Photodynamic Therapy

Photodynamic therapy (PDT) is a kind of retinal laser treatment first approved in 2003 and currently used for a variety of diseases. PDT involves the infusion of a light-sensitive medicine (Visudyne) into your body through an IV, followed by the application of a laser to the retina, resulting in a sealing of the blood vessels in the treated area.

Avoid light exposure after PDT
Because Visudyne is light sensitive and because it is infused throughout your body, it is critical to avoid direct sunlight or bright light exposure to your skin for 5 days after PDT treatment. Bright light includes but is not limited to:
- Bright sunlight
- Tanning salons
- Halogen lighting in homes and offices
- Lighting used in dentist’s offices or surgery operating rooms
Please note that sunscreen is not effective in protecting your skin from a photosensitivity
reaction.

 

Skin protection after PDT treatment

Wear a long sleeved shirt and pants, gloves, a wide-brimmed hat and sunglasses after your
treatment. Make sure to bring these items with you to the PDT laser appointment so that
you can protect your skin as you leave the office and return home. Wear tight-knit, lightly
colored fabrics if possible.

 

Stay away from undraped windows or skylights while at home. If possible, wait until
sundown to do outdoor chores.
