Form deprivation myopia occurs when the eyesight is deprived by limited illumination and vision range, [78] or the eye is modified with artificial lenses [79] or deprived of clear form vision. [80] In lower vertebrates, this kind of myopia seems to be reversible within short periods of time.
Geographic atrophy (also called atrophic AMD) is an advanced form of AMD in which progressive and irreversible loss of retinal cells leads to a loss of visual function. There are multiple layers that make up the retina, and in geographic atrophy, there are three specific layers that undergo atrophy: the choriocapillaris, retinal pigment ...

Importantly, the axes and magnitudes of external and internal astigmatism do not necessarily coincide, but it is the combination of the two that by definition determines the overall optics of the eye.
