Photodynamic Therapy for PDA in NV AMD

The purpose of this prospective observational study is to assess the potential clinical effects of adjunctive verteporfin photodynamic therapy (PDT) for persistent disease activity among patients with neovascular age-related macular degeneration (NV AMD). No specific interventions will occur as part of the study; participating subjects undergoing PDT as part of standard-of-care will be asked to consent to prospective collection of data from their medical records for up to five years from the date of consent, including results from ophthalmologic exams, imaging, and treatments. The primary study outcome will be the percentage of subjects with resolution of persistent disease activity at six months post-PDT treatment. Aside from a small risk of loss of confidentiality, risks associated with this study are no greater than those related to standard of care.
