Eligibility Criteria
Inclusion Criteria:
- Signed informed consent form;

- In addition to AMD,there are other obvious eye diseases/conditions,such as pseudoexfoliation syndrome,rhegmatogenous retinal detachment,macular hole,diabetic retinopathy and diabetic macular disease which need to be treated;
- CNV caused by other causes other than wAMD, such as vascular stripe disease, ocular histoplasmosis, case myopia, trauma, etc;

- Previous intraocular surgery ,or laser therapy for wAMD(as photodynamic therapy,transpupillary thermotherapy,etc.) in the study eye within 3 months before the first administration;
- 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;
- History of allergy to fluorescein sodium or indocyanine green;
- 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;
- Abnormal liver and kidney function;
- Uncontrolled blood pressure control,systolic blood pressure≥160mmhg ,or diastolic blood pressure≥100mmhg;
- History of surgery within one month before the first administration, or current non-healing wound, ulcer, or fracture,etc;
- 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;
- Suffering from systemic infectious diseases requiring oral, intramuscular or intravenous administration;
- Pregnant, lactating women and the patients who can not take contraceptive measures.
