曲安奈德吲哚青绿辅助玻璃体切割联合内界膜剥离治疗特发性黄斑裂孔

背景 视网膜内界膜剥离治疗特发性黄斑裂孔(IMH)的疗效是近年来争论的热点,安全、彻底地剥离内界膜手术操作难度较大. 目的 探讨曲安奈德、吲哚青绿辅助玻璃体切割联合内界膜剥离治疗IMH的疗效.方法 采用病例研究设计.收集IMH患者23例25眼进行标准经睫状体平坦部三切口玻璃体切割术.核心部玻璃体切割之后,后极部注射曲安奈德约0.1 ml.气液交换后保留约1/4的灌注液,将质量分数0.5％吲哚青绿0.2～0.5 ml于灌注液面下滴于黄斑裂孔处.术中观察内界膜染色效果,术后观察术眼黄斑裂孔闭合情况及视力改善情况.结果 25眼玻璃体后皮质及内界膜染色效果好,残余玻璃体及后皮质切除干净,内界膜剥离过程中瓣膜和边缘清晰可见.随访3～8个月,一次性手术裂孔完全闭合率为88.0％(22/25),部分闭合型占12.0％ (3/25).术后2个月最佳矫正视力(BCVA)为0.07～0.60,84.0％的患眼视物变形、眼前暗影明显减少或消失,52.0％的患眼视力提高. 结论 曲安奈德、吲哚青绿双染色辅助玻璃体切割联合内界膜剥离治疗IMH是安全、有效的治疗方法.

Tiamcinolone acetonide and indocyanine green-assisted vitrectomy combined with inner limiting membrane peeling for idiopathic macular hole

Background Whether the peeling of the inner limiting membrane （ILMP） increase the closure rate of idiopathic macular hole is still in controversy. Some ophthalmologist recommend vitrectomy combined with inner limiting membrane peeling for the treatment of idiopathic macular hole. However, the removal of ILMP is difficult because of its similar appearance to adjacent tissues. Objective This study was to investigate the efficacy of triamcinolone acetonide（TA） and indocyanine green（ICG） double staining-assisted vitrectomy combined with ILM peeling during the surgery. Methods A consecutive case-observational study was designed. The standardized vitrectomy was performed in 25 eye of 23 cases with IMH. During the vitrectomy, TA and ICG were injected into posterior pole vitreous to visualize and assist the ILM peeling. The dying effectiveness was observed, and the closure rate of macular hole, visual acuity, intraocular pressure and complications were evaluated after surgery. Written informed consent was obtained from each patient prior to operation. Results Posterior vitreous cortex and ILM were visible and the residual vitreous and cortex were removed clearly after dying of TA and ICG in all the 25 eyes. During the following-up duration of 3-8 months, the cumpietely anatomical reattachment of the macular area was in 22 eyes （88.0%） and partially rcattachment in 3 eyes（ 12.0% ）. The best corrected vision was 0.07-0.60 in all of the operated eyes 2 months after surgery. Conclusions TA and ICG-assisted vitrectomy combined with ILM peeling appears to be a safe and effective method for IMH repair.
