目的：探讨可折叠式人工玻璃体球囊(FCVB)在治疗严重眼外伤及硅油依赖眼中的有效性和安全性。

方法：回顾性分析2018-05/2019-10于我院住院因严重眼外伤及硅油依赖眼行FCVB植入的患者20例，作为观察组； 同时纳入我院既往严重眼外伤未行FCVB植入的患者10例，作为对照组。记录观察组及对照组中各病例的术前及术后视力、眼压、眼球突出度、眼轴长度、视网膜复位情况及有无发生并发症等，并进行为期1a的随访，比较观察组观察指标的变化，以及观察组与对照组观察指标的比较，以此来评价FCVB的有效性和安全性。

结果：观察组术后1a视力、眼球突出度、眼轴长度与术前无差异，眼压明显升高(P<0.05)； 对照组术前眼球突出度及眼轴长度与观察组相比更大，但术后随访1a与观察组相比则更小(P<0.05)，并且对照组术后1a眼球突出度与眼轴长度与术前基线相比也明显减小(P<0.05)。观察组病例中视网膜均贴附良好，且未出现硅油乳化、继发性青光眼、眼内炎等严重不良事件。

结论：可折叠式人工玻璃体球囊在严重眼外伤及硅油依赖眼的治疗中具有较好地防止眼球萎缩的效果，且安全性较高。

METHODS:A retrospective study. Totally 20 patients who were underwent FCVB implantation due to severe ocular trauma and silicone oil reliance conducted in our hospital from May 2018 to October 2019 were select as observation group, 10 previous severe eye trauma patients without FCVB implantation as control group. The visual acuity(VA), intraocular pressure(IOP), exophthalmos, eye axis length, retinal reattachment, and complications of preoperative and postoperative in observation group and control group were recorded. A 1a follow-up was carried out to compare the changes in the observation indicators of each group so as to evaluate the effectiveness and safety of the FCVB.

RESULTS: Before and 1a after operation, there were no statistically significant differences in VA, eyeball protrusion, and axial length of the observation group, but IOP was significantly increased. The preoperative eyeball protrusion and axial length of the control group were larger than those of the observation group, but they were smaller than those of the observation group during the 1a follow-up. The eyeball protrusion and axial length of the control group were also significantly reduced 1a after the operation compared with the preoperative baseline. Retinas were well attached, silicone oil emulsification, secondary glaucoma, endophthalmitis and any other severe adverse event were not even occurred in the observation group.

CONCLUSION:FCVB could effectively and safely prevent eyeball atrophy in the treatment of severe eye trauma and silicone oil dependent eyes.
