Glaucoma affects many millions of people worldwide. In the United States about 7% of the population 65 years and older is affected. Traditionally glaucoma is thought to be due to mechanical problems: either increased pressure on the optic nerve from some form of trauma, or decreased blood flow (ischemia) to the optic nerve. However, it has long been apparent that increased pressure throughout the eye only damages certain cells in the eye and that the drugs used to decrease the pressure, though sight-saving, do not completely stop the progressive visual loss. Current research offers an explanation for why drugs to decrease pressure are not as effective as they should be.

Glaucomatous Optic Nerve Disease (GOND) is increasingly thought of as a neurodegenerative disease rather than a simple mechanical problem. The same neurochemical events leading to neuronal cell death in ischemic optic neuropathy also occurs in glaucoma. There is still much to be learned about how glaucoma causes visual loss, but enough is already known for researchers in many laboratories to be on the hunt for ways to protect nerve cells from damage in GOND.
