Photodynamic Laser Treatment for
Age Related Macular Degeneration

You and your doctor have decided that a treatment using the drug Visudyne
and a laser might help your eye. The medication is given by injection into a
vein. This is followed by a brief laser treatment. Visudyne therapy is
approved to help slow the loss of vision.

Visudyne is a light-activated, or photodynamic, drug. This is injected into a
vein then travels to the abnormal blood vessels in your eye. It is then
activated by a low energy laser. A reaction closes the abnormal vessels by
drying them up.

Multiple courses of therapy are often needed. The abnormal blood vessels
may not be fully closed off and leakage may recur.

People with a known sensitivity to this drug or who have porphyria should
not receive this medication. Liver damage is possible. Visudyne is
metabolized through the liver. If you have certain conditions, you may need
a dose adjustment or special tests to safely receive this medication. Before
receiving this medication, tell your doctor if you have liver or gall bladder
disease or if you are receiving radiation treatment.

The appointment will take 1 - 1 1/2 hours. We will check your vision and
dilate your pupil. Your height and weight will be checked to determine how
much of the drug needs to be given to you. You may need to have a
fluorescein angiography test done to check the blood flow in your retina.

An IV will be started and the Visudyne will be given over a period of 10
minutes. Following a short wait, the doctor will do the laser treatment lasting
83 seconds. There is no pain other than the needle prick to start your IV.
Before your visit, eat a meal, take your medicines and drink plenty of

Bring these to your appointment:
(and wear for 5 days if exposed to direct sunlight or bright indoor lights)
Dark sunglasses A tight-weave, light colored long sleeved shirt
Wide brimmed hat Socks and Shoes
Gloves Long Pants

You may want to have someone drive you home after your procedure but it
is not required. Visudyne may cause side effects that interfere with your
ability to drive or operate machinery. Be careful if you do drive or do
anything that requires you to be able to see clearly.

Avoid exposure to direct sunlight or bright indoor lights for 5 days as
your eyes and skin will be sensitive to such light.

Dental exams Surgical Operating Rooms
Tanning beds Pulse oximeters
Direct sunlight through windows
Bright indoor lighting such as halogen or fluorescent

You will not be harmed by ambient indoor lighting such as indirect
sunlight through a window or low wattage incandescent lighting.

We will put a wristband on you to remind you to stay out of direct sunlight.

You should not stay in the dark while you are indoors as this can actually
cause the drug to stay active in your body longer. Exposing your skin to
ambient indoor light will help inactivate the drug in the skin.

If possible, wait until sundown to do outdoor activities. If you must go
outdoors in daylight during the first 5 days after treatment, protect all parts
of your skin and eyes by wearing protective clothing and dark sunglasses.

UV sunscreens are not effective in protecting against photosensitivity

Side Effects:

The following occur in 10-30% of patients...

Injection site reactions: such as pain, swelling, inflammation, rashes,
itching or bruising.

Tell your caregivers if you feel any burning, pain or swelling at the IV site
when the medicine is injected. If Visudyne does leak outside your blood
vessel, there is no risk of severe tissue damage but the area must be
thoroughly protected from direct light until the swelling and discoloration
have faded in order to prevent a local burn. Cold compresses may be applied
to the injection site.

Visual disturbances: such as blurred or decreased vision, flashes of light
and visual field defects.
