Figure S1. Typical RNFL curve over the 256 sectors which illustrates the three registration points used for alignment of individual curves. M is the minimum of the curve in the vicinity of the initial sector (which due to periodicity may also be close to sector 256). P1 and P2 are the peaks on the right hand side and the left hand side of M, respectively, which are typically found in the neighborhoods of sector 59 and sector 212. In the new coordinate system the registration points M, P1, and P2 will be located at x_M=0,x_P1=59, and x_P2=212.
