Fig. 1From: Intracranial pressure and optic disc changes in a rat model of obstructive hydrocephalus Acute epidural intracranial pressure (ICP) elevation in obstructive hydrocephalic (OHC) animals compared to control animals. A Mean curves showing the postoperative mean continuous epidural ICP (dots representing ± SEM). B Raw ICP trace from the overnight continuous recording in an OHC animal (X-axis in hours and Y-axis in mmHg). C Epidural ICP values from each animal in both groups are plotted at day 0, 1 and 7 (mean is showed with SEM error bars, **** = p < 0.0001). D Epidural ICP correlated with the ventricular ICP values at day 7 (Pearson’s r = 0.89, p < 0.0001)Back to article page
