折叠式人工玻璃体球囊植入的初步临床实践

Preliminary clinical practice in implantation of foldable capsular vitreous body

目的:初步评价折叠式人工玻璃体球囊(foldable capsular vitreous body,FCVB)植入治疗严重眼外伤及复发性视网膜脱离导致的硅油依赖眼的安全性及有效性。方法:回顾性分析2017-11以来在我院施行FCVB植入患者4例4眼。其中男2例,女2例,平均年龄31.5岁,平均眼压5.6mmHg,严重眼球破裂伤术后硅油眼3例,复发性视网膜脱离术后硅油眼1例。对4例患者行玻璃体切除术和FCVB植入手术,术后观察患者的视力、眼压、视网膜和FCVB状态。结果:患者4例植入手术顺利,FCVB位置适当。术后随访1~3mo,视力无变化,平均眼压10mmHg,B超显示视网膜未脱离,FCVB回声平滑,未见排斥等并发症。结论:初步实践提示FCVB植入治疗严重的眼球破裂伤和硅油依赖眼安全、有效,可以很好地维持眼球形态和眼内压。

AIM:To evaluate the effects of foldable capsular vitreous body(FCVB) implantation on the treatment of severe ocular trauma and late silicone oil-dependent eyes due to severe ocular trauma and recurrent retinal detachment. METHODS:We retrospectively reviewed the four patients(four eyes) with FCVB implantation at our hospital since November 2017.Out of these 4 patients,2 were males and 2 were females,with an average age of31.5 years and an average intraocular pressure(IOP) of5.6 mmHg pre-operatively.Among those 4 eyes,3 eyes underwent silicone oil tamponade due to severe ocular trauma and the other one was recurrent retinal detachment in silicone oil-filled eye.Standard pars plana vitrectomy(PPV) was performed,and the FCVB was triple folded and implanted in the vitreous cavity of four eyes.The retinal was assessed,as well as visual acuity,IOP,FCVB condition before and after treatment,and applied therapy.RESULTS:All of those 4 eyes underwent successfully implantation of FCVB,which remained its proper position.During 1-3 mo follow-up,the mean visualacuity was no different compared with pre-operative values.However,the average IOP was 10 mmHg postoperatively.In addition,no retinal detachment was found using B-scan ultrasound after FCVB implantation.Moreover,FCVB-supported fundus was stable and no complication was found. CONCLUSION:FCVB implantation is a safe and effective method for the treatment of severe ocular trauma and late silicone oil-dependent eyes.It can maintain the morphology as well as IOP of those eyes.
