玻璃体切除术摘出眼后段非磁性异物

目的评价经玻璃体切除术治疗眼后段非磁性异物的临床效果。方法回顾性分析经玻璃体切除术治疗62例(65眼)眼后段非磁性异物的临床资料。结果所有患者均一次手术成功摘出异物。术后视力情况:合并视网膜脱离者42眼,术后视力提高12眼(28.57%),无变化28眼(66.67%),视力下降2眼(4.76%)。未合并视网膜脱离者23眼,术后视力提高15眼(65.22%),视力无变化8眼(34.78%)。结论经玻璃体切除术可有效地摘出眼后段非磁性异物,但术后效果受异物长期眼内存留的影响而较差。未合并视网膜脱离者视力预后明显优于合并有视网膜脱离者。

Clinical analysis on extraction of non-magnetic intraocular foreign bodies in posterior segment by vitrectomy

Objective To evaluate the clinical results of old non-magnetic intraocular foreignbodies extraction in posterior segment by vitrectomy.Methods Retrospective review the clinical records of 65 eyes of 62 cases of old non-magnetic intraocular foreign bodies treated by vitrectomy,to approach the clinical results and prognosis of old non-magnetic intraocular foreign bodies extraction in posterior segment by vitrectomy.Results Using vitrectomy and non-magnetic intraocular foreign bodies extraction,foreign bodies were extracted in 65 eyes in one time,the achievement ratio was 100 %.Postoperative visual acuity:Visual acuiiy of 42 eyes with retinal detachment improved in 12 eyes(28.57%),28 eyes remained unchanged(66.67%) and decreased in 2 eyes(4.76 %).Visual acuity of 23 eyes with no retinal dctachment improved in 15 eyes(65.22%),8 eyes remained unchanged(34.78%).Conclusion Old non-magnetic intraocular foreign bodies in post segment can be extracted effectively by vitrectomy.But the visual result is influenced by stagnation.Postoperative visual acuity without retinal detachment is evidently better than one with retinal detachment.
