Phenotype Correlates Genotype of Inherited Retina Dystrophies

Patients with retina dystrophies (retinitis pigmentosa, cone>rods dystrophies, Usher and syndromic) will be correlated with genotype and validate inheritance mode by segregation analysis.

Patients with retina dystrophies (retinitis pigmentosa, cone>rods dystrophies, Usher and syndromic, etc.) will be correlated with genotype and validate inheritance mode by segregation analysis. Ocular exam of proband, parents and two unaffected siblings is needed, retina analysis, autofluorescence and ocular coherence tomography (OCT) are needed as well as family map. Blood samples 10ml max blood extraction will be sent and genotype will be analyzed.

Inclusion Criteria:

1. Diagnosis of inherited retina dystrophy or retinitis pigmentosa
2. Must be able to perform all study tests.
3. Must be able to visit every year.

Exclusion Criteria:

1) Not willing to visit every year.
