Anti-VEGF Medicines for Vision Problems
These medicines are injected into the eye by your doctor. Before the injection, your doctor will clean the area to prevent infection and numb the eye with eye drops to reduce pain.
How It Works
When wet age-related macular degeneration (AMD) develops, weak abnormal blood vessels grow under the retina and lead to vision loss. The growth of these vessels is triggered by a protein called vascular endothelial growth factor (VEGF). Anti-VEGF medicines block the effects of VEGF. Blocking this protein slows the growth of the abnormal blood vessels. This slows the vision loss linked to wet AMD.
Why It Is Used
Anti-VEGF medicines are used to slow the vision loss caused by wet AMD. These medicines slow the growth of abnormal blood vessels that leads to wet AMD. These medicines are also being studied to treat diabetic retinopathy.
How Well It Works
Anti-VEGF medicines can slow the vision loss that is linked to wet AMD.1 They may also improve vision for people with wet AMD.2 Because these medicines are relatively new, long-term effects are not yet known.
The common side effects of these medicines include:
Many side effects may be caused by the actual injection procedure rather than the drug itself. For example, the injections have a risk of infection.
Long-term effects of these medicines are not yet known.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
You will likely get the injections on a regular basis, such as once a month.
Other types of anti-VEGF drugs are currently being studied, including some that may be injected into a vein (intravenously) rather than into the eye.
Anti-VEGF medicines may help stop vision loss in people who cannot benefit from other treatments such as laser photocoagulation or photodynamic therapy.
