Figure 4. Operative time used to treat RRD.
Twenty-four eyes diagnosed with RRD were equally divided into two groups. The mean operative time used to treat the first half (group 1, n=12) of RRD cases was 63.8±7.2min, which was significantly shorter than that (44.5±5.0min) used to treat the second half (group 2, n=12), P=0.04.
