How is laser photocoagulation used to treat wet macular degeneration?

ANSWER

Laser photocoagulation destroys leaking blood vessels that have grown under the macula and halts the leakage. Laser therapy is helpful for about 10%-20% of people with wet macular degeneration. Some vision loss may occur, because this treatment creates scar tissue that is perceived as blind spots; however, even more vision would be lost if nothing is done at all. Up to half of patients who elect laser therapy may need repeat treatments.
