It is a patient-initiated registry accessible via a secure on-line portal at www.MyRetinaTracker.org. Affected individuals who register are guided to create a profile that captures their perspective on their retinal disease and its progress; family history; genetic testing results; preventive measures; general health and interest in participation in research studies. The participants may also choose to ask their clinician to add clinical measurements and results at each clinical visit. Participants are urged to update the information regularly to create longitudinal records of their disease, from their own perspective, and their clinical progress. The overall goals of the Registry are: to better understand the diversity within the inherited retinal degenerative diseases; to understand the prevalence of the different diseases and gene variants; to assist in the establishment of genotype-phenotype relationships; to help understand the natural history of the diseases; to help accelerate research and development of clinical trials for treatments; and to provide a tool to investigators that can assist with recruitment for research studies and clinical trials.",[26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53],"Eye Diseases Hereditary","Retinal Disease","Achromatopsia","Bardet-Biedl Syndrome","Bassen-Kornzweig Syndrome","Batten Disease","Best Disease","Choroidal Dystrophy","Choroideremia","Cone Dystrophy","Cone-Rod Dystrophy","Congenital Stationary Night Blindness","Enhanced S-Cone Syndrome","Fundus Albipunctatus","Goldmann-Favre Syndrome","Gyrate Atrophy","Juvenile Macular Degeneration","Kearns-Sayre Syndrome","Leber Congenital Amaurosis","Refsum Syndrome","Retinitis Pigmentosa","Retinitis Punctata Albescens","Retinoschisis","Rod-Cone Dystrophy","Rod Dystrophy","Rod Monochromacy","Stargardt Disease","Usher Syndrome",[55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82],"inherited retinal degenerative disease","retinitis pigmentosa","Usher","Leber","Bardet-Biedl","Batten","Best","cone dystrophy","cone-rod dystrophy","choroideremia","congenital night blindness","enhanced s-cone","cone monochromacy","Goldmann-Favre","Kearns-Sayre","Refsum","retinoschisis","rod-cone dystrophy","rod dystrophy","rod monochromacy","Sorsby pseudoinflammatory dystrophy","stargardt","achromatopsia","juvenile inherited macular degeneration","cone dichromacy","cone trichromacy","Charcot-Marie-Tooth","albipunctate dystrophy","RECRUITING","2026-05-18",{"date":86,"type":87},"2026-05-19","ACTUAL",{"date":89,"type":4},"2014-06",{"date":91,"type":21},"2037-06",{"name":93,"class":94},"Foundation Fighting Blindness","OTHER",1,{"id":97,"slug":98,"hasResults":11,"nctId":99,"briefTitle":100,"officialTitle":101,"acronym":102,"eligibilityCriteria":103,"healthyVolunteers":17,"sex":18,"minAge":4,"maxAge":4,"enrollmentInfo":104,"targetDuration":4,"studyType":23,"phases":4,"briefSummary":106,"conditions":107,"keywords":117,"overallStatus":83,"whyStopped":4,"lastUpdateSubmitDate":124,"lastUpdatePostDateStruct":125,"startDateStruct":127,"completionDateStruct":129,"leadSponsor":131,"locationsCount":95},"100599518","natural-history-study-of-inherited-retinal-diseases-100599518","NCT07085533","Natural History Study of Inherited Retinal Diseases","Color Vision Loss Progression in IRD Patients: Retinal Structural Changes Correlations, and a Novel Color Discrimination Test for Extreme Low Vision Patients","MojiLVCDT","Inclusion Criteria:\n\n1. Color Perception and Communication Ability Participants must have the ability to verbally identify or describe colors and test stimuli. This requires adequate cognitive and communicative capacity to understand instructions and respond appropriately during color vision testing.\n2. Diagnosis of Inherited Retinal Dystrophy (IRD Group Only) Participants assigned to the IRD group must have a confirmed clinical diagnosis of an inherited retinal dystrophy\n3. No Evidence of Inherited Retinal Disease (Control Group Only)\n\nParticipants in the control group must have:\n\n* No known history or clinical evidence of inherited retinal degeneration\n* Normal retinal health or only non-retinal ocular conditions not affecting retinal function (e.g., mild cataract, corrected refractive error)\n* Normal or expected-normal color vision\n\nExclusion Criteria:\n\n1.

Psychological or cognitive conditions affecting color perception or communication\n\n   * Severe developmental delays\n   * Cognitive impairments interfering with ability to comprehend or reliably perform color vision tests\n   * Psychiatric conditions that impair visual interpretation or reliable testing\n3.

The study will recruit approximately 200 subjects, encompassing a heterogeneous population of IRD patients-spanning a range of genotypes and clinical severities-as well as control participants devoid of retinal pathology. All enrolled individuals will undergo a standardized battery of evaluations, including quantitative color vision assessment, best-corrected visual acuity (BCVA) determination, and advanced multimodal retinal imaging.\n\nThe principal aim is to characterize the relationship between impairments in color discrimination and morphologic disruptions within the outer retinal layers, with particular emphasis on the continuity and reflectivity of the ellipsoid zone (EZ)-historically referred to as the inner segment\u002Fouter segment (IS\u002FOS) junction-assessed through spectral-domain optical coherence tomography (SD-OCT). Further, the study will explore associations between chromatic perceptual deficits and underlying genetic mutations, mutation patterns specific to IRD subtypes, and the influence of patient age on the severity and progression of color vision loss.\n\nA key secondary objective is the clinical appraisal and validation of a novel diagnostic modality, the Moji Low-Vision Color Discrimination Test (Moji Test), which is specifically engineered to quantify residual color perception in individuals with advanced central visual impairment. The test's discriminatory capacity will be benchmarked against established color vision testing paradigms to assess its reliability, clinical sensitivity, and suitability for implementation in populations with severe visual acuity reduction.\n\nBy incorporating a genetically and phenotypically diverse IRD cohort, the study is designed to enable granular, stratified analyses that will refine the understanding of structural-functional correlations in hereditary retinal disease. The inclusion of a control group with preserved retinal architecture and normal color vision function will provide essential normative baselines for comparative evaluation and statistical inference.",[108,109,110,111,28,112,113,114,115,116],"Retinal Dystrophies","Color Vision Defects","Vision Disorders","Macular Degeneration","Optical Coherence Tomography (OCT)","Visual Acuity","Genotype","Mutation","Phenotype",[118,119,120,121,122,123],"observational","IRD","ultra low vision","inherited retinal disease","color vision","color test","2025-12-03",{"date":126,"type":87},"2025-12-10",{"date":128,"type":87},"2025-07-20",{"date":130,"type":21},"2027-09-28",{"name":132,"class":133},"Zhongmou Therapeutics","INDUSTRY"]
