Criteria

Inclusion Criteria:

1. Patients give fully informed consent and are willing and able to comply with all study procedures.

2. In the study eye:

• Myopia of equal to or greater than -6.00D,and axial length ≥26.5mm.

• Diagnosis of active subfoveal, juxafoveal, or extrafoveal CNV secondary to high myopia.

• Visual impairment due to CNV secondary to high myopia.

• BCVA score ≥24 and ≤73 ETDRS letters (approximately 20/40~ 20/320 Snellen equivalent).

3. The BCVA score of fellow eyes ≥ 19 ETDRS letters (approximately 20/400 Snellen equivalent)

Exclusion Criteria:

1. Current vitreous hemorrhage in either eye.

2. Intraocular treatment with corticosteroids within last 3 months or periocular treatment with corticosteroids within last month in the study eye.

3. Active infectious ocular inflammation in either eye.

4. Fibrosis or atrophy involving the center of foveal in the study eye.

5. Any concurrent intraocular condition in the study eye that, in the opinion of investigator, could either require medical or surgical intervention during the study period to prevent or treat visual loss that might result from that condition.

6. The lesion size ≥30 mm2 in the study eye.

7. Any ocular disorder in the study eye that, in the opinion of the investigator, may confound interpretation of the study results.

8. Uncontrolled glaucoma or cup/disk ratio > 0.8 in the study eye.

9. Aphakia (excluding artificial lens) in the study eye.

10. Serious amblyopia and amaurosis in the fellow eye.
