PURPOSE
To present our experience with the removal of intraretinal foreign bodies.
MATERIAL AND METHODS
9 intraretinal foreign bodies were removed by pars plana vitrectomy. Laser photocoagulation of the retina surrounding the foreign body was performed either before surgery or intraoperatively (endolaser). Pars plana vitrectomy with foreign body removal through the sclerotomy site with endomagnet and/or forceps was performed. In some cases fluid-gas exchange was done.
RESULTS
The average follow-up period was 6.2 months. Seven of nine foreign bodies were magnetic and two were nonmagnetic. Five of seven magnetic foreign bodies had negative magnetic traction as the first surgical procedure. In these 9 eyes, final visual acuity was below 1/50 in 2 eyes and over 5/50 in 7 eyes.
CONCLUSION
Pars plana vitrectomy should be the method of choice in removal of intraretinal foreign bodies.
目的
介绍我们在视网膜内异物取出方面的经验。
材料与方法
通过玻璃体切除术取出9个视网膜内异物。在手术前或手术中（眼内激光）对异物周围的视网膜进行激光光凝。采用经巩膜切口用眼内磁铁和/或镊子取出异物的玻璃体切除术。部分病例进行了液气交换。
结果
平均随访期为6.2个月。9个异物中有7个是磁性的，2个是非磁性的。7个磁性异物中有5个在首次手术时采用了负性磁牵引。在这9只眼中，2只眼的最终视力低于1/50，7只眼的最终视力高于5/50。
结论
玻璃体切除术应是取出视网膜内异物的首选方法。
