Figure 8.

The retinal ganglion cell layer considered in different coordinate frames. The profile of the GCL along the horizontal meridian is modeled for eyes of varying axial lengths (myope 27.57 mm; emmetrope 23.58 mm; and hyperope 21.79 mm). This same set of profiles is plotted for three different choices of unit and coordinate frames. (a) GCL tissue volume per square degree of visual angle as a function of eccentricity in degrees of visual angle; (b) GCL thickness in mm as a function of eccentricity in degrees of visual angle; (c) GCL thickness in mm as a function of eccentricity in mm of retina. For the last of these, the extent of the plotted functions along the x-axis varies with eye size.
