Abstract:

Abstract Objective To identify and describe peripheral and central audiological abnormalities of patients with Vogt - Koyanagi - Harada syndrome . Materials and methods Prospective , cross - sectional , observational , descriptive study . Vogt - Koyanagi - Harada patients referred from an ophthalmologic centre were assessed for signs and symptoms of auditory pathology . Peripheral audiological and central auditory processing tests were performed . To standardize the latter , methodological controls were matched for sex , age and audiometric chart . Results Twenty - one patients were included ( 3 male , 18 female ) ; mean age , 40 .7 ( 11 .82 ) years . Nine of the 21 complained of tinnitus and 9 suspected hearing loss . Exclusively or mainly sensorial abnormalities on the pure tone audiometry chart were documented in 61 .9% ( mainly selective troughs at 4 and 8 kHz ) ; 95 .3% of patients had deficit in high - frequency audiometry . Five of the patients had sensorial disorders in the speech audiometry . No central auditory processing disorder was seen . Conclusions Most of the patients with Vogt - Koyanagi - Harada syndrome had objective peripheral audiological abnormalities , although few revealed any symptoms .
