Fig. 1

An overlay and numbering scheme of the multifocal electroretinography (mfERG) hexagons and the microperimetry (MP) stimuli points. The hexagons (n = 19) selected for the analysis are marked by a circle in a. In b, these 19 selected hexagons are overlapped with the MP test points using the exact distances from the foveal center. Thus, four central test points on MP lie on the inner hexagon (red color), two test points lie inside each hexagon in the second ring (green color), and one MP test point lies inside each hexagon in the outer ring (brown color). The nomenclature of the hexagons is depicted in c, where the central hexagon is labeled as 1. The distances from the foveal center of the MP test points is shown in d
