Abstract:
Ushers syndrome is an autosomal recessively inherited trait that characterized by progressive retinitis pigmentosa combining night blindness with a congenital, nonprogressive sensorineural hearing impairment of variable severity. Speech disorder, vestibular ataxia, mental deficiency, psychosis, and cataract are usually present. We experienced a case of type IV Ushers syndrome in 28 year-old woman that showed the night blindness with decreased visual acuity that had been developed 7-8 years before and congenital sensorineural hearing loss. In fundoscopic examination, characteristic bone corpuscle pigmentation in the periphery, and narrow arteries are found. Her electroretinogram and pure tone audiometric findings show non recordable wave forms and bilateral sensorineural hearing loss. She has mild mental retardation also.
