How Do Ophthalmic VEGF Inhibitors Work?

Reviewed on 6/23/2021

What are ophthalmic VEGF inhibitors and how do they work?

Ophthalmic VEGF inhibitors are medications that suppress the growth of abnormal new blood vessels (neovascularization) in the retina, and their permeability. Abnormal neovascularization can cause leakage of blood and fluids into the retina, scar the macula and affect vision.

Retina is the innermost layer of light sensitive tissue on the inside of the eyeball, which enables vision by sending signals through the optic nerve to the brain. Retina’s central part is the macula, which has a high concentration of photoreceptor cells and is responsible for central and color vision and fine details of images.

Ophthalmic VEGF inhibitors work by inhibiting the activity of a protein known as vascular endothelial growth factor (VEGF) that stimulates new blood vessel growth. Ophthalmic VEGF inhibitors are fragments of protein molecules that bind to VEGF and block their activity.

How are ophthalmic VEGF inhibitors used?

Ophthalmic VEGF inhibitors are solutions administered as intravitreous injections. Vitreous is a clear gel-like substance that fills the eyeball space between the lens and the retina. Ophthalmic VEGF inhibitors are used to treat neovascularization in the retina, macula, fovea (a tiny pit in the center of the macula) and choroid, the layer over the retina.
