What is a tear of retina?
The retina is a rip that occurs when harvesting eyeballs or "jelly" slips and pulls on the retina. When the eyes are subject to the natural aging process, the jelly that fills the rear cavity of the inner eye, begins to deteriorate and move. This type of movement causes aging eyes to be more susceptible to retina tears. If the retina tears occurs along one of the blood vessels of the retina, this can cause scratch bleeding. This bleeding is sometimes accompanied by a sudden shower of floats or flashes that can obscure vision.
Whether they obscure one's vision, acute tears of the retina expose the risk of loss of vision, as they allow the fluid to penetrate under the retina through the tears and can gradually raise the retina, causing the rhegmatogenic separation of the retina. Because of this risk, optometists and ophthalmologists will often monitor the eyes for the tear of the retina, which can be detected by expansion of pupils with special eye drops. Once it is detected, a tear of the retryoka can be sealed on the wall using lasers or cryotherapye (freezing). These procedures are usually painless and leave the scar on the back of the eye that seals the retina and prevents fluid leakage.
The retina is often not found without eye controls and eye tests, as its symptoms are painless. Such symptoms include the appearance of floats or flashes or flashes, which are caused by degeneration of the vitreous jelly into the liquid. Another symptom of retinal tears is the appearance of the shadow or curtain descending over one eye, which is often on the periphery and grows in size. A sudden reduction in the quality of vision can also indicate a tear of the retina.
If it is not treated, leaving the retina separation caused by the tears of the retina will lead to the retina losing nutrients transmitted by blood. As a result, the retina may lose its ability to function; In some Cases, permanently. Large retinal departments require surgical treatment while a small retina department can be repaired by the same laserThe way in which retina tears are sealed.
individuals who are short -sighted, underwent cataract surgery or experienced a head or eye, have an increased risk of tears or retinal separation. Also, patients who had a tear of retina in one eye have one chance to get retina in the other. In general, however, the retina separation is unusual and affects about one in ten thousand people.
