To describe a novel technique for direct perfluorocarbon liquid (PFCL)-silicone oil exchange that aims to reduce the inherent risk of intraoperative intraocular pressure spike.
We use the conventional setup for passive PFCL-silicone exchange, but intentionally create a mismatch between the passive PFCL aspiration and the active silicone injection that favors the PFCL extrusion. This is achieved by converting one port to a large gauge one-23 or 20-gauge.
We did not note the occurrence of high intraocular pressure spikes with this technique as noted by disk pallor or attenuated vessels.
A hybrid 23/25-gauge technique for direct PFCL-silicone oil exchange is safe and reduces the risk of intraoperative intraocular pressure spike.
描述一种新的用于直接全氟碳液体（PFCL）-硅油交换的技术，旨在降低术中眼压骤升的固有风险。
我们使用被动 PFCL-硅油交换的常规设置，但有意地使被动 PFCL 抽吸和主动硅油注射之间产生不匹配，有利于 PFCL 挤出。这是通过将一个端口转换为大口径一 23 或 20 号实现的。
我们没有注意到这种技术会引起眼压骤升，如盘状苍白或血管变细。
直接 PFCL-硅油交换的混合 23/25 号技术既安全又降低了术中眼压骤升的风险。
