To describe a modified ab interno technique for the tube implantation from a glaucoma draining device into the ciliary sulcus.
The modified ab interno technique was performed on four eyes of four patients.
After the plate was fixed, a 21G needle is inserted through a paracentesis 180° away from the tube position into the anterior chamber and advanced to the posterior chamber through the sclera; finally, the needle exits the eye, then the tube is inserted into the lumen of the needle. The tube is then inserted simultaneously as the 21G needle is pulled out so the tube is placed on the ciliary sulcus.
We report a simple and novel technique for the tube implantation from a glaucoma draining device into the ciliary sulcus, in which the tube is guided with a 21G needle from an accessory paracentesis in order to achieve a posterior placement of the tube.
描述一种改良的经内路方法，将青光眼引流装置的引流管植入睫状沟。
对 4 例（4 只眼）患者采用改良的经内路方法进行手术。
巩膜固定器固定后，在远离引流管位置的对侧角膜缘做一个 180°的切口，用 21G 针头穿刺进入前房，针头经巩膜穿入后房，最后针头从前房穿出，将引流管插入针管的管腔。然后，随着 21G 针头的拔出将引流管同时插入，使引流管置于睫状沟。
我们报道了一种将青光眼引流装置的引流管植入睫状沟的简单而新颖的技术，该技术使用 21G 针头引导引流管，以便将引流管置于后房位置。
