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.
对于伴有玻璃体牵拉但无视网膜脱离的马蹄形裂孔，建议采用原发性巩膜环扎术并附加放射状巩膜植入物。手术开始时，在视网膜病变两侧的环扎缝线用2毫米硅胶棒稍作拉伸后打结。然后将放射状填充物置于环扎带下方。之后，将环扎带的其余部分无拉伸地收紧，并在交叉处用两根缝线固定。手术结束时，放射状植入物可用一到两根缝线固定以防侧向移动。整个手术过程辅以球后注射青霉素和地塞米松长效制剂。主要优点是消除了填充物定位和固定方面的任何困难，以及永久的加压效果。采用这种方法进行手术的37例患者中，未观察到并发症（随访时间为半年至2年）。该技术的禁忌症是房角狭窄。
