What is laser photocoagulation?

Laser photocoag: Laser energy is focused light energy of one wavelength. The light is absorbed into the target that is known to absorb that wavelength of light well, sparing other structures. The energy then is transformed to heat in the target and that seals up the blood vessel by coagulating it.

Used for eyes: Laser photocoagulation is a procedure that is used to control seepage from a damaged macula or a broken blood vessel. A laser is used to seal and coagulate the tissue around the point of the leak. Laser photocoagulaton is helpful in treating many different types of eye diseases, especially macular degeneration and other types of retinal issues.
