Limits of constriction in the treatment of retinal detachment

H. Lincoff, I. Kreissig and L. Parver

A constricting silicone band was added to 13% of local sponge buckle operations in this series. The purpose was to relieve circumferential traction or to maintain a high buckle. The inclusion of a cerclage did not require drainage of subretinal fluid. The rate of reattachment without drainage (42 of 50 detachments) is comparable to what might be expected if the subretinal fluid had been drained. Constriction was controlled and limited to between 10% and 25% of the circumference of the eye. Anterior segment ischemia requiring relaxation of the band occurred in two patients; scleral erosion did not occur.
