If the detachment is caused by a tear in the retina, the surgeon usually uses a laser or a freezing probe to spot weld the retina firmly onto the RPE and underlying tissues and thereby seal the tear. If a laser is used, this is called laser photocoagulation; use of a freezing probe is called cryopexy.
