Usher's syndrome.

Usher’s syndrome is an autossomal recessive disease characterized by pigmentary retinopathy (PR) and bilateral sensorineural hypoacusis. Von Graefe and Liebreich were the first to publish a paper describing the association between PR and deafness. The incidence is 3 to 4.4 per 100,000 people. The prevalence is 3% to 6% among auditory impaired people.4 It may be subdivided into four types of which the type II is the mildest form. Patients present with slowly progressive moderate bilateral sensorineural dysacusis that predominantly affects high frequencies; there is preservation of vestibular function. PR begins in adolescents or in young adults.1 The aim of this study was to describe and analyze the clinical presentation of Usher’s syndrome and to compare these findings with the current literature. We described a clinical case of a 33-year-old patient that presented with the type II of Usher’s syndrome. The patient signed a free informed consent form before participating in the study, according to the Resolution 196/96 CNS/MS.
