Filter by: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.
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).
Fundus autofluorescence imaging has become an important diagnostic tool in ophthalmology, guiding diagnosis and assessment of progression of retinal diseases. This study investigates the performance of optimized long-wavelength autofluorescence imaging. To achieve this goal, the investigators will determine an optimal long wavelength excitation light and investigate the autofluorescence signal intensity in normals and patients with different retinal diseases. The diagnostic performance of the long-wavelength autofluorescence will be evaluated by assessing sensitivity and specificity for diagnosing a variety of degenerative retinal diseases and by comparing it to conventional autofluorescence.
Objective perimetry can better monitor visual field defects in retinal dystrophy and Glaucoma patients than conventional subjective perimetry. The PLR ( Pupil Light Reflex to short and long wavelength stimuli should be significantly lower compared to healthy participants in areas of visual field defects in retinal dystrophy and Glaucoma patients.
