重硅油在复杂性视网膜脱离手术中的应用

微创玻璃体手术的快速发展,为视网膜脱离的患者带来福音.许多以前无法治疗的复杂性视网膜脱离得到解剖复位,术后视力得以提高.良好的玻璃体替代物对玻璃体手术的疗效及技术的改进具有非常重要的意义.目前临床上常用的硅油和长效气体( C3F8)比重都比水小,对下方视网膜脱离顶压不足,而且术后患者要保持俯卧体位.重硅油比重比水大,可以对下方视网膜产生有效顶压.本文就重硅油的理化性质、临床应用、治疗效果及并发症等作一简要综述.

Application of high-density silicone oil in complex retinal detachment surgery

The rapid development of miero-invasive vitrectomy bring the good news for the majority of patients suffering from retinal detachment. Many previously untreatahle complex retinal detachment could be anatomic reattached, postoperative visual acuity could be improved. Vitreous substitute for good efficacy of vitreous surgery and improvements in technology has a very important significance. Currently used materials, such as silicone oil and C3F8 were lighter in proportion than water, and postoperative prone position was necessary to maintain. The high-density silicone oil, can make an effective top pressure on the retina. In this review, the physical and chemical properties of high-density silicone oil, clinical application, treatment and complications were overviewed.
