Purpose: To evaluate the effect of extrascleral cryocoagulation for the treatment of proliferative vitreoretinopathy (PVR) during retinal detachment repair.
Methods: Patients with a rhegmatogenous retinal detachment associated with peripheral PVR Grade C star-folds were included in this study and analysed retrospectively. In all patients, PVR star-folds were treated by extrascleral cryocoagulation.
Results: A total of six patients with a rhegmatogenous retinal detachment associated with at least one peripheral PVR star-fold were included in this study. Reattachment of the retina was successfully achieved in all patients.
Conclusion: This novel and simple technique for the treatment of localized PVR using extrascleral cryocoagulation appears to be a safe and effective approach with favourable surgical success rates.
