Mouse peripapillary scleral area
The mouse peripapillary sclera, optic nerve head, and optic nerve in epoxy section. The sclera divides into two portions, one splitting off posteriorly to join the dura mater and one continuing directly to the ONH. We measured the scleral thicknesses in two areas, one just prior to the division, which is referred to as the outer peripapillary scleral thickness (solid line square) and one after the division, next to the optic nerve head, referred to as the inner peripapillary sclera (dotted line square; scale bar =100μm).
