Anti-VEGF Treatment for Wet Age-Related Macular Degeneration
Anti-VEGF treatment is a way to slow vision loss in people who
have a condition known as “wet” age-related macular
degeneration (AMD).
AMD is the leading cause of vision loss in people 50 years or older
in the United States. This condition damages the macula, which is
located in the center of the retina and enables you to see fine
details clearly. You rely on your macula whenever you read, drive,
or do other activities that require you to focus on precise details.
A person with AMD loses the ability to perceive fine details both
up close and at a distance. This vision loss usually affects only
your central vision.
There are two types of AMD. About 90% of people with AMD have the
atrophic or “dry” form of AMD, which develops when the
tissues of the macula grow thin with age. About 10% have the exudative
or “wet” form of AMD. With wet AMD, abnormal blood vessels
grow underneath the retina. These unhealthy vessels leak blood and
fluid, which can scar the macula. Vision loss can be rapid and severe.
Researchers have found that a chemical called vascular endothelial
growth factor, or VEGF, is critical in causing abnormal blood vessels
to grow under the retina. Scientists have developed several new
drugs that can block the trouble-causing VEGF. These are referred
to as “anti-VEGF” drugs, and they help block abnormal
blood vessels, slow their leakage, and help reduce vision loss.
Treatment with the anti-VEGF drug is usually performed by injecting
the medicine with a very fine needle into the back of your eye.
Your ophthalmologist (Eye M.D.) will clean your eye to prevent infection
and will administer an anesthetic into your eye to reduce pain.
Usually, patients receive multiple anti-VEGF injections over the
course of many months. There is a small risk of complications with
anti-VEGF treatment, usually resulting from the injection itself.
However, for most people, the benefits of this treatment outweigh
the small risk of complications.
Anti-VEGF medications are a step forward in the treatment of wet
AMD because they target the underlying cause of abnormal blood vessel
growth. This treatment offers new hope to those affected with wet
AMD. Although not every patient benefits from anti-VEGF treatment,
a large majority of patients achieve stabilized vision, and a significant
percentage can improve to some degree.
