Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Subjects voluntarily participate and sign the informed consent form;
• Age between 18-55 years old, gender is not limited;
• Clinical diagnosis of IRD caused by RLBP1 mutations;
• For the study eye, residual visual field within the 30° central field is tested using Program G or Program LVC on the Octopus perimeter;
• At screening, the blood pregnancy test result of females of childbearing potential (e.g., females who have not undergone surgical sterilization or less than 1 year after menopause) is negative. Male and female subjects of childbearing potential agree to use effective contraception throughout the study and for at least 12 months after dosing.

You may not qualify if:

• Opacity of refractive media or inability to dilate pupils in the study eye that significantly interferes with visual acuity detection, anterior segment or fundus assessment;
• Presence of diabetic retinopathy, retinal vein occlusion, pathological myopia, retinal detachment, or other conditions in the study eye that are assessed by the investigator as affecting the safety of the subject or the validity of the study;
• Active intraocular or periocular infection (such as blepharitis, conjunctivitis, keratitis, scleritis, etc.) in the study eye;
• History of vitreous hemorrhage in the study eye within 6 months prior to screening;
• Any intraocular surgery in the study eye within 3 months prior to screening;
• History of glaucoma in either eye；
• History of uveitis in either eye；
• Those with diffuse intravascular coagulation and obvious bleeding tendency (such as hemoptysis, hematemesis, severe purpura, etc.) within 3 months before screening;
• History of myocardial infarction, unstable angina, coronary revascularization, cerebrovascular accident (including TIA), history of other thromboembolic diseases (such as thromboembolic angiitis, pulmonary embolism, deep vein thrombosis, portal vein thrombosis, etc.), New York Heart Association (NYHA) grade ≥ II cardiac insufficiency, severe unstable ventricular arrhythmia, within 6 months prior to screening;
• Subjects with systemic immune diseases (including systemic lupus erythematosus, ankylosing spondylitis, rheumatoid arthritis, etc.);
• Diabetic patients with any of the following conditions: Known macrovascular complications or Glycosylated hemoglobin at screening（HbA1c）\>7.5% or Those who have received more than two oral hypoglycemic drugs or received insulin or GLP-1 receptor agonists therapies;
• Hypertensive patients with poor blood pressure control (defined as: systolic blood pressure ≥ 160 mmHg or diastolic blood pressure ≥100 mmHg when the subject is seated after receiving antihypertensive medication);
• Any uncontrollable clinical illness (such as severe psychiatric, respiratory and other systemic diseases and history of malignant tumors);
• Subjects with abnormal liver and kidney function: alanine aminotransferase (ALT)/aspartate aminotransferase (AST) ≥ 2 times the upper limit of normal; Total bilirubin ≥ 1.5 times the upper limit of normal, creatinine and urea/urea nitrogen ≥ 1.5 times the upper limit of normal;
• Subjects with abnormal coagulation function: prothrombin time (PT) \> upper limit of normal value of 3 seconds or activated partial thromboplasting time (APTT) \> upper limit of normal value of 10 seconds; Haemoglobin (HGb) \< 10 g/dL;
