Visudyne Treatment for Wet Macular Degeneration

Visudyne is a photodynamic therapy (PDT) that can be used to treat wet macular degeneration.  Visudyne therapy is light-activated drug that uses a cold laser to halt the development of abnormal blood vessels associated with wet macular degeneration.

With visudyne treatments, the drug is injected intravenously into the patient’s eye.  As it circulates through the bod, it accumulates in the abnormal blood vessels that have developed in the eye because of macular degeneration.  These blood vessels are responsible for causing the loss of central vision as they leak and bleed, causing damage to the macula.

The accumulation of visudyne is targeted by a cold laser, activating the drug.  This causes a reaction that destroys the blood vessels whereever there is an accumulation in the eye.  Once these abnormal blood vessels are destroyed, the damage to the macula associated with wet macular degeneration is slowed.

In recent months, the use of visudyne to treat wet macular degeneration has declined dramatically as rival treatments have become more prominent.  Drugs such as Lucentis and the off-label use of Avastin have become the main weapons in the fight against wet macular degeneration.
