PURPOSE: To evaluate the role of prophylactic scleral buckling procedure with pars plana vitrectomy for the removal of retained intraocular foreign bodies (RIOFB) in the prevention of postoperative retinal detachment. METHODS: In a prospective, clinical, controlled study, 28 patients with RIOFB without retinal detachment were randomly divided into two groups of 15 (group I) and 13 (group II) patients. All patients underwent a standard three-port pars plana vitrectomy with foreign body removal. In addition to this standard procedure, patients assigned to group I had a 360 degrees encircling scleral buckle placed at the time of surgery. Group II patients did not have any scleral buckling. All patients were followed up for an average period of 11.8 months. Both groups were comparable with respect to age, sex, duration of injury, nature of injury, and site, size and type of RIOFB. RESULTS: The retinal detachment rate was found to be 6.6% in group I and 30.8% in group II (P = 0.24). Prophylactic scleral buckling reduced the risk of retinal detachment by 24% but this was not found to be statistically significant. CONCLUSION:Prophylactic scleral buckle placement with parsplana vitreous surgery for RIOFB may reduce the risk of late onset retinal detachment. A larger study would seem warranted.
