AIM:To observe the therapeutic effect of scleral buckling procedure for old retinal detachment. METHODS:Totally 12 patients 12 eyes with old retinal detachment preoperatively were under slit-lamp,using three mirrors to locate the retinal breaks,performed scleral buckling under the microscope.According to the preoperative position of the breaks pre-scleral suture was set,viscous subretinal fluid was drained,retinal breaks closed by croytherapy,silicone implanted under prescleral suture,and some patients combined with encircling band,ligated scleral suture to fixation.Patients were followed up to observe the retinal reattachment. RESULTS:The initial surgical retinal reattachment rate was 100%in all patients. CONCLUSION:Reattachment of retina can be achieved in some patients with old retinal detachment who undergo simple scleral buckling procedure.
