Changes in the best-corrected visual acuity (BCVA) in eyes with macula-off rhegmatogenous retinal detachment (RRD) following vitrectomy.

<p>The mean BCVA significantly improved with time (<i>P</i> <0.001); rapidly in the early postoperative period and more gradually in the later postoperative period (A). The improvement of the BCVA from that at preoperative to Week 2 was significantly greater than that from Week 2 to Month 12 (<i>P</i> < 0.001) (B). The final BCVA was not correlated with the preoperative BCVA (C), but was significantly correlated with that at Week 2 (<i>r</i> = 0.61, <i>P</i> <0.001) (D).
