折叠式人工玻璃体球囊植入严重视网膜脱离眼内的OCT特征

The OCT Imaging Characteristics of Foldable Capsular Vitreous Body Implanted in Eyes with Severe Retinal Detachment

目的:探讨严重视网膜脱离眼植入折叠式人工玻璃体球囊(FCVB)后光学相干断层扫描(OCT)呈现的特征。方法:系列病例研究。选择北京华尔医院2017年11月至2021年3月植入FCVB的严重视网膜脱离患者10例(10眼)。通过OCT进行术前,术后1周、6个月、1年、2年眼底检查,比较术前、术后OCT眼底检查结果,分析植入FCVB后视网膜复位情况。结果:眼底照片显示,植入FCVB的10眼中9眼能清晰看到眼底情况,1眼因角膜轻度混浊致眼底欠清晰。术后OCT检查发现,在10眼中视网膜前均约有200μm厚度的高反射光学条带,其中9眼黄斑中央凹结构正常,视网膜均基本复位,1眼未发现视网膜信号,同时发现FCVB囊膜与视网膜之间有较小的间隙,与视网膜贴伏良好。结论:FCVB植入后,OCT示视网膜前有特征性的高反射光学条带,与玻璃体腔和视网膜有明显区别,同时可以观察到视网膜的复位情况。

Objective:To explore the optical coherence tomography(OCT)characteristics of foldable capsular vitreous body(FCVB)implanted in eyes with severe retinal detachment.Methods:Serial case study.10 cases(10 eyes)with severe retinal detachment were selected for FCVB implantation in Beijing Huaer Hospital from November 2017 to March 2021.Preoperative and postoperative fundus examinations were performed by OCT in 1 week,6 months,1 year,and 2 years.To analyze retinal reattachment after FCVB implantation by comparing the preoperative and postoperative results of fundus examinations.Results:Fundus photography showed that the fundus was obviously visible in 9 out of 10 eyes with FCVB implantation,and was lack of clarity in 1 eye due to mild corneal opacity.Postoperative OCT examination was found that a high-reflective optical strip with a thickness of 200μm in front of the retina was in 10 eyes,the macular fovea structure was normal and the retina was basically reattached was in 9 eyes,and no retinal signal was found in 1 eye.At the same time,it was found that the gap between the FCVB capsule and the retina was small,and the retina was well attached by FCVB.Conclusions:After FCVB implantation,there is a characteristic high-reflective optical band in front of the retina,which is obviously different from the vitreous cavity and the retina.At the same time,the reattachment of the retina can be observed.
