Abstract
Objective

To identify and describe vestibular abnormalities in patients with Vogt-Koyanagi- Harada syndrome (VKH).

Materials and method

Prospective, cross-sectional, observational, and descriptive study. Patients with VKH referred by an ophthalmological centre were interrogated and physically examined in search of signs of vestibular abnormalities, and if positive, they underwent videonystagmography, computerized dynamic posturography, tonal audiometry, and tympanometry.

Results

Out of 21 patients with VKH, only 10 were included in the study due to presenting data of vestibular abnormalities (10/10 with vestibular symptoms and 9/10 with abnormalities in the physical examination). The mean age was 37.8 years. The videonystagmography was mainly abnormal in ocular saccades test (10/10). The posturography showed a higher alteration of the visual (4/10) and vestibular (4/10) afferents. A diagnosis of benign paroxysmal positional vertigo was mostly concluded (6/10). None presented abnormalities of the middle ear nor data of central pathology, 6/10 presented abnormalities in tonal audiometry.

Conclusions

Peripheral vestibular disorder is often present in the population with VKH.

Resumen
Objetivo

Identificar y describir alteraciones vestibulares en pacientes con síndrome de Vogt- Koyanagi-Harada (VKH).

Material y método

Estudio prospectivo, transversal, observacional y descriptivo. Se interrogó y exploró físicamente a pacientes con VKH referidos de un centro oftalmológico, en busca de datos de alteración vestibular. De ser positiva, se les realizó videonistagmografía, posturografía dinámica computarizada, audiometría tonal y timpanometría.

Resultados

De 21 pacientes con VKH, sólo se incluyeron a 10 por presentar datos de alteración vestibular (10/10 con síntomas vestibulares, 9/10 con alteraciones en la exploración física). Media de edad, 37,8 años. Videonistagmografía principalmente alterada en prueba de sacadas oculares (10/10). Posturografía con mayor alteración de las aferencias visual (4/10) y vestibular (4/10). Se concluyó mayoritariamente el diagnóstico de vértigo postural paroxístico benigno (6/10). Ninguno presentó alteración del oído medio ni datos de afección central; 6/10 tuvieron alteraciones en la audiometría tonal.

Conclusiones

La población con VKH frecuentemente sufre afección vestibular periférica.
