PHOTOCOAGULATION THERAPY

Photocoagulation therapy is a method of treating detachments (tears) of the retina (the layer of light-sensitive cells at the back of the eye) with an argon laser. The high-intensity beam of light from the laser is converted into heat, which forces protein molecules in the affected tissue to condense and seal the tear. The purpose of …
