Fig. 1From: Effect of interscalene block on intraocular pressure and ocular perfusion pressureChanges in intraocular pressure in the blocked and unblocked sides. Measurements were made before interscalene block (ISB) (0), 10, 20, 30, 60 min after ISB (10), (20), (30), (60) respectively. Vertical bars denote 0.95 confidence intervals. † Statistically significant comparisons between the blocked and unblocked sides within each measurement time 10th min p < 0.001, 20th min p < 0.001, 30th min p < 0.001, 60th min p < 0.001 (Paired Samples t-test, p < 0.05 was considered as statistically significant) ‡ Statistically significant comparisons with baseline within the blocked side, (Repeated Measurement of Variance analysis by Wilks’ Lambda test, p < 0.05 was considered as statistically significant)10th min (p < 0.001), 20th min (p < 0.001), 30th min (p < 0.001), 60th min (p < 0.001)Back to article page
