Bland\u2010Altman plots and repeatability and correlation analyses were calculated for both methods.<\/jats:p>\n <\/jats:sec>\n \n Results.<\/jats:title>\n There was a high correlation between both methods for ACD (r = 0.6144, p < 0.0001), VCD (r = 0.9595, p < 0.0001), and AL (r = 0.9290, p < 0.0001) but not for LT (r = 0.1604, p = 0.144). Measurements by OLCI were more consistent (smaller coefficients of variation and higher intraclass correlation). Bland\u2010Altman plots showed that ultrasound provided larger values for LT, VCD, and AL but not for ACD [differences between ultrasound and OLCI (mean \u00b1 SD): ACD = \u22120.11 \u00b1 0.12 mm; LT = 0.10 \u00b1 0.09 mm; VCD = 0.25 \u00b1 0.08 mm; AL = 0.50 \u00b1 0.16 mm].<\/jats:p>\n <\/jats:sec>\n \n Conclusions.<\/jats:title>\n A high correlation between both techniques was found for three of the four parameters (ACD, VCD, and AL). However, as the absolute values were different, both techniques cannot replace each other mainly because (1) one is non\u2010contact and the other contact and can induce a minor indentation of the cornea and (2) each device uses different types of waves that cross the ocular interfaces differently. While consistency and repeatability were better by OLCI, a disadvantage is that, different from humans, it can only be used in anesthetized chicks.<\/jats:p>\n
