The second layer
of the eye: a layer of
blood vessels
They include iris and body Mahdb and choroid.
Iris Iris: a layer is not only colorful but that fibers and blood vessels. They contain rounded muscle work on pupil diameter stenosis (constrictor muscle of the pupil) that they do it if the light was shining so less light inside the eye. And receive directives from device Allasmbthaway which sends her nerve fibers with third cranial nerve.
There are other muscle working on expansion Albabo (extended muscle of the pupil), which responds to a sympathetic (or emotional) and work on the expansion slot pupil if the place was dark in order to increase the amount of light entering the eye. Well, it works if man is affected, for example, if his heart may love sympathetic because the device works to expand the pupil and increased heart rate and sweating.
The outer edge of the iris (the root) stick Pal sclera and ciliary body.
Called the iris and ciliary body together: anterior uvea.

In
front of and behind the iris no liquid water Aqueous humor, which is important
because it determines how the eye pressure is from the inside. He
is like a little thick water which fills the space between the iris and cornea
the anterior chamber of the Imam, and the iris and the posterior chamber lens
from behind.Working fluid in
the anterior part of the eye:Maintain eye pressure
to a certain degree.Maintaining
the cornea with a certain degree of concavity.Provide
food and oxygen to the lens of the eye and the cornea and carry
waste.Contains some
antibodies.Exam
question comes in: Since the cornea does not contain blood vessels (to remain
transparent) from where comes its food? Any
layer of the cornea is that absorb food and that it is important to maintain
them?
Do not mix liquid front watery fluid back thick gel because of the lens and the region around it acts as a barrier between the two.
Produces watery fluid in the rear compartment (between the lens and the iris) by the ciliary body especially from non-colored cells in the ciliary body. Then walking among the narrow space between the lens and the iris, then passes through the Strait of pupil, up to the front chamber between the iris and cornea. There it's time to return to the circulation of the blood and when it passes into channel Shalem place in front of the iris root is a network of veins which means the eye goes into circulation.
If you got a problem in the discharge of liquid water, it leads to increased internal eye pressure, either suddenly or gradually be chronically. Called Status: black water, or Alklakoma. GlaucomaReason not to discharge liquid water normally is either defect in the veins which pulls liquid water or due to blockage in the discharge area, this blockage occurs in the case of iris half expanded expansion Vtdguet roots on the drainage area is working to prevent discharges.If a sudden event the person feels terrible pain in the eye, and sees halos and Taatochoc vision because the cornea to swell. Here ambulance patient must immediately before damage occurs to the optic nerve.But if it stepped up the pressure gradually you will not notice the injured and Satlv optic nerve gradually due to increased pressure on him, and the first thing that fade is the vision that the remaining edges only central vision.If there is damage to the optic nerve can not repair the damage.So it must intervene first suspect in the disease by measuring eye pressure when an eye doctor and know whether natural or upward.
