What is Avastin?
Avastin is a drug that can be injected into the eye for the treatment of wet age-related macular degeneration. Avastin was originally developed to treat various types of cancer, and works by blocking the growth of abnormal blood cells.
While Lucentis, a similar drug, is often administered in the treatment of wet age-related macular degeneration, many believe that Avastin is similarly effective and a much less expensive treatment option.
How does Avastin Work?
Avastin works by blocking the production of a chemical called “vascular endothelial growth factor” (VEGF). Wet age-related macular degeneration is caused by the growth of abnormal blood vessels in the eye, so by blocking this chemical Avastin can slow the growth of blood vessels that can leak and cause vision loss.
How does Treatment with Avastin Work?
Avastin is administered as an outpatient procedure. Your eye will be cleaned and an anesthetic is applied in order to numb the eye, and the drug is administered using a very fine needle. It is common to need repetitive treatment over time when using Avastin, as repeat treatments are typically necessary for continued results.
