Abstract

Objective To study the outcome of removal of intraocular foreign bodies (IFB) via limbus using 23-gauge (23G) vitrectomy. Methods A retrospective non-comparative interventional case series of 22 cases (22 eyes) fulfilling the inclusion criteria were enrolled. They underwent 23G vitrectomy for management of posterior segment IFB and followed up 6~12 months (8.31±1.70 months). Eyes with penetrating eye injury involving cornea or sclera, cataract associated with anterior and/or posterior capsule tear requiring cataract surgery and IFB diagnosed by CT scan were included. Main outcome measures included success in removal of IFB without enlarging sclerotomy, ability to preserve capsular which helping secondary intraocular lens (IOL) implantation, improvement in visual acuity and complications. Results All eyes underwent the successful removal IFB through limbus (100%). Second intraocular lens was implant in 19 eyes (86.36%). The visual acuity showed significant improvement except 4 eyes (81.82%). There were no sclerotomy-related complications. Conclusions 23G vitrectomy for removal of IFB via the limbus is an alternative approach for select cases. This method obviates the need for scleral port enlargement and reduces sclerotomy-related complications, and preserve capsular support for early visual rehabilitation by secondary IOL implantation. Key words: Intraocular foreign body; Vitrectomy; Clinical effects

23号玻璃体切除术并经眼缘去除眼内异物

目的探讨23号玻璃体切除术经眼缘清除眼内异物的效果。方法采用回顾性非比较性介入治疗，纳入符合纳入标准的22例(22只眼)病例。术后行23G玻璃体切除治疗后段IFB，随访6~12个月(8.31±1.70个月)。包括角膜或巩膜的穿透性眼损伤，需要白内障手术的白内障合并前和/或后囊撕裂，以及通过CT扫描诊断的IFB。主要观察指标包括:巩膜摘除成功，巩膜未扩大，晶状体囊保留能力，辅助二次人工晶状体植入术，视力改善及并发症。结果所有眼均成功通过角膜缘摘除IFB(100%)。第二次人工晶状体植入术19眼(86.36%)。除4眼(81.82%)视力改善外，其余均有明显改善。无巩膜切开术相关并发症。结论23G玻璃体切除术经晶状体缘切除IFB是一种可行的方法。该方法避免了巩膜孔扩大，减少了巩膜切开术相关的并发症，并为二期人工晶状体植入术早期视力康复保留了囊膜支持。关键词:眼内异物;玻璃体切除术;临床疗效
