Broad scleral buckle in the management of retinal detachments with giant tears.
One of us (T.R.S.) operated on 24 patients with 26 retinal detachments caused by giant tears between 1969 and 1975 with the use of a broad silicone implant and diathermy. Minimum follow-up was six months. The technique included a scleral dissection extending at least three circumferential rows of diathermy posterior to the folded edge of the retinal flap, up onto the ora serrata, and two hours of the clock beyond each end of the tear. The retina was intentionally incarcerated on the buckle when subretinal fluid was drained. Sixty-nine percent of the cases were successfully reattached. If those patients with radial tears extending from the circumferential tears to the disk were excluded, the success rate rose to 75%. Seventeen percent of the successful reattachments required a second scleral buckle operation. Giant tears with radial tears extending to the disk, tears greater than 180 degrees, and immobile posteriorly everted flaps were poor prognostic signs. Thirty-five percent of the eyes with giant tears and a detachment had other holes or tears in the retina of that eye.
