目的视网膜色素上皮的分离是黄斑移位手术中最困难的一步。为了完成这一关键步骤，我们开发了两种专门设计的连续流出针，一种用于制造视网膜脱离的刚性针和一种尖端柔软的全氟化碳液体注射针。设计：实验研究，新仪器开发。方法为了在视网膜与视网膜色素上皮分离过程中实现液体的连续流出，连续流出针的针轴直径小于20号，使液体能够从玻璃体腔中连续流出。结果该仪器已成功应用于54例黄斑移位合并360度视网膜切除术。刚性针头通过保持较低的眼压来创造安全的视网膜脱离，这是这一步骤所严格需要的。注射针便于注射全氟碳液体，同时用其柔软的尖端轻轻操纵视网膜。结论连续流出器在黄斑易位手术的关键步骤中发挥了重要作用。
PURPOSESeparation of the retina from retinal pigment epithelium is the most difficult step in macular translocation surgery. To complete this critical step, we have developed two specially designed continuous outflow needles, a rigid needle for creating retinal detachment and a liquid perfluorocarbon injection needle with a soft tip.DESIGNExperimental study, new instrument development.METHODSTo permit continuous outflow during separation of the retina from the retinal pigment epithelium, the shaft of the continuous outflow needle is smaller than 20 gauge in diameter to allow continuous flow of fluid from the vitreous cavity.RESULTSThese instruments have been used successfully in 54 eyes that underwent macular translocation with 360-degree retinotomy. The rigid needle creates safe retinal detachment by keeping intraocular pressure lower, which is strictly needed for this step. The injection needle facilitates injection of perfluorocarbon liquid while manipulating the retina gently with its soft tip.CONCLUSIONContinuous outflow instruments are useful tools because they facilitate critical steps in the delicate process of macular translocation surgery.
