Twenty eyes were identified as the better eye (BE) and 19 eyes as the worse eye (WE). Fixation stability was quantified with the 95% bivariate contour ellipse area (BCEA), logarithmically transformed. Bland\u2010Altman plots were used to determine the 95% limits of agreement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      For MAIA, the 95% limits of agreement were \u00b10.84\u00a0log deg\n                      <jats:sup>2<\/jats:sup>\n                      for the BE and \u00b10.66\u00a0log deg\n                      <jats:sup>2<\/jats:sup>\n                      for the WE.
