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
