However, a specific high-dose formula of antioxidants and zinc may delay or prevent intermediate AMD from progressing to the advanced stage. The wet form of the disease can be treated with photodynamic therapy PDT and injections into the eye. Photodynamic therapy invloves the injection of a light-sensitive drug into the patient’s bloodstream.
