What is choroidal neovascularization?

choroidal neovascularization is a common problem of the eye, which includes abnormal collection of blood vessels in the protective layer of eye tissue called choroid. The condition is closely associated with macular degeneration related to age (ARD), although it can also occur in young people who suffer injury or eye infection. The loss of vision is likely if the problem is not immediately recognized and treated. Patients are often able to obtain part of their vision medicines or correction surgery.

The choroid is located just below the furthest layer of eye tissue. It consists of small blood vessels that supply new oxygen to the retina. The inner layer of the choroid, known as the Bruch membrane, also provides protection and suspension for the inner eye. Choroidal neovascularization occurs when new blood vessels are prolived in the choroid due to rupture or other abnormalities of the Bruch membrane. Doctors do not fully understand why they create new blood vessels, Tygh have identified several conditions that lead to their development.

Most cases of choroidal neovascularization are secondary to wet ARM, a condition that begins as a blood vessel under the retina, expands and exert pressure on the Bruch membrane, eventually causing irritation or rupture. Wet plowing will most likely affect people over 60 years of age. Some cases of choroidal neovascularization are the result of eye trauma, such as chemical burns or shards of a glass that has rooted into the eyes. Less commonly commonly, tumors, congenital defects, autoimmune disorders or infections that reach the eye can damage the membrane Bruch.

The best known physical symptom of choroidal neovascularization is a gradual deterioration of vision. Visual problems usually begin with slight blur and aiming with a focus directly forward. In addition, the eye may seem redder than usual as a blood accumulation and fluid in front of the retina. Without treatment, blood vessels may eventually push the retina orcause significant scarring on the underlying tissue, leading to overall and permanent loss of vision.

The eye physician may usually diagnose the condition of the procedure called fluorescein angiography. The physician first injects the fluorescent dye into the choroid and then leads the diagnostic image using a specialized X -ray machine. The dye penetrates blood vessels and indicates the results of the display, allowing the specialist to determine the nature and severity of the condition.

Treatment of choroidal neovascularization usually includes drug injections, laser surgery or combination of these two. The physician may inject medicines directly to the affected choroid to prevent further accumulation of new blood vessels. Popular non -invasive procedure called photodynamic therapy involves exposing the choroid of light waves with high intensity in an effort to remove blood vessels. In the case of severe choroidal neovascularization, the surgeon may be able to cut into choroids and manually consumer scars tissue. Results of treatment withThey differ depending on the severity and basic cause of the condition, but many patients are relieved after immediate care.
