Photodynamic
therapy (PDT) is a treatment indicated for patients
with Wet Age Related Macular Degeneration. Your doctor can determine if
you qualify for PDT by fluorescein angiogram.
PDT uses a combination of Visudyne, a light activated drug, and
the light from a non-thermal laser (a laser that does not burn the retina).
Visudyne is administered intravenously, and after administration, the
IV is removed, and the non-thermal laser is directed on the abnormal blood
vessels, activating the visudyne within the eye. PDT is beneficial
in that it can destroy abnormal blood vessels from wet ARMD, without damaging
the normal tissues of the retina. The goal of Visudyne therapy is
to stabilize patient's vision. PDT will not restore vision lost to wet ARMD, but
treatment may confine and inhibit the progression of the disease.
Patients who have undergone PDT are advised to follow strict post operative guidelines. The Visudyne is administered through out the whole body, thus making the patient light sensitive for 5 days after the treatment. Any exposed skin to sunlight, or hallogen lights will cause a third degree burn.
