  1. The data are shown as the mean ± standard deviation. Group 1, ILM peeling during SO injection surgery; Group 2, ILM peeling during SO removal surgery. †At each time point vs. baseline, paired t-test. ‡Group 1 vs Group 2, independent t-test. *P < 0.05, statistically significant. BCVA best-corrected visual acuity, ILM internal limiting membrane, IOP intraocular pressure, SOR silicone oil removal.
