Fig. 1. The progression of intraocular pressure (IOP) elevation and electroretinography (ERG) amplitudes recorded from brief white stimuli after episcleral vein cauterization. (A) Diagram of the episcleral vein. (B) IOP changes from the age-matched control group and the glaucomatous group are plotted over time. The results are expressed as the mean IOP±the standard error of the mean (SEM) (n=6 in the control group and in each time group). (C) Representative waveforms of scotopic, photopic ERG in normal rat. (D–E) Scotopic ERG data are shown as the normalized amplitudes of a- and b-waves. (F) Photopic ERG is represented as normalized b-wave amplitudes over time. The results are expressed as the mean normalized amplitude±SEM (n=6 in the control group and in each time group). Significant differences at 1, 2, 4, and 8 weeks denoted as asterisk (^*) are from control vs. glaucoma groups. ^*p<0.05, ^**p<0.01, ^***p<0.001.
