What is the retina?

The vein of the vein is a blood vessel that drains blood from the eye. It consists of a central vein that is drained into the structures around the eye and a series of smaller branches for collecting blood from the capillaries inside the eye. The corresponding artery that brings blood to the eye is known as a retinal artery. Problems with a vein retina are a very common cause of vision loss. During the routine eye test, the eye physician is usually checked on the patient's eye structure to see if there are problems with the vein or other components of the eye. The retinal vein leaves the eye with an optical nerve and can be emptied into the superior ophthalmic vein or into the cavernous sinus, depending on the structure of the human vascular system. The most common problem of this vein is the occlusion of the retinal vein, where the vein becomes completely or partially blocked. This will lead to an increase in pressure inside the eye. Fluid can be built and patients may begin with visual problems. The persistent high pressure can cause glaucoma, resulting in loss of vision by damage to structures inside the eye.Sometimes the patient does not experience pain or discomfort in conjunction with occlusion. The first sign of the problem may be blurred or changed vision, a sign of sight damage.

In the occlusion of the retinal branch of the vein has one of the subset of the vein of the blocking, but the other branches still release properly. The pressure will accumulate more slowly because the drainage system of the eye is still functional. When the problem of central retina is the pressure, the pressure can increase very quickly, because no liquid cannot flow out of the eye, while the retinal artery continues to supply nutrient -rich blood into the retina and create the accumulation of fluid.

during the eye test, doctors perform a pressure test to see if the pressure inside the eye is too high, and also look into the back of the eye to check any problems with retinal or vein, optical nerve, retina and other structures. If the doctor identifies the problem, some subsequent testing will learn more about whatIt happens and why it is necessary for a doctor to develop a treatment plan to solve the problem. This may include medicines, dietary changes or surgery, depending on what is happening inside the eye.
