目的：分析23G/25G微创玻璃体切割术后发生眼内炎的危险因素。方法：回顾性分析2014年6月—2023年5月于中国人民解放军中部战区总医院行微创玻璃体切割术后，临床诊断为眼内炎患者(开放性眼外伤患者除外)的临床特征。结果：纳入8 955例行微创玻璃体切割术患者，其中11例微创玻璃体切割术后患眼发生眼内炎，发生率为0.12％。平均年龄(60.8±7.6)岁。11例其中，5例(45.4%)患者合并糖尿病；原发眼疾构成情况：黄斑疾病7例(63.6%)、增殖期糖尿病性视网膜病变继发玻璃体积血2例(18.2%)，视网膜裂孔继发玻璃体积血1例(9.1%)、视网膜脱离1例(9.1%)；术中联合行白内障手术3例(27.3 %)；术毕8例(72.7%)患眼玻璃体腔填充无菌空气，3例(27.3%)填充平衡盐溶液，术毕所有患者均未缝合巩膜穿刺切口；术后低眼压3例(27.3 %)。术后发生眼内炎的时间为(2.8±1.1)d。11例患者经过局部和全身抗感染治疗后炎症控制不佳，均再次行玻璃体切割术联合术中配置万古霉素液灌注，其中9例术毕玻璃体腔填充硅油，术后所有眼内炎得到控制，10例(91.0%)患者最终矫正视力有所提高。结论：微创玻璃体切割术后，免缝合的巩膜切口可能是病原微生物侵入眼内导致眼内炎的潜在途径。尤其要重视黄斑手术中玻璃体不全切除引起巩膜切口处发生玻璃体束综合征可能是术后发生眼内炎的危险因素之一。

Objective: To analyze risk factors for endophthalmitis occurred after 23G/25G minimally invasive vitrectomy. Methods: Retrospective analysis of the clinical characteristics of patients with endophthalmitis (except patients with open eye trauma) after minimally invasive vitrectomy in General Hospital of Central Theater Command(Wuhan,430064) from June 2014 to May 2023. Results: This study included 8,955 patients, of which 11 cases occurred endophthalmitis after minimally invasive vitrectomy, with an incidence rate of 0.12%. The average age was (60.8±7.6) years, and 5 patients (45.4%) were complicated with diabetes; The composition of primary eye diseases: 7 cases (63.6%) of macular disease, 2 cases (18.2%) of vitreous hemorrhage secondary to proliferative diabetic retinopathy and 1 case (9.1%) vitreous hemorrhage secondary to retinal fissure, 1 case (9.1%) of retinal detachment; During the operation, 3 cases (27.3%) underwent combined cataract surgery; After the operation, 8 cases (72.7%) were filled with sterile air in the vitreous cavity of affected eye, the other 3 cases (27.3%) were filled with equilibrium liquid,and sclera puncture incision was not sutured in all patients; 3 cases (27.3%) had low intraocular pressure after operation. The time for postoperative endophthalmitis to occur after operation was 2.8±1.1day. 11 patients had poor inflammation control after local and systemic anti-inflammatory treatments, and all underwent vitrectomy combined with intraoperative injection of vancomycin solution. Among them, 9 patients were filled with silicone oil in the vitreous cavity after the surgery. After the operation, all the endophthalmitis were controlled and final corrected visual acuity of 10 patients improved. Conclusions: Minimally invasive vitrectomy and suture-free scleral incision may be a potential way for pathogenic microorganisms to invade the eye and cause endophthalmitis. Particular attention should be paid to the ‘Vitreous Wick Syndrome’ at the scleral incision caused by incomplete vitrectomy in macular surgery, which may be one of the risk factors for postoperative endophthalmitis.

玻璃体切割术是目前临床上常见的眼科手术之一，其应用广泛，且具有良好的治疗效果，但术后仍会出现各种并发症，眼压升高便是其中常见的一种。玻璃体切割术后眼压升高的病因复杂多样，术前原发病的不同、术中处理方式的差异以及术后并发症均可引起眼压升高，根据不同的病因可以选用更合适的治疗方法。早期的眼压升高较易控制，主要采用药物及激光治疗，晚期眼压升高导致继发性青光眼则相对复杂，以手术治疗为主。该文主要对玻璃体切割术后高眼压的原因分析及治疗进展进行综述。

Pars plana vitrectomy is one of the common ophthalmic surgeries in clinic practice currently, which is widely used with good therapeutic effect. However, various complications may still occur after operation. Elevated intraocular pressure is one of common complications. The causes of postoperative ocular hypertension are complex and diverse. Elevated intraocular pressure could be caused by different preoperative primary diseases, intraoperative management methods,and postoperative complication. More appropriate treatment methods can be selected based on different causes. Early elevated intraocular pressure iseasier to control and is mainly treated with medicine and laser. Late elevated intraocular pressure leads to secondary glaucoma, which is relatively complex and mainly treated with surgery. This review mainly states causes and treatment progress of high intraocular pressure after vitrectomy.

