Figure 1. TBARS levels in terms of the biomicroscopic detection of a PVD. Patients with an evident posterior vitreous detachment (PVD) had significantly increased thiobarbituric acid-reactive substances (TBARS) levels compared to those without clear biomicroscopic signs of PVD (1.45±0.54 vs. 0.53±0.38 p=0.001). Data are shown as means ± standard deviation (SD): n=27 (PVD); n=15 (no PVD). ** p≤0.001.
