过去,单独用后巩膜扣带或巩膜缩短术,或配合用透热、冷凝或光凝治疗黄斑裂孔引起的视网膜脱离。最近许多作者认为玻璃体牵拉可以引起黄斑或黄斑周围裂孔。基于这种理论,Gonvers等(1982)建议作睫状体平坦部玻璃体切割术联合玻璃体注气术。Blankenip等(1984)在近视眼患者中作玻璃体内注入气泡(SF_6)置换液化玻璃体,可暂时封闭黄斑裂孔,并使视网膜永久性复位。作者在7例病人中采用这项技术,现介绍如下。一、选例与治疗方法:7例近视眼患者
In the past, the scleral buckling or scleral shortening alone or in combination with retinal detachment caused by macular holes treated with diathermy, condensation or photocoagulation alone. Recently, many authors believe that vitreous traction can cause macula or macular perforation. Based on this theory, Gonvers et al. (1982) proposed vitrectomy with pars plana vitrectomy combined with vitrectomy. Blankenip et al. (1984) performed intravitreal gas bubbles (SF_6) replacement of liquefied vitreous in patients with myopia to temporarily block macular holes and permanently re-set the retina. The authors used this technique in seven patients and are presented below. First, the selection and treatment methods: 7 cases of myopia patients
