Expanding, long-lived intraocular perfluorocarbon gas bubbles can make possible the repair of retinal detachments with holes or tears in the posterior pole. Vitrectomy is not necessary for injecting the gas. The patient should be prone in order to bring the gas bubble to the top of the visual axis. Four perfluorocarbon gases have the appropriate coefficient of expansion to provide adequate intraocular gas volumes by displacing the fluid vitreous. Volumes of 1 to 2 cc are sufficient. Intraocular space for these amounts can be obtained either by draining subretinal fluid or by injecting 0.6 cc of C2F6 (which expands 3.3x) without draining. If the patient cannot tolerate being prone, most of the fluid vitreous can be displaced with an intraocular injection of 0.9 cc of C4F10 (which expands 5x).
膨胀的、寿命较长的眼内全氟碳气泡使得修复后极部有孔或裂孔的视网膜脱离成为可能。注入气体无需进行玻璃体切除术。患者应俯卧以使气泡位于视轴顶部。四种全氟碳气体具有合适的膨胀系数，通过置换液体玻璃体来提供足够的眼内气体量。1至2立方厘米的量就足够了。这些量的眼内空间可通过引流视网膜下液或注入0.6立方厘米的C2F6（膨胀3.3倍）而不引流来获得。如果患者不能耐受俯卧位，大部分液体玻璃体可通过眼内注射0.9立方厘米的C4F10（膨胀5倍）来置换。
