Multi-center Observation of the Natural Course of Inherited Retinal Dystrophies

Multi-center Observation of the Natural Course of Inherited Retinal Dystrophies

Based on a clinical multi-center study of the natural course of inherited retinal dystrophies in Chinese population, screening fundus imaging indicators for patients with Chinese inherited retinal dystrophies, describing the clinical features of Chinese patients with inherited retinal dystrophies, and establishing a diagnosis of hereditary retinal diseases - Follow-up norms; establish a network-based multi-center diagnosis and follow-up platform; obtain a biological sample library of hereditary retinal diseases mainly in China. The research will further improve and enrich the genotype, phenotypic characteristics and natural course of Chinese inherited retinal dystrophies, in order to promote the clinical evaluation of clinical inherited retinal dystrophies and the standardization of genetic diagnosis. It is also the evidence for the best timing for future gene therapy, to obtain the best therapeutic effect, and to provide a theoretical basis for achieving precise treatment.
