根据164例眼内异物摘出术(磁性122,非磁性42)。在现代检查和手术方法的发展和启发下,我们对玻璃体内异物摘出的定位和手术方法要点进行介绍。磁性异物摘出成功率99％,非磁性97.6％。关键是精确的定位和谨慎地手术,并注意选择适应问题。除正确的X光拍片外,超声波检查判断球内、球外异物很有价值。磁性异物用传统方法,中间质混浊用张效房方格定位,能看到异物用直接定位法,和视网膜脱离手术中破口定位一样。各定位方法相互补充,经平坦部玻璃体显微手术适用于传统方法不能摘出的异物病例,包括非磁性异物和包囊附着于乳头附近视网膜上的异物。我们建议用一只器材的玻璃体显微手术,在裂隙灯手术显微镜下操作,无需玻璃体切割,简便有效。经平坦部非磁性异物摘出术的主刀者应有显微手术技术经验,特予强调避免发生因异物摘出引起严重併发症。
According to 164 cases of intraocular foreign body removal (magnetic 122, non-magnetic 42). In the modern inspection and surgical methods and the development and inspiration, we outline the removal of intravitreal foreign body positioning and surgical methods are introduced. Magnetic foreign body extraction success rate of 99%, non-magnetic 97.6%. The key is precise positioning and careful surgery, and pay attention to choose to adapt to the problem. In addition to the correct X-ray film, ultrasonic examination to determine the ball, ball foreign body is valuable. Magnetic foreign body with the traditional method, the middle of the turbidity of Zhang room with square positioning, foreign body can see the direct positioning method, and retinal detachment operation in the same break location. The positioning methods complement each other through the flat vitreous microsurgery applicable to traditional methods can not be excreted foreign body cases, including non-magnetic foreign bodies and cysts attached to the nipple near the retina of foreign body. We recommend vitrectomy with a single device, operating under a slit lamp operating microscope, without the need for vitrectomy, which is simple and effective. The flat part of the non-magnetic foreign body removal of the surgeon should have the microsurgical technique experience, special emphasis should be given to avoid the occurrence of serious complications due to the removal of foreign body.
