What is the standard licensed intravitreal dose of aflibercept used for diabetic macular edema?
- A 0.05 mg in 0.05 mL
- B 0.5 mg in 0.05 mL
- C 1.25 mg in 0.05 mL
- D 2 mg in 0.05 mL ✓
Explanation
Aflibercept is dosed at 2 mg in 0.05 mL for diabetic macular edema, wet age-related macular degeneration and retinal vein occlusion. Ranibizumab is 0.5 mg in 0.05 mL and off-label bevacizumab is typically 1.25 mg in 0.05 mL, which are the classic distractor pair here. Aflibercept is a soluble VEGF trap fusion protein binding VEGF-A, VEGF-B and placental growth factor, giving it a longer intravitreal half-life than the antibodies.
