Diathermic scleral retraction appears to be an efficient technique, with little aggressivity, allowing both scleral indentation and radial and circumferential shortening of the ocular wall. We compared experimental results of a diathermic technique with those obtained by other authors using infrared laser scleral photocoagulation. The large number of variables, especially IOP, complicates standardization, but the results of the two methods on cadaver eyes were found to be quite similar. Diathermic scleral retraction creates a buckle effect and a 10 to 30% scleral shortening. This retractile effect decreases with rising IOP. This method would appear to have therapeutic interest for the management of retinal detachments with anterior proliferation and for the treatment of residual detachments after prolonged tamponade with silicon oil. These techniques of scleral shortening necessitate other experimental studies to evaluate their effects in the long-term, but the absence of induced chorioepithelial lesions would indicate therapeutic applications.
透热巩膜缩短术似乎是一种有效的技术,侵袭性小,既能使巩膜压陷,又能使眼壁径向和周向缩短。我们将透热技术的实验结果与其他作者使用红外激光巩膜光凝术获得的结果进行了比较。大量的变量,尤其是眼压,使标准化变得复杂,但发现这两种方法在尸体眼上的结果非常相似。透热巩膜缩短术会产生扣带效应和10%至30%的巩膜缩短。这种可收缩效应会随着眼压升高而降低。这种方法似乎对治疗伴有前部增殖的视网膜脱离以及治疗硅油长期填塞后的残余脱离具有治疗价值。这些巩膜缩短技术需要其他实验研究来评估其长期效果,但未诱发脉络膜上皮病变表明其具有治疗应用价值。
