A method of coagulating the affected tissue by concentrating a strong beam of light and generating thermal energy. When it was first developed in 1946, it used sunlight, but in recent years, high-pressure xenon lamps and laser light have been used. It was originally used to block holes in retinal detachment, but is now also used to treat diabetic retinopathy, central chorioretinitis, and retinopathy of prematurity.
