BACKGROUND Glaucoma drainage device (GDD) implantation in the anterior chamber are associated with corneal complications. We describe a novel technique to implant GDD tubes in the posterior chamber of pseudophakic eyes. METHODS Ten patients with glaucoma who required GDD tube implantation were included. RESULTS The new technique begins with the passage of one of two straight needles existing at each end of a 10-0 Polypropylene suture through the GDD tube. A 23-gauge needle then is inserted at an angle 180° away and passed from the anterior to the posterior chamber and finally through the sclera. The two suture straight needles from the 10-0 Polypropylene suture are positioned in the lumen of the 23-gauge needle. The 23-gauge needle is then extracted from the eye by passing the 2 needles through the lumen. The suture remains inside the posterior chamber, and the tube is inserted into the posterior chamber by pulling on the suture from the other side. No intra-operative complications were found such as bleeding, vitreous tube placement, bent tubes, etc. CONCLUSIONS: This surgical procedure to implant a tube into the posterior chamber of the pseudophakic eyes is uncomplicated and facilitates the insertion of the flexible tube into the posterior chamber. This eliminates the tendency of the tube to enter the vitreous as the tube is always placed in the posterior chamber away from the cornea.

在后房进行青光眼引流装置管的异体植入。

背景技术青光眼引流装置（GDD）植入前房与角膜并发症有关。我们描述了一种新技术，将GDD管植入假晶状体后眼。方法包括10例需要GDD管植入的青光眼患者。结果新技术首先通过一根10-0聚丙烯缝合线两端的直针之一穿过GDD管开始。然后将23号针头以180°的角度插入，并从前房进入后房，最后穿过巩膜。来自10-0聚丙烯缝合线的两根缝合线直针位于23号针的内腔中。然后，使2针穿过内腔，从眼睛中拔出23针。缝合线保留在后房内部，通过从另一侧拉动缝合线将管子插入后房。没有发现术中并发症，例如出血，玻璃管放置，弯曲的管等。结论：这种将管植入假晶状体后眼的手术过程并不复杂，并且有助于将柔性管插入后眼室。由于管总是放置在远离角膜的后房中，因此消除了管进入玻璃体的趋势。试用注册电流对照试验ISRCTN14276553（2019年5月31日）进行了追溯注册。没有发现术中并发症，例如出血，玻璃管放置，弯曲的管等。结论：这种将管植入假晶状体后眼的手术过程并不复杂，并且有助于将柔性管插入后眼室。由于管总是放置在远离角膜的后房中，因此消除了管进入玻璃体的趋势。试用注册电流对照试验ISRCTN14276553（2019年5月31日）进行了追溯注册。没有发现术中并发症，例如出血，玻璃管放置，弯曲的管等。结论：这种将管植入假晶状体后眼的手术过程并不复杂，并且有助于将柔性管插入后眼室。由于管总是放置在远离角膜的后房中，因此消除了管进入玻璃体的趋势。试用注册电流对照试验ISRCTN14276553（2019年5月31日）进行了追溯注册。由于管总是放置在远离角膜的后房中，因此消除了管进入玻璃体的趋势。试用注册电流对照试验ISRCTN14276553（2019年5月31日）进行了追溯注册。由于管总是放置在远离角膜的后房中，因此消除了管进入玻璃体的趋势。试用注册电流对照试验ISRCTN14276553（2019年5月31日）进行了追溯注册。
