It is well established that an IOP reduction improves, on average, the prognosis of all types of glaucoma. It is also known, however, that even an ideal IOP does not stop progression in all patients. The insight into the pathogenesis of glaucomatous damage leads to new therapeutic approaches. Whilst most of these new avenues of treatment are still in the experimental phase, others, such as magnesium, Ginkgo, salt and fludrocortisone are already used by some physicians. Blood pressure dips can be avoided by intake of salt or fludrocortisone. Vascular regulation can be improved either locally by carbonic anhydrase inhibitors or systemically with magnesium or with low doses of calcium channel blockers. A number of other food ingredients such as polyphenolic flavonoids occurring in tea, coffee, dark chocolate or red wine and anthocyanosides found in bilberries have potential antioxidative effects. The oxidative stress at the level of the mitochondria can be reduced by Ginkgo biloba. Experimentally, glaucomatous optic neuropathy can be prevented by inhibition of astrocyte activation, either by blockage of epidermal growth factor receptor or by counteracting endothelin. Glaucomatous optic neuropathy can also be prevented by nitric oxide-2 synthase inhibition. Inhibition of matrix metalloproteinase-9 inhibits apoptosis of retinal ganglion cells and tissue remodelling. Up-regulation of heat shock proteins protects the retinal ganglion cells and the optic nerve head.
