A Case of Labyrinthitis Occuring in Undiagnosed Congenital Nystagmus

“…11) In most cases, MRI is performed as the first test; however, structural abnormalities are rarely found. 12) Huang, et al 13) analyzed the presence of inner ear diseases in 50 patients with congenital nystagmus and confirmed that 17 patients had accompanying inner ear diseases, such as labyrinthine dysfunction, endolymphatic hydrops, sequelae of otitis media, and congenital hearing loss. Hence, interpreting nystagmus arising from labyrinthine disease can be challenging in patients with congenital nystagmus.…”

“…15) Such reversed OKN mainly appears in patients with congenital nystagmus and can be accompanied by cerebellar or brainstem abnormalities acquired later. 13) However, bidirectional reversed OKN appears only in congenital nystagmus. 15) There was no mention of abnormal eye tremors in the patient's initial medical history.…”
