Abstract
This invention relates generally to the field of pharmacotherapeutics and the use of photodynamic therapy ('PDT'). In particular, the invention provides a method for reducing or preventing the effects of inflammation arising from normal dose photodynamic therapy (PDT), which method comprises exposing a target tissue in a subject that has been treated with normal dose PDT treatment to low dose light having a wavelength absorbed by a photosensitizing agent used in said normal dose PDT treatment for a time sufficient to reduce or prevent the effects of inflammation arising from said normal dose PDT treatment. The method is particularly useful in reducing or preventing the effects of inflammation arising from normal dose PDT treatment of ocular tissues.
