Table 1. Results of the repeatability study for circumpapillary scans of the RNFL. For each of the five healthy subjects, five measurements were repeated after realignment. The thickness values are calculated from the entire circumpapillary scan while the retardation and birefringence values only consider areas of RNFL thickness > 100 µm. (Note that the birefringence values can therefore not directly be calculated from the thickness and retardation values given in the table). The results of the quotient method are given in blue boxes, the ones of the linear regression in orange boxes.
