结局指标
主要结局
The best-corrected visual acuity (BCVA)
时间窗: 1 to 6 months
Acuity is a measure of visual performance. The eye exam seeks to find the prescription that will provide the best corrected visual performance achievable
Amsler test
时间窗: 1 to 6 months
The Amsler grid, consisting of evenly spaced horizontal and vertical lines, has been widely used since 1947 to test the metamorphopsia.
Central retinal thickness
时间窗: 1 to 6 months
Quantitative thickness measurements derived from the "fast macular scan" algorithm report retinal thickness at several locations including the center point, central subfield, and 4 inner and 4 outer zones of the macula.
次要结局
- Retinal sensitivity(1 to 6 months)
