A reflex wink, which resulted from a tap over the supraorbital region of the face, was described by Overend (1896). He observed that the reflex was the product of facial stimulation, for it was present in the blind. In the 25 years following this discovery it was realized that reflex winking (unilateral contraction of the homolateral orbicularis oculi) or blinking (bilateral contraction) could ...
متن کاملStatus epilepticus associated with subtentorial posterior fossa lesions.
BACKGROUND Nonconvulsive status epilepticus (SE) is a frequent complication in critically ill patients in the intensive care unit. While seizures have been reported in association with subtentorial posterior fossa lesions, the frequency of occurrence of SE among these patients is not known. OBJECTIVES To examine prevalence, clinical features, potential risk factors, and outcome of SE among pa...
متن کاملBlink reflexes in severe traumatic coma.
Blink reflexes were studied in 21 patients in coma after severe head injury. Our observations suggest that blink reflexes are a simple, objective, neurophysiological test to evaluate brainstem function. Correlations between these reflexes and the anatomoclinical stanges of coma and the Glasgow coma scale have been established. Presence of the early R1 component shows the integrity of at least a...
