It is furthermore provided with several tools for analyzing the measured data. The fundamental components consist of a fundus camera with CCD measuring camera attached and an advanced image-processing unit. The measurement range is from 90 microns, temporal resolution is 40 ms and measurement resolution is less than 1 micron. Systematic error of non-linearity is S < or = 1.6\%, reproducibility is given by variation coefficient: short term vcs = 1.5\%, long term vcl = 2.8\%.
