铁锈症眼玻璃体视网膜手术疗效分析

目的观察铁锈症眼玻璃体视网膜手术治疗的疗效。方法回顾分析玻璃体视网膜手术治疗眼后段磁性异物诱发眼铁锈症22例22只眼的临床资料。男性21例，女性1例；年龄6～54岁，平均年龄40岁。异物存留于眼内1个月～20年。手术前最佳矫正视力（BCVA）＜0.01者15只眼，0.01～0.15者5只眼，0.1～0.2者2只眼。玻璃体腔异物18只眼，眼球壁异物4只眼。并发白内障18只眼。合并视网膜脱离3只眼。12只眼联合环扎、硅油填充，7只眼联合环扎、C3F8填充。18只眼联合白内障摘除术。2只眼联合小梁切除术。结果 22只眼内异物均手术一次成功摘除。手术后视力增加20只眼，占90.9%，不变2只眼，占9.1%。BCVA＜0.1者7只眼，0.1～0.4者8只眼，0.5～1.0者7只眼。手术中并发症，视网膜裂孔并发局限性视网膜脱离2只眼；扩大巩膜切口，玻璃体腔积血2只眼。手术后并发症，并发白内障4只眼；黄斑下异物取出手术后3个月，硅油取出时再次发生视网膜脱离1只眼，再次硅油填充视网膜复位；C3F8填充后7 d继发视网膜脱离1只眼，再次硅油填充，手术后视网膜复位。随访结束时22只眼视网膜均在位。结论铁锈症眼玻璃体视网膜手术治疗安全、有效，可避免铁离子进一步释放，改善患者视功能。

Therapeutic effect of vitreo-retinal surgery on ocular siderosis

Objective To evaluate the therapeutic effect of vitreo-retinal surgery on oclular siderosis. Methods The clinical data of 22 patinets (22 eyes) with ocular siderosis due to the magnetic foreign body at intraocular postsegment were retrospectively analyzed. The patients aged from 6 to 54 years (average 40 years), including 21 males and 1 femal. The duration of the magnetic foreign body remained in the eye lasted for 1 month to 20 years. The preoperative best corrected visual acuity (BCVA) was <0.01 in 15 eyes, 0. 01-0. 15 in 5 eyes and 0.1-0.2 in 2 eyes. There was Intra-vitreous foreign body in 18 eyes and ocular wall embedded foreign body in 4 eyes; intraocular foreign body (IOFB) combined with cataract in 18 eyes; combined with retinal detachment in 3 eyes; scleral buckling combined with silicon oil filled in 12 eyes and C3F8 filled in 7 eyes. Cataract extraction was performed in 12 eyes, and 2 eyes underwent filtrating surgery. Results The IOFB was successfully removed by one-off surgery in 22 eyes. BCVA increased in 20 eyes (90.9%) and kept unchanged in 2 eyes (9. 1%), including<0.1 in 7 eyes, 0. 1-0.4 in 8 eyes, and 0.5-1.0 in 7 eyes. Operative complications involved retinal holes with retinal detachment in 2 eyes and vitreous haemorrhage secondary to enlarge sclera incision in 2 eyes. Postoperative complications included secondary cataract in 4 eyes, retinal detachment due to silicon oil removal 3 months after submacular removal of foreign body in 1 eye, and retinal detachment 7 days after C3F8 filling in 1 eye; the latter two eyes had reattached retina after another silicon oil filling. At the end of the follow-up period, retina reattached in 22 eyes. Conclusion Advanced modern vireo-retinal operation is ffective on oclular siderosis, which can avoid the release of Fe+ and improve the patients' visual function.
