EZ= ellipsoid zone; RPE= retinal pigment epithelium. Asterisk indicates a correlation coefficient that is not significantly different from zero. Area Central subfield is equivalent to 0.5 mm distant from the fovea is defined as central subfield and area. Central macula is equivalent to 1.0 mm distant from the fovea is defined as central macula..
