CRYOTHERAPY

Cryotherapy, also known as retinal cryopexy, involves the use of a small metal probe whose tip becomes extremely cold (-60 to -80°C). This technique is typically used to seal retinal tears and can be used interchangeably with laser photocoagulation explained in the previous section.

Cryotherapy

To perform cryotherapy, the retinal specialist applies the tip of the probe to the surface of the eye over the retinal tear. Freezing the tissue momentarily results in a thermal reaction much like that created using laser. Over several days, an adhesion forms sealing the retinal tear and avoiding the development of retinal detachment. Like laser photocoagulation, this is performed in the office as an outpatient procedure.
