[Episcleral sealing with a safety-circlage in juxtabasal horse-shoe tear (author's transl)].

Primary cerclage with an additional radial episcleral implant is proposed for horseshoe tears with vitreous traction, but without retinal detachment. At the beginning of the operation, the two sutures of the cerclage on both sides of the retinal pathology are tied with a little stretch of the 2 mm silicone rod. Then the radial plombage is placed beneath the encircling element. Afterwards the rest of the cerclage is drawn up without stretch, and the site of crossing is fixed with two sutures. At the end of the operation the radial implant may be secured against lateral movements by one or two sutures. The whole procedure is aided by parabulbar injection of penicilline and a depot of dexamethasone. The main advantages are the abolition of any difficulties in the localization and fixation of the plombage, and the permanent buckling effect. In 37 cases operated in this way, no complications were observed (follow-up time 1/2-2 years). Contraindication to the proposed technique is a narrow chamber angle.
