This is a prospective, comparative control analysis. The investigators want to evaluate the aqueous humor levels of vascular endothelial growth factor in polypoidal choroidal vasculopathy and the effect of photodynamic therapy and combination treatment of photodynamic therapy and Lucentis (Ranibizumab)on the level of vascular endothelial growth factor.

To compare the effect of combination therapy of intravitreal injection of Lucentis™ and photodynamic therapy versus only photodynamic therapy on aqueous humor vascular endothelial growth factor level in polypoidal choroidal vasculopathy patients to establish the vascular endothelial growth factor expression after photodynamic therapy and the direct effect of Lucentis™ on this increased vascular endothelial growth factor level. Additionally the investigators want to examine the vascular endothelial growth factor , tumor necrosis factor alpha, interleukin-2, interleukin-6 and interleukin-8 level of aqueous humor in symptomatic, active polypoidal choroidal vasculopathy patients.
