Abstract
Başın belirli pozisyonlarında ortaya çıkan patolojik nistagmus anlatan pozisyonel nistagmus deyimi 3 ayrı nistagmo jenik faktöre bağlı 3 ayrı tip nistagmus içerir. Bunlar kinetik faktöre bağlı ve semisirküler kanal orijinli pozisyonlandırma nistagmusu; servikal faktöre bağlı ve proprioseptif veya vasküler orijinli servikal torsiyon nistagmusu; ve uzaysal faktöre bağlı ve otolit organ orijinli hakiki pozisyon nistagmusu 'dur. Görülmeleri vestibüler sisteminin bir kısmında veya tamamında kesin bir patolojinin bulgusudur. özellikle santral tipte pozisyon nistagmusu görülen olguların % 40'ında K.İ.Y.E.P. ortaya konabilmektedir.
The term positional nystagmus defines the pathological nystagmus appearing in certain positions of head and includes three different types of nystagmus caused by three different nystagmogenic factors. These are, the positioning nystagmus involving kinetic factors and originating from the semicircular canals; the neck-torsion nystagmus involving cervical factors and of proprioceptive and vascular origin and the true position nystagmus involving space fact or and originating from the otoli/h apparatus. The presence of positional nystagmus is the sign of disturbance in a part or in the whole of the vestibular system. The position of nystagmus of central type, especially , is of clinical diagnostic significance, as a space occupying intracranial lesion can be demonstrated in 40 % of these patients. The positional nystagmus is one of the surest, most objective, easily demonstrated and little time consuming o to neurological sign of disturbance in the vestibular system, without need to any technical equipment.
