  • Title: The value of the examination of visuooculomotor reflexes in diagnosis of posterior cranial fossa lesions.
    Author: Kaźmierczak H, Pawlak-Osińska K.
    Journal: Int Tinnitus J; 2006; 12(1):61-3. PubMed ID: 17147042.
    Abstract:
    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, and accuracy. The patients suffered from posterior cranial fossa lesions, supratentorial damage, and peripheral vestibular disorders. We discovered that testing of smooth pursuit and saccades was very helpful in pointing to the localization of the damage in the posterior fossa. The frequency of the pathological saccadic and eye-tracking movements was similar for the different sites of deficit inside the posterior fossa, so recognizing the precise localization of lesion in this anatomical region was difficult.
