摘要
Importance: Sympathetic ophthalmia (SO), a rare bilateral panuveitis following penetrating ocular trauma or ocular surgery to one eye, shares a strikingly similar ocular pathology to that of Vogt Koyanagi Harada disease (VKH). Audiovestibular dysfunction is a major extraocular manifestation of VKH; however, to date, only a few cases of sympathetic ophthalmia associated with hearing loss have been reported from ophthalmologists, but not otolaryngologists. Accordingly, little is known about the audiovestibular findings in patients with SO. We herein present two cases of SO with preceding bilateral hearing loss. Observations: The patient in Case 1, an 80-year-old female, experienced acute bilateral hearing loss. Five days after the onset of hearing loss, she presented with sudden bilateral blurred vision. In Case 2, a 32-year-old female noticed acute bilateral hearing loss and also experienced acute bilateral blurred vision the subsequent day. Patient 1 had a history of a penetrating injury to the right eye 25 days before the onset of hearing loss, while patient 2 had previously undergone right vitreous surgery twice for the treatment of a myopic macular hole and retinal detachment 36 and 43 days prior to the current symptom onset. Both cases were diagnosed as SO based on ocular findings of bilateral panuveitis and the history of ocular insult. Patient 1 carried HLA-DR4, HLA-DR15, HLA-A33, HLA-A24, HLA-B44 and HLA-B52, and patient 2 carried HLA-DR4. Audiograms showed bilateral mild to moderate sensorineural hearing loss in both cases, with normal auditory brainstem responses and deteriorated distortion product otoacoustic emission amplitudes. In addition, the significant recruitment phenomenon observed in case 1 suggested a cochlear origin of the hearing loss. Both patients received corticosteroid therapy, and the cochlear signs and symptoms recovered within one month. Conclusions and relevance: This is the first report to describe the comprehensive audiovestibular findings in patients with SO. In the present study, acute bilateral hearing loss developed a couple of days prior to the onset of bilateral visual loss and auditory examinations suggested a cochlear etiology in both cases.
