Nitrate therapy may retard glaucomatous optic neuropathy, perhaps through modulation of glutamate receptors.
Nitrates have been a major part of the internist's pharmacopoeia for more than 100 years, predominantly for the relief of anginal symptoms. The effects of nitroglycerin on the eye and specifically on intraocular pressure has been investigated with diverse results. However, nitroglycerin may also serve to protect retinal ganglion cells against glutamate mediated toxicity--a form of cell death that may be critical in glaucomatous blindness. Consequently, we therefore sought to evaluate whether nitroglycerin preparations, taken for non-ophthalmic reasons, had an effect on glaucomatous damage.
