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.

先天性白内障是严重影响婴幼儿视功能的疾病。随着白内障手术和人工晶体植入手术技术的发展，先天性白内障患者术后多可获得高质量的视觉康复。然而，如何更好防治手术相关的不良事件和并发症、先天性白内障伴随的其他眼部发育不良疾病的治疗以及形觉剥夺性弱视的治疗，仍然是先天性白内障手术后需要重视的临床问题。文章对先天性白内障摘除及人工晶体植入术后高眼压和继发性青光眼的发生、相关危险因素、治疗和预防的手段进行总结，以期进一步提高对先天性白内障术后高眼压和青光眼防治的认识，减少术后并发症对视功能造成的进一步损害。

Congenital cataract is a significant condition that profoundly impacts the visual function of infants and young children. Advancements in cataract surgery and intraocular lens implantation have enabled the achievement of high-quality visual rehabilitation after congenital cataract surgery. Nevertheless, effective prevention and treatment of surgery-related adverse events and complications, as well as managing other ocular dysplasia and form deprivation amblyopia that may arise in conjunction with the surgery, continue to pose important clinical challenges following congenital cataract surgery. This article provides a comprehensive overview of the occurrence, risk factors, treatment and prevention of high intraocular pressure and secondary glaucoma after congenital cataract and intraocular lens implantation. Its aim is to enhance the comprehension of preventive and therapeutic measures for high intraocular pressure and glaucoma after congenital cataract surgery, thereby minimizing potential postoperative complications and preserving visual function.

目的：评估硅油填充术后眼压对角膜内皮细胞的影响及变化特点。方法：选取2019年1月1日至9月30日在佛山市第二人民医院眼科中心行玻璃体切除联合硅油注射的患者共131名，分为高眼压组(n=80)和正常眼压组(n=51)。高眼压组术后任意一次测眼压>21 mmHg，正常眼压组术后眼压均≤21 mmHg。比较填充硅油前与取硅油时的角膜内皮细胞参数测量值。结果：高眼压组的平均眼压为20.79 mmHg，正常眼压组的平均眼压为14.70 mmHg(P<0.001)。取硅油时，两组角膜内皮细胞密度(corneal endothelial cell density，ECD)均明显减少，平均内皮细胞面积均明显增大(P<0.05)，高眼压组内皮细胞大小变异系数(coefficient of variation of endothelial cell size，CV)明显变大(P<0.05)。高眼压组ECD丢失率(6.3%)高于正常眼压组(3.5%)；其中，高眼压组中术后1~6周内的眼压升高(7.1%)、眼压≥40 mmHg(7.3%)对角膜内皮细胞影响最大。ECD丢失与眼压变化有显著相关性(r=0.176，P=0.044)。结论：硅油填充后高眼压是角膜内皮细胞丢失的重要危险因素。

Objective: To evaluate the effect of intraocular pressure (IOP) on corneal endothelial cells after silicone oil tamponade. Methods: Patients (n=131) received vitrectomy with silicone oil injection in Ophthalmology Center in Second People’s Hospital of Foshan City from January 1st to September 30th 2019 were divided into the high IOP group (n=80) and normal IOP group (n=51). IOP was >21 mmHg at any time in the high IOP group and was ≤21mmHg in the normal IOP group after surgery. The values of corneal endothelial cells before filling with silicone oil and before removing silicone oil were compared.Results: The average IOP was 20.79 mmHg in the high IOP group, and 14.70 mmHg in the normal IOP group (P<0.001). The number of endothelial cells (ECD) was reduced, but the average endothelial cell area was increased (P<0.05) in both groups. The coefficient of variation of endothelial cell size in high IOP group was increased (P<0.05). ECD loss rate was 6.3% in the high IOP group and 3.5% in normal IOP group. Increased IOP within 1–6 weeks after surgery (7.1%) and IOP ≥40 mmHg (7.3%) had the greatest impact on ECD. ECD loss was correlated with IOP (r=0.176, P=0.044). Conclusion: High intraocular pressure after silicone oil filling is an important risk factor for the loss of corneal endothelial cells.Keywords intraocular pressure; corneal endothelium; silicone oil; vitrect

青光眼是世界范围内致盲和引起视力损害的主要眼病，也是不可逆性致盲性眼病之一。眼压是青光眼发生发展的重要危险因素，但除眼压外，血压在青光眼进展引起的影响也不可忽视。眼灌注压是血压和眼压的差值，可调节视神经的血液供应。眼压、血压、灌注压在青光眼发生发展中有一定相关性。本文通过对眼压和血压在青光眼中的影响以及24 h眼压和血压监测在青光眼中的应用进行文献索引，分析青光眼24h眼压和血压同步监测的意义。

