【摘要】　目的　探索顯微眼內窺鏡在后段眼內異物取出及玻璃體切除術中的應用。　方法　將2005年7月-2006年3月38例眼內異物患者分為試驗組（15例）及對照組（23例）。試驗組采用顯微眼內窺鏡下完成對外傷性視網膜玻璃體病變等的處理及眼內異物的取出；對照組采用顯微鏡直視下行常規玻璃體切割及眼內異物取出術。　結果　試驗組術后角膜透明度及眼壓恢復、視力提高及視網膜復位等情況均優于對照組；異物取出情況、手術時間和并發癥兩組無差異。　結論　在觀察困難或異物處于極周邊時應用顯微眼內窺鏡，能夠在手術中直接取出眼內各個部位異物，及時發現視網膜裂孔并同時行抗青光眼手術，減少對角膜材料的依賴和對角膜的損傷，為及時、準確和安全地手術提供了條件。
【Abstract】　Objective　 To investigate the application of the intraocular micro-endoscope in extracting intraocular foreign bodies (IOFB) and vitrectomy.　Methods　 A total of 38 patients with IOFB from July 2005 to March 2006 were divided into a trial group (15 patients) and control group (23 patients). The treatment for traumatic retinal vitreous lesions and extraction of IOFB were performed under the intraocular micro-endoscope in the trial group; while the conventional vitrectomy and IOFB extraction were performed under the microscope in the control group.　Results　 The degree of corneal recovery, improvement of intraocular pressure, visual acuity, and retinal reattachment were better in the trial group than that in the control group. There was no difference in removal of IOFB, surgical time and complications between the two groups.　Conclusion　 In patients with intraocular foreign bodies and cloudy cornea or other conditions that made the observation difficult, intraocular micro-endoscope is a useful convenience without relying on donated cornea. The practice made the judge of size, location and the distance more and more accurate through the monitor.