玻璃体替代物是玻璃体切割术后的必需品，用于填充玻璃体腔，恢复玻璃体的支撑视网膜、屈光和细胞屏障等功能。严重眼外伤及复杂视网膜脱离引起的视网膜/脉络膜脱离，如选用传统的玻璃体替代物(如硅油)填充，部分患者会出现硅油依赖眼或眼球萎缩，眼球难以保全。折叠式人工玻璃体球囊(foldable capsular vitreous body,FCVB)是我国独立研发的挽救眼球的人工玻璃体，属于国际首创，可以精细模拟自然玻璃体的结构，恢复玻璃体的部分功能。目前临床研究证实FCVB不仅可以有效避免硅油的并发症，还可以维持后房空间，缓慢恢复睫状体的功能，从而治疗硅油依赖眼，阻止眼球进一步萎缩。该文综述了FCVB的研究背景、结构特点、临床应用和拓展研究进展。

Vitreous substitutes are necessary after vitrectomy to fill the vitreous cavity and restore the vitreous to support retinal, refractive, and cellular barrier functions. Severe ocular trauma-induced retinal/choroidal detachment filled with traditional vitreous substitutes (e.g., silicone oil) can lead to silicone oil-dependent eyes and ocular atrophy in some patients, making it difficult to preserve the eye. Foldable capsular vitreous body (FCVB) is an artificial vitreous body independently developed in China to save the eye, which is the first of its kind in the world and can finely simulate the structure of natural vitreous body and restore some of the functions of vitreous body. It has been clinically proven that it can not only effectively avoid the complications of silicone oil, but also maintain the posterior chamber space and slowly restore the function of the ciliary body, thus treating silicone oil-dependent eyes and preventing further atrophy of the eye. This article reviews the research background, structural features, clinical applications and extended studies of FCVB.

玻璃体视网膜疾病并发白内障患者行玻璃体切割术联合超声乳化白内障摘除术，即前后节联合手术，是高效的手术方式，而后囊膜破裂(posterior capsular rupture,PCR)是超声乳化白内障摘除术的术中并发症之一，能够及时、有效地处理PCR，稳定、安全地植入人工晶状体(intraocular lens,IOL)，对于顺利完成后段手术，减少术后并发症十分重要。本文将对前后段联合手术中后囊膜破裂的术中处理、以及IOL光学部夹持固定法植入IOL的手术技术要点进行总结。

Combined surgery of pars plana vitrectomy (PPV) and phacoemulsification is an effective and safe way for management of retinal diseases complicated with cataract. Posterior capsular rupture (PCR) is one of the common intraoperative complications of phacoemulsification, and it is thus very important to deal with it promptly and efficiently, and ensure the subsequent procedures of intraocular lens (IOL) implantation as well as PPV. We will summarize the key points of the surgical technique for management of PCR and capture of IOL optic during combined surgery.

随着微创玻璃体切除术(pars plana vitrectomy，PPV)的广泛开展和手术技术的提高，患者对手术后视觉质量的要求越来越高。白内障是PPV术后最常见并发症，而具有玻璃体切除史的白内障患者屈光变异大，预测难度高。本文综述了生物测量误差、人工晶状体屈光力计算公式选择以及有效晶状体位置预测等影响有玻璃体切除手术史的白内障患者术后屈光误差的主要因素，旨在为降低这一类特殊人群白内障术后屈光误差提供参考。

With the widespread application of minimally invasive vitrectomy and the improvement of surgical techniques, the demands of patients for better postoperative visual quality are increasing. Cataract is the most common complication after vitrectomy, whereas the refractive outcomes of cataract patients with prior vitrectomy are viable and difficult to predict. In this paper, the main factors affecting postoperative refractive error of cataract patients with a history of vitrectomy, such as biometric error, selection of intraocular lens calculation formulas and prediction of effective lens position, were reviewed in order to provide reference for reducing postoperative refractive error of this special group of cataract patients.

Objective: To investigate the influencing factors of compliance of patients with silicone oil tamponade after vitrectomy. Methods: A total of 100 patients with silicone oil tamponade after vitrectomy in Wuxi People’s Hospital of Jiangsu Province from January 2018 to December 2019 were selected by random sampling method.The general information, possible reaction, and compliance of face-down positioning (FDP) were investigated by questionnaire. SPSS 19.0 was used for statistical analysis. Results: There were significant differences in patients’gender, attention to disease and FDP compliance (P<0.05), but there was no significant difference between family support system and FDP (P>0.05). The main influencing factors of FDP compliance were dyspnea (84%), poor sleep (78%), the discomfort of shoulder and neck (10%); on the third day after operation, the main influencing factors were dyspnea (66%), low back pain (50%) and poor sleep (39%); on the fifth day, the main influencing factors were numbness of the limbs (70%), low back pain (87%) and poor sleep (30%), the discomfort of shoulder and neck (18%) and elbow pain (10%). Conclusion: The main factors that affect the compliance of patients are gender, self-awareness of the disease and discomfort caused by FDP. It is necessary to strengthen the identification of high-risk factors, and give symptomatic education and guidance at different stages of illness, to improve the compliance of patients to FDP.
