Periferik Vestibüler Fonksiyon Bozukluğu Olan Hastalarda Okülomotor Test Değişiklikleri

Amaç: Periferik vestibüler hipofonksiyon tek taraflı veya bilateral olarak görülebilir. Çalışmanın amacı tek taraflı ve bilateral periferik vestibüler zayıflığı olan hastalarda okülomotor test sonuçlarını araştırmaktır. Gereç ve Yöntemler: Çalışmaya, kalorik test sonucuna göre normal periferik vestibüler sistemi olan 35 hasta, idiopatik tek taraflı periferik vestibüler zayıflığı olan 35 hasta ve idiopatik bilateral periferik vestibüler zayıflığı olan 30 hasta dahil edildi. Tüm hastalara sakkad test, smooth pursuit test ve optokinetik testlerden oluşan okülomotor testler yapıldı ve değerlendirildi.Bulgular: Smooth pursuit testi açısından tek taraflı periferik vestibüler zayıflığı olan 35 hastanın %14,2 5’inde, bilateral periferik vestibüler zayıflığı olan 30 hastanın %30,0 9ʼunda patoloji gözlenirken, kontrol grubunda patoloji gözlenmedi.Sonuç: Smooth pursuit patolojisi hem tek taraflı periferik vestibüler zayıflığı olan hem de bilateral periferik vestibüler zayıflığı olan hastalarda görülebilir. Optokinetik test ve sakkad test tek taraflı veya bilateral periferik vestibüler zayıflıktan etkilenmez

Oculomotor Test Changes in Patients with Peripheral Vestibular Dysfunction

Objective: Peripheral vestibular hypofunction can be seen unilaterally or bilaterally. The aim of this study is to investigate the oculomotor test results in patients with unilateral and bilateral peripheral vestibular weakness.Material and Methods: The study consisted of 35 patients with a normal peripheral vestibular system, 35 patients with idiopathic unilateral peripheral vestibular weakness and 30 patients with idiopathic bilateral peripheral vestibular weakness according to the caloric test. Oculomotor tests including saccade, smooth pursuit and optokinetic tests were performed and evaluated in all patients.Results: A pathology was observed in 5 of 35 14.2% patients with unilateral vestibular weakness and 9 of 30 30.0% patients with bilateral vestibular weakness while no pathology was observed in the control group in terms of smooth pursuit. Conclusion: Smooth pursuit pathology can be seen both in patients with unilateral vestibular weakness and bilateral vestibular weakness. The optokinetic test and saccade test are not affected by unilateral vestibular weakness or bilateral vestibular weakness
