Figure 4

Changes of visual level since baseline to 6 months after operation. The GEE analysis showed that average visual level improved after the operation, peaked at 2 weeks (), and kept stable in the following 6 months (). Visual acuity (VA) was stratified into the following categories: no light perception was scored as 0, light perception was scored as 1, hand motion perception was scored as 2, finger count perception was scored as 3, ≥20/400 was scored as 4, and ≥20/200 was scored as 5 [17]. The change of VA was significant from baseline to 2 weeks after the operation.
