Study Comparing Ranibizumab Monotherapy With Combined Verteporfin Therapy in Subfoveal CNV

Intravitreal ranibizumab has shown to increase average vision in patients with subfoveal CNV secondary to AMD. However, the treatment does not provide benefit to all patients and the treatment regimen requires monthly intravitreal injections. Ranibizumab is an anti-VEGF-A monoclonal antibody fragment. Verteporfin photodynamic therapy acts through occluding newly formed vessels. The combination of these therapies acting through different modes of action bears the potential to provide a more convenient and less frequent therapy while maintaining/improving the increase in vision improvement observed with ranibizumab monotherapy. The strategic goal is to evaluate whether intravitreal ranibizumab in combination with verteporfin photodynamic therapy is an effective, safe and convenient treatment for patients with subfoveal CNV secondary to AMD and explore potential advantages of such treatment compared to ranibizumab monotherapy

Inclusion criteria

• patients over 50 years, subfoveal CNV of any type secondary to age-related macular degeneration (AMD), no "macula-treatment for the last 30 days (e.g. with PDT, TA, Laser, Macugen®).

• the area of the CNV must occupy at least >50% of the lesion (total lesion size under 5400 microns in greatest linear dimension)
• Occult CNV:
