Brief Summary in Lay Language

This study aims to characterize Usher patients in order to correlate this data with genetic
information.

Tasks:

- Standardization and improvement of Usher syndrome diagnosis: refine and elaborate
special tests of visual and otological function in association with genotype that
enable to determine the most significant markers for Usher disease progression and
therapeutic effect.

- Perform genotype and phenotype correlations in Usher syndrome patients

- Develop and maintain database for phenotypically and genotypically well-characterized
patient cohorts, suitable for future therapeutic trials

Primary Outcome

- Genotype and phenotype correlations in Usher syndrome patients; time frame: up to 3 years (2016); Protocol outline: patients undergo clinical and molecular studies. These include extensive ophthalmologic (best corrected visual acuity, refraction, tonometry, color vision, visual field testing, pupillography*, full-field electroretinogram, multifocal electroretinogram, autofluorescence imaging, optical coherence tomography, adaptive optics*) examination, audiologic and vestibular evaluation and obtaining blood samples for genetic analysis.
