Percentage of flow deficits (FD%), average size of FD (\u00b5m2), total area of FD (mm2) and number of FD were calculated in different CC slabs (automatic, 11\u201321\u00a0\u03bcm, 21\u201331\u00a0\u03bcm, 31\u201341\u00a0\u03bcm, 16\u201331\u00a0\u03bcm).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>There was a statistically significant difference in all parameters and all slabs analyzed, when comparing SS-OCTA versus SD-OCTA V1 and SD-OCTA V1 versus SD-OCTA V4.
