This is an interventional treatment trial for Wet Age-related Macular Degeneration

Eligibility Criteria

45 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Signed informed consent form;
  2. Age≥45 years,≤80 years,male or femal;
  3. The study eye must meet the following criteria: Diagnosis of wAMD; Primary or recurrent active subfoveal or parafoveal choroidal neovascularization (CNV) lesions secondary to AMD; Total area of all types of lesions ≤12 optic disc areas(30mm2); Best-corrected visual acuity of the study eye 70 letters or worse(Snellen equivalent of 20/40 or worse); No optometric media opacity and pupil shrinkage.

  10. Previous intraocular or periocular injection of anti-VEGF or corticosteroid drugs (such as ranibizumab, bevacizumab, conbercept, aflibercept, brolucizumab, pegaptanib sodium, anecortave acetate, triamcinolone acetonide, etc.) in either eye within 3 months before the first administration;
  11. History of allergy to fluorescein sodium or indocyanine green;
  12. PLT≤100×109/L;thrombin time and prothrombin time exceed the upper limit of normal range (based on the laboratory normal value of clinical trial institution), and the abnormality is clinically significant according to the evaluation of the investigators;
  13. Abnormal liver and kidney function;
  14. Uncontrolled blood pressure control,systolic blood pressure≥160mmhg ,or diastolic blood pressure≥100mmhg;
  15. History of surgery within one month before the first administration, or current non-healing wound, ulcer, or fracture,etc;
  16. Patients with any of the following serious systemic diseases,such as serious mental, neurological, cardiovascular, respiratory and other system diseases and malignant tumors, systemic immune system diseases, diabetes mellitus with uncontrolled blood sugar(HbA1c>10%), disseminated intravascular coagulation and significant bleeding tendency;
