Dominant optic nerve atrophy with progressive hearing loss and chronic progressive external ophthalmoplegia (CPEO).

This paper describes a family where chronic progressive external ophthalmoplegia is associated with dominant optic atrophy and progressive sensorineural deafness. This may be a possible association in the same family of two diseases: progressive external ophthalmoplegia and dominant optic atrophy with progressive hearing loss. However, we believe that this family represents an unusual manifestation of ophthalmoplegia plus.
