Information provided by:
Age related macular degeneration is the leading cause of blindness for people over 50 in the western world. Blood vessels which start to grow form a lesion in the back of the eye. Verteporfin may stabilize the disease, by closing the blood vessels. This study will assess the efficacy and safety of verteporfin in patients with occult only lesions.

Condition Intervention Phase
Age-Related Macular Degeneration Drug: Verteporfin for injection Phase 4

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-Label, Multicenter, Phase 4 Study of the Effect of Verteporfin for Injection Therapy in Subjects With Occult With No Classic Choroidal NeoVascularization Secondary to Age-Related Macular Degeneration
