VEGFA and polyp: Regarding the combination treatment of anti-vascular endothelial growth factor (anti-VEGF) and verteporfin PDT, a significantly higher effect on polyp regression was found with intravitreal ranibizumab combined with verteporfin PDT or verteporfin PDT monotherapy than with ranibizumab monotherapy in an EVEREST study that compared the treatment effects for 6 months.
