In patients suffering from a retinal detachment, the identification of all the breaks is crucial. In cases without any PVR, scleral buckling remains the first line treatment especially for ora dialysis or long standing Retinal Detachment (RD) linked to atrophic hole. However, the number, location and type of tears, the lens status will influence the selection of the treatment. The success rate is higher than 80% after one operation treated either with scleral buckling or pars plana vitrectomy but remains worse in pneumatic retinopexy. The main causes of failure are non identified retinal breaks and PVR.
