The minimal scleral buckling surgery for rhegmatogenous retinal detachment

Objective To analyse the clinical efficacy of the minimal scleral buckling surgery for rhegmatogenous retinal detachments(RRDs). Methods This retrospective study was performed on 165 eyes of 162 patients of rhegmatogenous retinal detachments (RRDs). All cases received the minimal scleral buckling surgery , which did not been perform subretinal fluid drainage and sclera buckling limited only to the area of retinal tears. Results In this research, Of the 165 eyes, retina in 156 eyes (94.55%) reattached after the surgery and the subretinal fluid in 154 eyes was completely absorbed within 1 week post operation. There were 4 eyes with superior globular retinal detachment reattached after pneumatic retinopexy, 4 eyes with complicated retinal detachment were performed pars plana vitrectomy, another 1 patient gave up therapy. The results showed that complications of this surgery were rare. Some cases (20 eyes, 12.12%) experienced transient high intraocular pressure and returned to normal after medical treatment in 3 to 5 days. There were no intraocular hemorrhage, infection or iatrogenic retinal incarceration. In 3 to 6 months post operation, the refractive state had no difference compared with preoperation. Conclusion the exocular minimal surgery is a kind of segmental buckling and nondrainage surgery. The complication is rare and reoperation rate is low, it is a reasonable surgery for retinal detachment. This surgery is primary suitable for globular rhegmatogenous retina detachment and those retinal detachment with PVR less then level C1.
