Graph shows mean preretinal Po2 measurements (in mm Hg) at days 0, 3, 6, 9, and 12 after surgery. The measurements taken from the oxygenation group (n = 10) were significantly higher than those from the sham treatment (n = 5) and the no treatment (n = 5) groups over the 12-day follow-up period (one-way ANOVA; P < 0.0001). Error bars represent 1 SD.
