Choroidal Neovascular Membrane
Choroid is an eye part which is present between the sclera and retina. It contains connective tissues and blood vessels. Choroidal neovascular membrane is a type of blood vessels which grow behind the retina in an area called choroid. These membrane break the layer between retina and choroid. They leak down on retina and cause vision loss and other serious eye conditions.
It is also associated with some other eye diseases. Wet age related macular degeneration is one of them. It is also found in patients suffering from myopic macular degeneration, eye injury and histoplasmosis.
One may experience painless vision loss and black spots in vision if he is suffering from this condition. The black spots appear especially in central vision and the vision appears distorted and irregular. Some of the other symptoms include: loss of color brightness that is different in both the eyes, flashing or flickering in central vision and objects will appear in different sizes in each eye.
This condition most commonly affects people who are more than the age of 50 as Wet age related macular degeneration affects people more than 50 years of age. People who have eye injury or other eye diseases at a young age can get this disease.
Diagnosis of Choroidal neovascular membrane
Using fluorescein angiography and optical coherence tomography, special photographs of the eye is taken by the ophthamologist. Cross sectional picture of the retina is created by OCT and it helps to detect abnormal blood vessels present in the eye.
