Cryogenic Retinal Treatment
Cryogenic surgery may be performed to seal retinal tears much in the manner that laser treatment is used. It is often used in conjunction of repair of retinal detachment with the injection of a gas bubble. It also may be helpful in treating benign ocular tumors. After using a local anesthetic, the cryoprobe is placed on the external wall of the eye. The probe gets very cold and a small freeze of the ocular tissues occurs around the tip of the probe. This will cause the tissue around a retinal tear to heal together and prevent a tear from developing into a detached retina. Cryogenic treatment is helpful in cases where laser photocoagulation may not be effective.
