Glaucoma: what is

This eye disease appears gradually and no symptoms while it develops. Glaucoma is not treated properly it can lead to blindness. It is necessary to perform eye exams once a year to detect this problem in time, with the aim of preserving the view.
In order to understand glaucoma, we must first know how the human eye works. In the previous part of this organ is the cornea, the transparent part that protects the eye and allow light to enter. The iris is the part of color and that expands or contracts so that the pupil (the black Center) can or does not allow for clarity. Light aimed at lens and is focused on the retina, whose nerve fibers carry images to the brain via the optic nerve.
The front of our eyes is filled with clear fluid, intraocular fluid. Leaves the eye, from the pupil, to be later absorbed by the bloodstream. If this drainage is correct, the eye pressure will be at their normal levels. The internal pressure of the eye then depends on the amount of that flow. If the drainage system does not work as expected, this liquid will come out freely, without build up. Intraocular pressure can vary throughout the day, although it stays within an optimal range.

In almost all patients with glaucoma, the drainage system is plugged and fluid cannot exit. When it accumulates, it increases the internal pressure and damages the optic nerve, which is very sensitive, causing loss of vision, irreversible.
There is usually no symptoms until glaucoma is quite advanced. In this case, the patient is blurred vision, headache, pain in the eyes, nausea, vomiting, sudden loss of vision and appearance of halos of colors around bright lights.
