Abstract
The invention relates to the use of reduced fluency rate PDT to treat neovasculature, particularly choroidal neovasculature (CNV). Reduced fluency rate PDT decreases the likelihood of molecular oxygen being the limiting factor in the photodynamic reaction so that the concentration of either photons (light intensity) or photosensitizer in the target tissue controls the photodynamic reaction.
