This review shows that quantitative measurements of fundus reflectance can be described by models that explicitly incorporate anatomical and physical properties of the fundus tissue. Newer techniques examine the fundus in ways fundamentally different from conventional optics, and must be included in this approach of measurement and modeling. The importance of the “inner surface reflector” (ISR) for tomographic imaging warrants more study of its optical properties, particularly its directional reflectance. For example, because the surface of a glaucomatous optic disc can slope steeply into the cup, the directional reflectance of the ISR may affect its apparent topography and thus the reproducibility of measurements of cup size
