Photocoagulation Therapy is a "hot laser" treatment. With the advent of newer therapies, very few "hot" lasers are performed. For years, photocoagulation was the only treatment available for wet AMD.
This laser treatment seals the abnormal leaking blood vessels in the retina and discourages their growth. However, because it is a thermal laser, it may also damage nearby healthy tissues, causing immediate loss of some vision. Because the newer treatments do not affect the healthy retinal cells, they are almost always used instead of photocoagulation.
