Progressive visual loss, diabetes mellitus, and associated abnormalities (DIDMOAD syndrome).
A syndrome including juvenile-onset diabetes mellitus, optic atrophy, diabetes insipidus, and high-frequency sensorineural hearing loss, expressed completely or partially, is being identified with greater frequency. Visual loss may be progressive and accompanied by primary optic atrophy. Concurrent diabetic retinopathy has only rarely been reported. Visual acuity may deteriorate to less than 20/400. The etiology is unknown. However, histopathologic studies indicate that the diabetes insipidus, optic atrophy, and neurosensory hearing loss represent progressive degenerative conditions. Inheritance appears to be autosomal recessive with incomplete penetrance. The syndrome is rare; therefore, a complete neuroophthalmologic and neuroradiologic evaluation is imperative to rule out a mass lesion. This syndrome should be considered in young people with visual loss and optic atrophy of unknown etiology even if they are not known juvenile diabetics.
