Figure 2. Orthographic projections. A: Orthographic azimuthal projection of the globe, polar aspect. B: Orthographic azimuthal projection of the globe, equatorial aspect. C: Orthographic projection of a lens, showing an oblique view of the anterior surface. The epithelium is arbitrarily divided into two regions: a spherical cap (yellow) and an equatorial band (blue). The number of cells in the spherical cap is calculated from cell counts made on a 60°-wide anterior sector (AS). The number of cells in the equatorial band is determined by cell counts made on a 10°-wide equatorial sector (ES). The border between AS and ES is marked by the position of a fiduciary, EdU-positive nucleus (red dot). See text for details.
