Healthy volunteers: no

Brief summary:
This study aims to compare the efficacy of ranibizumab and verteporfin PDT combination treatment and verteporfin PDT monotherapy vs.ranibizumab monotherapy alone in achieving complete regression of polyps in patients with symptomatic macular polypoidal choroidal vasculopathy.

Detailed description:

Arms:
arm 1: Photodynamic therapy with verteporfin in combination with ranibizumab injection. Patients received one treatment at baseline with verteporfin photodynamic therapy (PDT) in the study eye and thereafter based on re-treatment criteria at intervals of at least 90 days. Within 1-24 hours, patients also received Ranibizumab intravitreal injection on Day 1 and at Month 1 and 2 and thereafter according to the re-treatment criteria at intervals of at least 30 days through Day 150. From month 3 onward, re-treatments were determined based on study-specific re-treatment criteria that included evaluation of polyp progression on indocyanine green angiography (ICGA), and assessment of fluorescein angiograms and visual acuity. arm 2: Patients received one treatment at baseline with verteporfin photodynamic therapy in the study eye and thereafter based on re-treatment criteria at intervals of at least 90 days. Within 1-24 hours, patients also received Ranibizumab placebo (sham intravitreal injection) on Day 1 and at Month 1 and 2 and thereafter according to the re-treatment criteria at intervals of at least 30 days through Day 150. From month 3 onward, re-treatments were determined based on study-specific re-treatment criteria that included evaluation of polyp progression on indocyanine green angiography (ICGA), and assessment of fluorescein angiograms and visual acuity. arm 3: Patients received one treatment at baseline with verteporfin placebo (with sham photodynamic therapy) in the study eye and thereafter based on re-treatment criteria at intervals of at least 90 days. Within 1-24 hours, patients also received Ranibizumab intravitreal injection on Day 1 and at Month 1 and 2 and thereafter according to the re-treatment criteria at intervals of at least 30 days through Day 150. From month 3 onward, re-treatments were determined based on study-specific re-treatment criteria that included evaluation of polyp progression on indocyanine green angiography (ICGA), and assessment of fluorescein angiograms and visual acuity.

Interventions: intervention 1: Verteporfin Photodynamic Therapy intervention 2: Ranibizumab
Intervention descriptions: intervention 1: After a 10-minute intravenous infusion of verteporfin at a dose of 6 mg/m\^2 body surface area, light application of 50 J/cm\^2 to the study eye was begun 15 minutes after the start of infusion. intervention 2: Ranibizumab at dose of 0.5 mg administered as an intravitreal injection.
