The authors reported a 60 years old man who had reccurent attacks of bilateral sensori-neural hearing loss concurrent with impaired visual acuities and narrowing of visual fields. The attacks occured four times during two years. The severity of the attack became reduced following to each one. Observing the clinical course, auditory and ophthalmologic findings in this patient, it is reasonable to assume that cochlear and retrobulbar neuritis due to a viral infection had subsided gradually showing the repeated remission for two years, and the neuritis caused the coexistent auditory and visual disturbances.
