Photodynamic Therapy Versus Combination Therapy in Polypoidal Choroidal Vasculopathy: Changes of Aqueous Vascular Endothelial Growth Factor – Corrected Proof
Purpose: To investigate the influence of photodynamic therapy (PDT) and combination of PDT and ranibizumab on aqueous humor levels of vascular endothelial growth factor (VEGF) in polypoidal choroidal vasculopathy (PCV).Design: Prospective randomized clinical trial.Method: We included 20 eyes with treatment-naïve PCV and 20 eyes undergoing cataract surgery as controls. PCV eyes were randomized to treatment with PDT alone or to a combination of ranibizumab and PDT on the same day. During 3 months, retreatment was not performed. Aqueous humors were collected at baseline and at 1 week, 1 month, and 3 months after treatment in the PCV group and during cataract surgery in the (Read more...)
