Visudyne

Visudyne (also known as Verteporfin) is a medication used in the treatment of certain types of age-related macular degeneration (AMD), pathologic myopia, and ocular histoplasmosis. It is a type of photosensitizer used in photodynamic therapy (PDT).

Visudyne is administered intravenously and activated by light of a specific wavelength. This activation leads to the production of reactive oxygen species, which damage the abnormal blood vessels in the retina that are associated with conditions like AMD.
