Glaucoma Treatment

Glaucoma is a group of eye diseases that are characterized by a pressure that is too high for the optic nerve to withstand. The optic nerve is crucial in order, as is the nerve that sends all images created by the eye to the brain. Given its cruciality, nerve injury results from glaucoma first loss of peripheral vision and central vision.

Often, people with glaucoma do not even realize they have a problem because there are no obvious symptoms. The sight deteriorates gradually so that it is often overlooked. The only way to know that glaucoma is present by a physical examination by an eye doctor or optometrist may be able to see the problem by examining the eye with an ophthalmoscope.

Open-angle glaucoma (OAG) is the most common form of glaucoma in the United States and the United Kingdom. In open-angle glaucoma, the optic nerve is slowly damaged, usually causing gradual loss of sight. Both eyes can be affected simultaneously, although there may be more affected than others.

The problem of glaucoma is more in developing countries because of poverty, ignorance and the health system unsystematic. It is estimated that ten patients who visit the hospital eye has glaucoma and one in 100 becomes blind because of glaucoma in these countries.

The omega-3 docosahexaenoic acid DHA is important for healthy eyes and brain function. eicosapentaenoic acid EPA and alpha-linolenic acids are Omega 3 fatty and together are estimated to support good health. The omega-6 linoleic acid and arachidonic acid.

In addition to genetic inheritance, other factors that may predispose glaucoma myopia, diabetes mellitus, retinal vein occlusion, hypertension, intraocular tumors, cataract surgery and accidental injuries of the eye in the eye .

There are several types of glaucoma, the most common type is chronic open angle. There is also a kind Narrow Angle who is most common in nearsighted patients. Diseases like diabetes can cause the disorder and increasing the growth of blood vessels in the angle that drains fluid from the eye. This is the most dangerous and is called neovascular glaucoma and follows Rubeosis which is the growth of blood vessels in the iris of the eye.

It is estimated that nearly 67 million people worldwide are affected by this eye disease dangerous, and it should exceed 80 million within the next 10-15 years. In the U.S., according to "Prevent Blindness America, more than 3 million people have glaucoma, and only half of them are not even aware.

A technique popular laser surgery used for the treatment of glaucoma is called laser trabeculoplasty. This technique uses a highly focused laser beam to cut through the whites of your eyes and burn parts of the trabecular below. This causes the rest of the meshwork to expand, in effect, making it less dense and more permeable.

Alarmingly, the exact cause of glaucoma is not well known. For unknown reasons, blocking the passages (which flows through the eye) in the eye increases the pressure on the optic nerve and ganglion cells of the retina.
