Ischaemic optic neuropathy in chronic simple glaucoma.

Recurrent disc hemorrhage does not increase the rate of visual field progression

“…The pathogenesis behind DH and their recurrence remains unclear. Some authors have suggested that DH are the result of a vasculopathic event at the rim that results in nerve fiber loss [22][23][24]. Another hypothesis suggests that rapid degeneration of the rim tissue results in stress on the microvasculature [12,18], resulting in DH.…”

Does the Enlargement of Retinal Nerve Fiber Layer Defects Relate to Disc Hemorrhage or Progressive Visual Field Loss in Normal-tension Glaucoma?

“…Some investigators 24,25 have suggested that DHs are the result of vasculopathogenic events at the rim, which result in RNFL loss. Another hypothesis 26 suggested that rapid degeneration of the rim tissue results in stress on the microvasculature.…”

Axial Length and Scleral Thickness Effect on Susceptibility to Glaucomatous Damage: A Theoretical Model Implementing Laplace’s Law

“…The etiology of low tension glaucoma is controversial [13,14]. The ability of IOP to create a retrodisplacement of the lamina cribrosa was already dem onstrated [15,16] but the tension (T) in the sclera and lamina cribrosa was not measured.…”
