Three low-viscosity perfluorocarbon liquids provided an intraoperative tool during vitrectomy to manage giant retinal tears. These clear fluids have a high specific gravity (1.8 to 1.9) and are immiscible with water. In six eyes, the giant tear was less than 180 degrees; in 11 eyes, it was 180 degrees or greater. In all eyes, the tear was unfolded and the retina was flattened while the patient was supine. The perfluorocarbon liquid was aspirated and replaced by air-perfluorocarbon gas mixtures (16 eyes) or silicone oil (one eye) at the end of the operation. The retina was reattached in 16 eyes (94%), with a minimum follow-up period of 6 months. In five eyes (29%), the retina was reattached without scleral buckling. Residual droplets of perfluorocarbon liquid were observed in four patients. These new materials complement present surgical techniques for managing giant retinal tears.
三种低粘度全氟碳液体在玻璃体切割术中提供了一种处理巨大视网膜裂孔的术中工具。这些清澈的液体具有高比重（1.8至1.9）且与水不混溶。6只眼中，巨大裂孔小于180度；11只眼中，巨大裂孔为180度或更大。在所有眼中，当患者仰卧时，裂孔被展开且视网膜变平。手术结束时，全氟碳液体被吸出，并用空气 - 全氟碳气体混合物（16只眼）或硅油（1只眼）替代。16只眼（94%）视网膜复位，最短随访期为6个月。5只眼（29%）视网膜在未行巩膜扣带术的情况下复位。4例患者观察到残留的全氟碳液体小滴。这些新材料补充了现有的处理巨大视网膜裂孔的手术技术。
