国产重水在非磁性眼内异物取出术中的应用

Extraction of nonmagnetic intraocular foreign body with perfluorocarbon liquid

目的探讨国产重水在非磁性眼内异物取出术中的应用及其临床效果。方法对29例（33眼）非磁性眼内异物行玻璃体切除联合非磁性眼内异物取出术，术中注入重水协助眼内异物取出。结果29例（33眼）异物全部一次手术取出，术后未发生视网膜脱离。5眼术前合并视网膜脱离者，术后视网膜复位。6眼术前合并眼内炎者，术后得到有效控制。术后无一例重水残留。结论在玻璃体切除联合非磁性眼内异物取出术中使用重水可以得到较好的临床效果。

Objective To evaluate the role of perfluorocarbon liquids on surgery of nonmagnetic intraocular foreign body extraction. Methods Perfluorocarbon liquids was used in vitrectomy to facilitate the extraction of nonmagnetic intraocular foreign body on 29 cases （33eyes）. Results All nonmagnetic foreign bodies in 29 cases （33eyes） were extracted successfully. There was no retained perfluorocarbon liquids and no retinal detachment postoperatively, The retinas of 5 eyes, which had preoperative retinal detachment ,were reattached. 6 eyes which had preoperativ endophthalmitis were controled effectively, Conclusion Using perfluorocarbon liquids in vitrectomy for the extraction of nonmagnetic intraocular foreign bodies is an useful method.
