How effective is Photodynamic Therapy (PDT) laser surgery?
PXE International - Eye Treatments and ProceduresThere is no clear-cut answer for this question.

Photodynamic Therapy (PDT) is being used more frequently, but it has never been studied formally in PXE.

Macular Degeneration (MacDegen.com) :: MacDegen.com is dedic...PDT consists of a two-step process: an infusion of a drug (in the form of a dye) over a 10-minute period, followed by light activation of the dye using a "cold" laser. In this procedure, a drug called Verteporfin (Visudyne?) is injected into your arm, not the eye. Verteporfin travels through the body's blood-vessel system. When it pools in the new blood vessel responsible for wet macular degeneration, the eye surgeon shines a light into the eye for 83 seconds.

This natural substance is applied topically and selectively absorbs into fast-growing epidermal cells, including photodamaged skin, sebaceous glands, and actinic keratoses. ALA is converted to a powerful photosensitizer, protoporphyrin IX. When activated a singlet oxygen is produced that destroys the target cell.Related Questions
