Fig 1. (a) Best-corrected visual acuity (BCVA) changes and (b) central macular thickness (CRT) changes after treatment in the vitrectomy group and the control group.

Fig 1

(a) This figure shows changes of best-corrected visual acuity (BCVA) in logarithm of the minimal angle of resolution (LogMAR; mean ± standard deviation) in the vitrectomy group (circle) and the control group (square). The improvement of visual acuity was significantly better in the vitrectomy group at every time point (P = 0.035 at 3 months, P = 0.003 at 6 months, P = 0.003 at 1 year, and P = 0.024 at final visit). (b) This figure shows changes of central macular thickness (CRT) (μm; mean ± standard deviation) in the vitrectomy group (circle) and the control group (square). The CRT of the vitrectomy group decreased steadily during the follow-up period, whereas the CRT of the control group fluctuated and repeated treatments were needed. There was no significant difference in the change of CRT between the vitrectomy group and control group.
