[Usher syndrome]

Abstract

We present the case report of two brothers, PF-21 years old and PN-19 years old, to whom the fundus examination, perimetry and dark adaptation established the diagnosis of Retinitis Pigmentosa. The otorhinolaryngology exam and the audiogram revealed, in both cases, bilateral sensorineural deafness. The simultaneous presence of these two conditions completes the clinical findings of Usher syndrome. The common ectodermic origin of the retina and the inner ear could explain this pathological association.
