Intravitreal Injections: Anti-VEGF Treatment for Retinal Disease

Intravitreal injections deliver medication directly into the vitreous cavity of the eye. They are the primary treatment for wet age-related macular degeneration, diabetic macular edema, and retinal vein occlusion. Common medications include ranibizumab (Lucentis), aflibercept (Eylea), and bevacizumab (Avastin).

Procedure Overview

Intravitreal Injections: Anti-VEGF Treatment for Retinal Disease

When Is This Procedure Recommended?

Wet AMD with new blood vessel growth under the macula
Diabetic macular edema causing central vision swelling
Retinal vein occlusion with macular edema
Choroidal neovascularization from any cause
Proliferative diabetic retinopathy with new vessel growth
Persistent macular fluid despite other treatments

Procedure Details

VEGF (vascular endothelial growth factor) overproduction drives abnormal vessel growth
Hypoxia in the retina triggers new vessel formation
Diabetic changes to retinal blood vessels causing leakage
Age-related breakdown of Bruch's membrane in AMD
Retinal vein blockage causing pressure and fluid leakage
Inflammatory conditions stimulating choroidal neovascularization

Recovery & Expected Outcomes

Ranibizumab (Lucentis) — monthly or as-needed injections
Aflibercept (Eylea) — every 1-3 months depending on response
Bevacizumab (Avastin) — off-label but widely used, cost-effective
Brolucizumab (Beovu) — every 3 months after loading doses
Faricimab (Vabysmo) — dual-action, longer intervals possible
Procedure takes under 5 minutes under topical anesthesia
Monitoring with OCT scans to assess fluid response
