Glaucoma Overview: Glaucoma refers to a group of diseases that cause damage to the optic nerve. Containing more than a million nerve fibers, the optic nerve connects the eye to the brain. This important nerve is responsible for carrying images to the brain. The optic nerve fibers make up a part of the retina that gives us sight. This nerve fiber layer can be damaged when the pressure of the eye (intraocular pressure) becomes too high. Over time, high pressure causes the nerve fibers to die, resulting in decreased vision. Vision loss and blindness will likely result if glaucoma is left untreated.
I have known several older people with glaucoma, and I am glad that there will be a way to at least slow down the disease so that patients can keep their eyesight longer. In some cases, a patient would have gone blind and this new technology can help to preserve their eyesight, even if it means they will be able to see a few years longer than they would have been able to otherwise.
