You are describing wet macular degeneration. This occurs when blood vessels grow underneath the retina (similar to grass growing through cracks in the side walk). There is normally a protective layer between the retina and underlying blood vessels. In macular degeneratoin, this protective layer can get weak and develop cracks, allowing these blood vessels to come forward.
Fortunately, the new injection medications are the best treatment for it. Compared to 5-10 years go, many people did not have many options and blindness
was a very real possibility. The new injections can stablize the vision or limit the damage. In some patients, they are sometimes able to regain some vision.
So, wet macular degeneration is a difficult disease and losing vision even with treatment is a possibility, the eye injections have been very helpful in treating it and the best treatment we have to date.
