Furthermore, we showed that omega-3 supplementation specifically lowers vitreous levels of VEGF-A without influencing plasma levels of VEGF-A in patients with wet AMD who were receiving a bevacizumab pro re nata regimen. This is likely because AMD provokes a local rise in VEGF-A, and hence only vitreous, but not systemic, levels increase. The average time
from last injection in both groups being treated with bevacizumab was 8 weeks, without ABT-888 order any significant difference between groups 1 and 2 (Table). Although recent studies have demonstrated decreased systemic VEGF levels up to 4 weeks after intravitreal bevacizumab injection, our study did not show any significant difference between groups 1 and 2 (treated with bevacizumab) and group 3 (treatment naïve) at 8 weeks after their last anti-VEGF
injection.39 and 40 Therefore, our data suggest that omega-3 supplementation selectively lowers pathologic ocular VEGF-A in the retina, but not physiologic systemic VEGF-A. Long-term studies will be required to determine if the observed reduction in VEGF-A by omega-3- supplementation combined with anti-VEGF translates into lesser CNV progression or activity.
