Background: The purpose of the present paper was to compare the techniques of conventional scleral buckling and combined pars plana vitrectomy and scleral buckling procedures in rhegmatogenous retinal detachments with unseen retinal breaks. Methods: Forty-four consecutive eyes with uncomplicated, primary rhegmatogenous retinal detachments with a clear media and unseen retinal breaks were randomized to two groups. The scleral buckling group underwent 360° scleral buckling, cryopexy and external subretinal fluid drainage. In the combined surgery group, 360° scleral buckling, pars plana vitrectomy, air-fluid exchange, endolaser and injection of 14% perfluoropropane gas was done. Results: At 3 months follow up the primary reattachment rate was 80% (16/20 cases) in the combined surgery group, and 70% (14/20 cases) in the scleral buckling group (P = 0.716). The visual, acuity improved significantly from a preoperative median of hand movement (HM; range: HM to 6/60; similar in both the groups), to a median of 6/60 (range: perception of light to 6/18) in the combined surgery group and a median of 6/36 (range: HM to 6/18) in the scleral buckling group, the difference between the two groups not being statistically significant (P = 0.4). The number of intraoperative and postoperative complications was more in the combined surgery group, (four cases were lost to follow up and were doing well when last examined.) Conclusion: Conventional scleral buckling was found to be a safe and effective technique in the primary management of uncomplicated, rhegmatogenous retinal detachments with unseen retinal breaks when the media is clear.
