Actual (reported)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).