Glaucoma is a major eye disease causing blindness and visual damage worldwide, and it is also one of the irreversible eye diseases causing blindness. Intraocular pressure (IOP) is an important risk factor for the development of glaucoma, and the influence of blood pressure (BP) on the progression of glaucoma also cannot be ignored. Eye perfusion pressure is the difference between blood pressure and intraocular pressure, regulating the blood supply to the optic nerves. IOP, BP and perfusion pressure are related to the occurrence and the progression of glaucoma. Literature review was performed related to the effects of IOP and BP on glaucoma, and the application of 24-hour IOP and BP monitoring in glaucoma, aiming to analyze the significance of simultaneous monitoring of IOP and BP for 24 hours.

目的：探讨全身麻醉诱导期应用不同种类的非去极化肌松药罗库溴铵、顺式阿曲库铵和米库氯铵对眼压升高的青光眼患者眼内压的影响。方法：将术侧眼眼压>21mmHg青光眼手术患者随机分配到罗库溴铵组、顺式阿曲库铵组和米库氯铵组。靶控输注丙泊酚至患者脑电双频指数(bispectral index，BIS)低于55后，根据组别分别静注0.6mg/kg罗库溴铵、0.1mg/kg顺式阿曲库铵及0.2mg/kg米库氯铵，待4个成串刺激(train of four stimulation，TOF)比值降至0后置入可弯曲喉罩，随后行机械通气并给予芬太尼1.5~2.0μg/kg，2%~3%七氟烷吸入维持麻醉。分别于麻醉诱导前(T0)、镇静后(T1)、肌松后(T2)及喉罩置入后(T3)测量三组青光眼患者术侧眼眼压并记录上述时间点血流动力学参数。结果：罗库溴铵组、顺式阿曲库铵组、米库氯铵组患者的眼压在T1、T2、T3时间点均较T0显著下降，差异有统计学意义(均P<0.001)；三组患者T2时间点眼压与T1相比差异均无统计学意义(P=0.337，P=0.520，P=0.062)；三组患者给予肌松药前后的眼压差值(T2–T1)分别为(0.68±4.39)、(0.36±3.72)和(1.27±3.91)mmHg，组间比较差异无统计学意义(P=0.353)。结论：非去极化肌松药罗库溴铵、顺式阿曲库铵及米库氯铵对眼压升高的青光眼患者的眼压无明显影响，且3种肌松药之间未见显著差异。

Objective: To compare the effects of different types of non-depolarizing muscle relaxants including rocuronium,cis-atracurium and mivacurium on intraocular pressure of glaucoma patients with elevated intraocular pressure during induction of general anesthesia. Methods: Glaucoma patients with intraocular pressure >21 mmHg were randomly assigned to rocuronium group, cis-atracurium group and mivacurium group. After target controlled infusion of propofol until the bispectral index (BIS) lower than 55, 0.6 mg/kg rocuronium, 0.1 mg/kg cisatracurium and 0.2 mg/kg mivacurium were injected intravenously according to different groups. The flexible laryngeal mask was placed after the train-of-four stimulation (TOF) ratio decreased to 0 and the mechanical ventilation was implemented immediately. General anesthesia was maintained by 1.5–2.0 μg/kg fentanyl and 2%– 3% sevoflurane. Intraocular pressure and hemodynamic parameters were measured before anesthesia induction (T0), after sedation (T1), after muscle relaxation (T2), and after laryngeal mask insertion (T3). Results: The intraocular pressure of patients in rocuronium group, cis-atracurium group and mivacurium group at T1, T2, T3 were lower than baseline (T0), and the difference was statistically significant (P<0.001); There was no significant difference in intraocular pressure at T2 compared with T1 in rocuronium group, cis-atracurium group and mivacurium group (P=0.337, P=0.520 and P=0.062 respectively); The difference of intraocular pressure between T2 and T1 in rocuronium group, cis-atracurium group and mivacurium group were (0.68±4.39), (0.36±3.72) and (1.27±3.91) mmHg respectively and there was no significant difference among the groups (P=0.353). Conclusion: The non-depolarizing muscle relaxants rocuronium, cis-atracurium and mivacurium have no significant effect on the intraocular pressure of glaucoma patients with elevated intraocular pressure, and there is no significant difference among the three muscle relaxants.
