Objective To observe the effect of scleral buckling in microsurgery for the treatment of rhegmatogenous retinal detachment.
Methods Thirty-nine cases (39 eyes) of rhegmatogenous retina1 detachment were performed with scleral buckling by microscope.Under the surgical microscopy, draining subretinal fluid, the cryotherapy of retinal breaks and retinal degeneration, the preplacement of silicone and encircling were performed in turn. The recovery of the visual acuity and the intraocular pressure and retinal reattachment of the patients were observed after operation.
Results Thirty-seven cases (94.87%) got retinal reattachment in first surgical procedure. One eye got reattachment after an additional vitreoretinal surgery (pars plana vitrectomy combined with Phaco). There were no serious operative complications. The visual acuity was improved in 25eyes, the same as no change in 14 eyes. No eye’s visual acuity was lowered.
Conclusion The scleral buckling in microscopic surgery for the treatment of rhegmatogenous retinal detachment is magnification ,precise location of scleral sutures, identification and avoidance of vessels. The procedures are simple, convenient, easy to master, reliable, and safe. It is not recommended to be used on posterior retinal tear.
