Glaucoma is a disorder associated with pressure in the eye, and is characterized by damage to the optic nerve, with consequent visual loss, initially peripheral, but potentially blinding if relentlessly progressive.
Pseudoexfoliative glaucoma, which follows pseudoexfoliation syndrome, is a type of glaucoma thought to be caused by the deposition of "pseudoexfoliative material" into the trabecular meshwork eventually resulting in "plugging" of the microscopic canals, with consequent pressure rise.
The mechanism of neovascular glaucoma is the development of neovascularization (new, abnormal vessels) in the angle of the eye causing obstruction to fluid egress via the trabecular meshwork (primary outflow pathway of the eye).

 glaucoma
Schulzer and Drance 1990 found, in a study of a group of glaucoma patients 55% of whom were of the "low-tension" variety (LTG), and wherein which study multivariate analysis of 51 bodily physicobiochemical variables was performed, that: 1) Two patient groups separated out on an axis of blood-flow variables.
However, if a fair range of instances of glaucoma manifestation is found to truly correlate to more systemic bodily imbalances, and the latter are found to have known convenient means of correction, then part of the glaucoma treatment problem is solved to some extent.
It is doubtful that correlation of a broad, semi-metaphysical category such as "immune-related diseases" to glaucoma is of much help, but some means of arresting the sort of glaucoma inflicted via whatever means is present in my instance would seem to be in reach through refinement of this more peripheral mode of attack.
