FVP: fibrovascular proliferation; OP: operation; RD: retinal detachment; VA: visual acuity. Statistical analyses of noncontinuous variables were performed with chi-squared test as appropriate, and continuous variables were performed with two-sample 𝑡-test. ^∗𝑃 value of less than 0.05 was considered statistically significant.
