Evaluation of Oculomotor Tests Findings Using Videonystagmography in Young Adults

Öz

Purpose: Videonystagmography is one of the important laboratory test which evaluates vestibular system. VNG consists of several subtests such as oculomotor tests, gaze stabilization tests, positional tests and caloric test. Oculomotor tests (saccade, tracking and optokinetic tests) assess central vestibular system. The aim of this study was to examine the results of oculomotor test in young adults by using VNG. 

Material and Method: In this paper, the results of oculomotor tests were evaluated in 25 young adults (12 males and 13 females) between 18-25 years of age with normal hearing and without vestibular problems.

Results:The present study, a data base of normal values for VNG oculomotor tests in healthy young adults. 

Conclusions: Establishing normative data can provide references ranges using by clinicians to interpret results of videonistagmografic oculomotor tests.

Genç Erişkinlerde Videonistagmografi ile Yapılan Okülomotor Test Sonuçlarının İncelenmesi

Öz

Amaç: Videonistagmografi (VNG), vestibüler sistemi değerlendiren önemli bir laboratuvar testidir. VNG; okülomotor testler, gaze stabilizasyon testleri, pozisyonel testler ve kalorik alt testlerinden oluşur. Okülomotor testler (sakkad, pursuit ve optokinetik testler), santral vestibüler sistemi değerlendirir. Bu çalışma, genç erişkin bireylerin videonistagmografi (VNG) cihazı ile yapılan okülomotor test sonuçlarını incelemek amacıyla yapılmıştır. Gereç ve Yöntem: Bu makalede, 18-35 yaş aralığında, normal sınırlarda işitme eşiklerine sahip, vestibüler problemi olmayan, 25 genç erişkin bireyin (12 erkek 13 kadın) okülomotor değerlendirme sonuçları analiz edilmiştir. Sonuçlar: Çalışmada, VNG okülomotor testlerinin sağlıklı genç erişkinlere ait normatif değerleri sunulmuştur. Tartışma: Klinisyenlerin videonistagmografik okülomotor testlerin sonuçlarını yorumlamada kullanabilecekleri referans değerler belirlenmiştir.
