过氟萘液体在治疗巨大裂孔视网膜脱离手术中的应用

巨大裂孔视网膜脱离手术中应用过氟萘液体（ｐｅｒｆｌｕｏｒｏｄｅｃａｌｉｎ）计１１例（１１只眼）。氟碳液体作为玻璃体手术中“液体操作”工具，具有稳定、平复视网膜后瓣，驱赶视网膜下液，便于进行增殖膜清除，以及直视下眼内激光封闭裂孔，其手术成功率为８１．８％（９／１１），失败者２例均为术前存在重度ＰＶＲ者，介绍了手术操作体会及要点。

Use of perfluorodecaliu in giant retinal tear retinal detachment surgery

Perfluorodecalin is used for the treatmen t of 11 eyes with giant retinal tear retinal detachment surgery. Perfluorocarbon liquids can be used as an operative hydrodynamic tool during vitre-ous surgery.The high specific gravity of perfluorocarbon liquids allows an easy unfolding of the inverted flap and flattening of the retina, displacing the subretinal fluid and stabilizing the retina for membrane peeling.Endophotocoagulation may be performed under optimal visual condition. The success rate was 81.8%(9/11). The retina failed to reattach in patients with advanced proliferative vitreoretinopathy.The surgical techniques were discussed.
