What is the Meaning & Definition of Glaucoma
Glaucoma is a disease that affects the eye and is characterized by the injury of optic nerve and retina, related to the increase of pressure within the eyeball. The eye is filled with fluid, the part that lies ahead of the Crystal contains a fluid and transparent fluid called aqueous humor, which is produced by a group of cells that form a structure called the ciliary body, liquid is formed in the back of the circular region that gives color to the eyes called iris He goes to the front through the pupil and it is drained by a series of channels that are located at the end of the Rainbow.
Under normal conditions there is a balance between production, dissemination and the drainage of the fluid, which leads to that the pressure inside the eye stays constant. When the liquid is not deleted in the same proportion that occurs has build up inside the eye, increasing its pressure which leads to the development of glaucoma.
The affectation of the vision begins with peripheral vision so often it starts without being perceived, it is possible that this disease start first in one eye and later affects both being able to evolve and leave sufferers it completely blind.
In the case of narrow angle glaucoma is possible that ocular redness accompanied by headache, eye pain, nausea, vomiting, alteration or sudden loss of vision.
Glaucoma increases its frequency from 60 years of age, when, for reasons that are not known well begin to clog the eye drainage channels leading to the increase in intraocular pressure. To diagnose it is necessary to carry out the measurement of eye pressure by means of a device used by ophthalmologists and optometrists.

Consequences of the elevation of intraocular pressure
The build up of aqueous humor in the eye produces pressure on the retina and the optic nerve, this leads to nerve fibers in the retina to degenerate which will progressively leading to loss of vision, which is an irreversible process.The affectation of the vision begins with peripheral vision so often it starts without being perceived, it is possible that this disease start first in one eye and later affects both being able to evolve and leave sufferers it completely blind.
Symptoms of glaucoma
There are two forms of glaucoma, the most common is the open angle glaucoma which does not produce symptoms, becomes evident when measuring the intraocular pressure during a routine eye examination either because the patient feels that it does not see well or that you have to turn your head to see some objects.In the case of narrow angle glaucoma is possible that ocular redness accompanied by headache, eye pain, nausea, vomiting, alteration or sudden loss of vision.

Glaucoma can occur from birth
There is a form of the disease known as congenital glaucoma, is due to the presence of congenital anomalies in the eye of type or as a sequela of infectious processes. It tends to occur during the first months of life, accompanied by alterations in the shape of the eye, opacity of the cornea, sensitivity to light and watery. This condition is treated with a combination of drugs and surgery.Article contributed by the team of collaborators.
