RCA & the AAO Present Retina Torn Cryopexy
Cryotherapy involves the application of a very cold probe to the outside of the eye. Because the eye wall is very thin, the freezing temperature is transmitted to the retina. As with a laser, cryotherapy can seal abnormal “leaky” blood vessels or seal retinal tears. This technique is often performed in conjunction with a procedure called pneumatic retinopexy during the repair of some retinal detachments. Patients usually require small anesthetic injections before cryotherapy is performed.
