What is Byooviz?

Byoovizis a prescription eye injection is used to treat types of macular degeneration, macular edema and myopic choroidal neovascularization. Byooviz is vascular endothelial growth factor (VEGF) inhibitor that works by keeping new blood vessels from forming under the retina (a sensory membrane that lines the inside of the eye). Byooviz (ranibizumab-nuna) is from the class of medicines called anti-angiogenic ophthalmic medications.

Byooviz is an injection delivered into the vitreous humor of the eye (intravitreal) and is usually given once a month.

Byooviz is an interchangeable biosimilar to Lucentis (ranibizumab injection) that was originally approved by the FDA on September 20, 2021, and became an interchangeable medicine on October 3, 2023.

Byooviz is FDA approved to treat:

  • neovascular (wet) age-related macular degeneration (nAMD) a leading cause of vision loss and blindness for people aged 65 years and older
  • macular edema following retinal vein occlusion (RVO), this is fluid build-up due to blockage of veins in the retina.
  • myopic choroidal neovascularization (mCNV), a vision-threatening complication of nearsightedness.

How is Byooviz given?

Byooviz is given as an injection into your eye.

Your doctor will use a medicine to numb your eye before giving you the injection.

You will receive this injection in your doctor's office or other clinic setting.

For a short time after your injection, your eyes will be checked periodically to make sure the injection has not caused any side effects.

Byooviz is usually given once every month.

Length of treatment and dosing schedules depend on the condition being treated.

Follow your doctor's dosing instructions very carefully. The timing of your monthly injections is very important for this medication to be effective.

To be sure Byooviz is helping your condition and is not causing harmful effects, your eyes will need to be checked on a regular basis. Do not miss any follow-up visits to your doctor.

Warnings

Call your doctor at once if you have sudden vision problems, eye pain or redness, or if your eyes are more sensitive to light.

Common questions about Byooviz

Biosimilars vs Biologics: What are they and how do they compare?
A biosimilar is a biological product that is similar to a reference biologic (usually the originally approved product) and for which there are no clinically meaningful differences in terms of safety, purity, and potency. On Sept 25, 2026, the FDA approved Degevma (denosumab-adet), a biosimilar to Xgeva (denosumab), making it the most recently approved U.S. biosimilar. Continue reading
What are anti-VEGF injections for macular degeneration?
Anti-VEGF eye injections are the main treatment for wet age-related macular degeneration (AMD), but they are not a cure. Eylea, Eylea HD, Lucentis, Vabysmo, Lytenava and Beovu are FDA-approved options, while Avastin is widely used off-label. These medicines can slow vision loss and may improve vision, but repeat injections are usually needed. Continue reading
