What is cryotherapy?
Cryotherapy is the therapeutic use of cold temperatures to treat disorders of the eyes.

What eye conditions is cryotherapy used to treat?
Cryotherapy is used most often to treat retinal tears. The retina surrounding the tear is frozen, creating an adhesive scar around the tear that is quite similar to the scar created by a laser. It is used in a similar manner as part of pneumatic retinopexy or scleral buckling for treatment of retinal detachments.
