Prophylactic circumferential cryopexy: a retrospective study of 106 eyes.

A retrospective study of 106 eye which have undergone prophylactic circumferential cryopexy is presented. The complications involving the anterior segment were iritis, transient cycloplegia, as fixed dilated pupil, and cataract formation. Those involving the posterior segment were vitreous, subchoroidal and retinal haemorrhage, and preretinal fibrosis. The incidence of retinal detachment was 7.5% (8/106) after an average follow-up of 33 months. The importance of a confluent cryopexy choroidoretinal reaction is demonstrated. The indications are reviewed and a rationale for the technique of application is proposed.
