This study will carry out a detailed descriptive analysis of a large population of patients with hereditary retinal dystrophies (HRD): clinical, paraclinical and genetic data.
The information drawn from these analyzes will provide a better understanding of the pathophysiology of these rare diseases and this may ultimately impact the medical management of patients (targeted therapy).

|Patients with suspicion of hereditary retinal dystrophy||
Optical coherence tomography angiography (OCT-A)
Procedure: Visual acuity (ETDRS)
Visual acuity tested with ETDRS score (Early Treatment Diabetic Retinopathy Study)
- Description of the phenotypic characteristics of patients with hereditary retinal dystrophies. [ Time Frame: Baseline ]Phenotypic diagnosis of the type of retinal dystrophy based on all the examinations performed as part of the usual care and examinations added by the research (OCT-Angiography - Optical coherence tomography, and visual acuity with ETDRS scale : Early Treatment Diabetic Retinal Study, ETDRS).
- Description of the genotypic characteristics of patients with hereditary retinal dystrophies. [ Time Frame: Baseline ]Determination of the genetic mutations responsible for retinal dystrophy in order to confirm the phenotypic diagnosis and identify correlation between the phenotypic and genotypic characteristics
