Among the various gases recommended for intravitreal injection, sulfur hexafluoride (SF6) and octafluorocyclobutane (C4F8) are the most commonly used. The purpose of the injection is to restore the vitreous chamber after drainage of subretinal fluid or after vitrectomy. Some of the fluorinated hydrocarbons which belong to the group known as Freon (a registered trademark) have previously been used in the animal with the same end in view. Of these, Freon-12 and Freon-114 were selected on account of their physical properties, the fact that they remain in the vitreous cavity for 4-14 days, their availability and their innocuousness, and used in humans as an adjunct to vitreoretinal surgery. The results are compared to those obtained with other halogenated gases.
在推荐用于玻璃体内注射的各种气体中，六氟化硫（SF6）和八氟环丁烷（C4F8）是最常用的。注射的目的是在视网膜下液引流后或玻璃体切除术后恢复玻璃体腔。一些属于氟利昂（注册商标）类别的氟代烃此前已出于同样目的用于动物。其中，氟利昂 - 12和氟利昂 - 114因其物理性质、在玻璃体腔中停留4 - 14天的事实、可用性和无害性而被选中，并在人类中用作玻璃体视网膜手术的辅助手段。将结果与使用其他卤化气体所获得的结果进行比较。
