This website attempts to illustrate the glaucoma axon severance hypothesis that the optic disc/LC may be sinking in glaucoma due to atrophy
​of the border tissue of Elschnig in both in HTG and NTG.  As a result, the prelaminar nerve fibers along with its vasculature are stretched and broken(severed) resulting in excavation and splinter hemorrhages in the disc, ​a mechanical failure.  In other words, the nerve fibers are being severed, not atrophied in glaucoma.  Glaucoma may not be an optic disc neuropathy but an axotomy- a paradigm shift.  You will find on this website the published articles and images in support of the sinking disc and severance of nerve fibers.
