The application of episcleral pockets in retinal detachment surgery is recommended for (1) eyes with large peripheral holes extending far posteriorly, (2) eyes with radially arranged groups of holes, (3) eyes with holes or tears in the midperiphery, and (4) as a combination method in eyes with one of the above lesions and changes in other parts of the fundus requiring an encircling procedure. During the years 1970 and 1971, a total of 68 patients underwent this operation. Success was achieved in 82% (56) on the first attempt. In 18% (12) the first operation was unsuccessful. The failures are analyzed carefully, and the technique that employs donor sclera to form the outer wall of the pocket and lyophilized dura mater as filler material is described.
