Age-related macular degeneration (AMD) results in the formation of new blood vessels in the eye. The walls of these vessels leak fluid, which causes scarring in the surrounding tissue, resulting in reduced vision or loss of vision. Photodynamic therapy (PDT) alone has been used to treat AMD, but many retreatments are needed, which cause further damage to the already diseased area. Laser treatment to coagulate the fluid actually causes additional new vessels to form. However, the inventive method of treating patients with both PDT and laser coagulation surprisingly either improved vision, or prevented further loss of vision. Moreover, the combined treatment eliminated the need for retreatment, and did not generate new vessel growth. Laser coagulation and PDT may be administered within the same treatment session or either may be administered first and the other may be administered within ninety days.

A method and system for diagnosing and treating infection or disease, in which an individual takes a photograph of an infected or diseased area of a body using a camera connected to a microprocessor. The photograph is sent to a diagnosing center having a server with a second microprocessor and a database of photographs correlated with different diseases and infections. The second microprocessor scans the image received from the mobile telephone and compares it to the photographs in the database. If a match is found, the second microprocessor then notes the disease or bacteria corresponding to the matching photograph. The second microprocessor then searches the database for a treatment corresponding to the identified disease or bacteria. Once a treatment is identified, information regarding this treatment is automatically sent to the individual's microprocessor.
