Background:

Current open-angle glaucoma management primarily targets intraocular pressure reduction.
Emerging research suggests augmenting current therapies with neuroprotective strategies.

Purpose of the Study:

To review recent advancements in molecular and cellular biology and neuropharmacology relevant to optic nerve damage in glaucoma.
To explore potential new therapeutic approaches for glaucoma management, including neuroprotection and nerve regeneration.

Main Methods:

Review of selected studies on excitotoxins, N-methyl-D-aspartate receptor antagonists, calcium channel blockers, nitric oxide, free radicals, nerve regeneration, and growth factors.
Analysis of molecular and cellular mechanisms underlying nerve damage in glaucoma.

Main Results:

Developments in understanding nerve damage pathways offer potential for pharmacologic optic nerve protection.
Research suggests possibilities for promoting the reversal of optic nerve damage.

Conclusions:

Future glaucoma therapy may involve strategies beyond intraocular pressure reduction, focusing on neuroprotection and regeneration.
Answering fundamental research questions could revolutionize glaucoma treatment paradigms.
