The recognition of APVR and its dissection, along with the use of perfluorocarbon liquids, has greatly improved the success rate in surgery for severe PVR. In reviewing our first 71 cases using these techniques, 75% were attached with one operation and 90% were attached with one or more operations. These techniques have greatly improved our operative results and have obviated the use of retinal tacks and suturing, retinotomy (in most cases), and the need for very high scleral buckles. (We rarely alter an in-place scleral buckle.)
