    • Time Frame: at week 24
    • The proportion of subjects who decreased BCVA ≥15, ≥30 letters at 24 week compared with the baseline.
  • Change from Baseline in Central Retinal Thickness (CRT)
    • Time Frame: at screening;at week 4;at week 8;at week 12;at week 16;at week 20;at week 24
    • Change from Baseline in CRT as measured by Optical Coherence Tomography (OCT) over the study duration.
  • Change from Baseline in Choroidal Neovascularization (CNV) area
    • Time Frame: at screening;at week 4;at week 8;at week 12;at week 16;at week 20;at week 24
    • Change from Baseline in CNV area as measured by Optical Coherence Tomography Angiography(OCTA) over the study duration.

    • Time Frame: at screening;at week 4;at week 8;at week 12;at week 16;at week 20;at week 24
    • Change from Baseline in the number of PCV and BVN area as measured by Indocyanine Green Angiography(ICGA) over the study duration.
  • Change from Baseline in TCM(Traditional Chinese Medicine) syndrome scores
    • Time Frame: at screening;at week 4;at week 8;at week 12;at week 16;at week 20;at week 24
    • The title of the scale is Traditional Chinese Medicine Syndrome Scale.Compared wth baseline,the scores of changes of TCM syndrome evaluation at each visit .This scale consists of two primary symptoms: Blurred vision and Metamorphopsia,and four secondary symptoms.Four levels to measure severity of primary symptoms(0、2、4、6)and secondary symptoms(0、1、2、3) respectively. The final score has a range of 0(none)to 42(severe).TCM syndrome effect calculated by nimodipine method.The effect of TCM syndrome from negative (worsen) to 100% (disappear).
