What is a central retina?
The central vein of the retina is a vein that drains blood from the eye so that it can return to the heart for reoxygenation. This vein is a very important part of the anatomy of the eye, because it is only avenue blood drainage, as well as the corresponding central retinal artery is the only source of fresh blood. Damage either vein or artery can lead to very serious problems, including permanent loss of vision. This is one of the reasons why regular eye tests are recommended in order to have problems in the eye before they become serious. Depending on someone's anatomy, the vein can connect with the superior ophthalmic vein that flows into the cavernous sinus, or the central retina can connect directly to the cavernous sino for drainage. Hence the deoxygenated blood, it works down into the heart and lungs, where it will be reoxygenated and recirculated.
Leadic, the most common problem with the central vein retina is occlusion, a fantastic way to say "blocking". Oblucks in central retinal vein are often caused by clots and arein associated with older patients. In some cases, occlusion leads to swelling, which may eventually cause the retina separation, and in others it gets rid of part of the eye of the oxygen, leading to a loss of vision because the cells die when they do not get enough oxygen.
When someone experiences a sudden and painless loss of vision, the central retina of the vein may probably be the culprit. Unfortunately, the treatment options are limited, because at a time when vision is lost, there was damage. The ophthalmologist may perform an assessment to determine the scope of damage and on the basis of the results of the treatment recommendations.
Some people are an increased risk of developing blockages in their central retinal veins. For example, individuals with clotting disorders are susceptible to the development of clots that can lead to occlusion. Diabetics are also threatened, as well as people with high blood pressure and people with a history of glaucoma. Patients in these risky SKUpins may be encouraged to regularly visit doctors to check the eye health to identify problems as soon as possible. If the intervention is provided soon at the occlusion of the central retinal vein, some vision may be maintained.
