摘要：

目的 评价强力磁铁吸取玻璃体内金属异物的效果。方法 70例患者（73眼）玻璃体内金属异物分为球壁异物、前段玻璃体异物和后段玻璃体异物，每类异物分别随机采用电磁铁仪（电磁铁组）或强力磁铁（强力磁铁组）吸取。电磁铁组球壁异物5眼，前段玻璃体异物18眼，后段玻璃体异物15眼；强力磁铁组球壁异物4眼，前段玻璃体异物17眼，后段玻璃体异物14眼。特斯拉计测量电磁铁仪和强力磁铁的磁通密度，比较两组各类异物取出率、取出所需时间以及取出术后并发症发生率。结果 电磁铁仪和强力磁铁在0~5 cm距离内磁通密度相近。两组各类异物取出率和取出所需时间比较差异无统计学意义（P>0.05）；两组各类异物取出术后白内障、玻璃体积血和眼内炎的发生率比较差异也无统计学意义（P>0.05）。结论 强力磁铁吸取玻璃体内金属异物的效果与电磁铁相当，但其更为经济实用。

Abstract:

Objective To evaluate the outcomes of removal of intravitreal metal foreign bodies with strong magnet. Methods Intravitreal foreign bodies in 70 patients (73 eyes) were divided into three categories, which were foreign bodies in the wall of eyeball, foreign bodies in the anterior vitreous body and foreign bodies in the posterior vitreous body. Foreign bodies in each category were randomly removed with electromagnet (electromagnet group) or strong magnet(strong magnet group). Electromagnet group included 5 eyes with foreign bodies in the wall of eyeball, 18 eyes with foreign bodies in the anterior vitreous body and 15 eyes with foreign bodies in the posterior vitreous body. Strong magnet group included 4 eyes with foreign bodies in the wall of eyeball, 17 eyes with foreign bodies in the anterior vitreous body and 14 eyes with foreign bodies in the posterior vitreous body. The magnetic flux density of electromagnet and strong magnet were measured by teslameter. The removal rate, time required for removal and incidences of complications after removal of each category of foreign bodies were compared. Results The magnetic flux density of strong magnet was similar to that of electromagnet at the distance of 0-5 cm. There was no significant difference in the removal rates and time required for removal of three categories of foreign bodies between two groups (P>0.05). There was also no significant difference in the incidences of cataract, vitreous hemorrhage and endophthalmitis after removal of three categories of foreign bodies between two groups (P>0.05). Conclusion The outcome of removal of intravitreal metal foreign bodies with strong magnet is similar to that with electromagnet, while the application of strong magnet is more economical and practical.
