儿童白内障是全球范围内可治疗儿童盲症的主要原因之一。对于这些患儿而言，手术是恢复或保护视力的主要方法。然而，手术后的并发症，特别是青光眼相关不良事件(glaucoma-related adverse events, GRAEs)，常常成为导致儿童二次致盲的主要原因，这引起了眼科医疗领域的广泛关注。文章综述了儿童Ⅱ期人工晶状体植入术后GRAEs的影响因素，包括手术设计、眼部解剖特征、其他眼部发育异常和全身疾病等。手术设计中是否植入人工晶状体(intraocular lens，IOL)以及植入的时机和位置都对GRAEs的发生有显著影响。此外，眼部解剖特征如角膜直径、眼轴长度、前房深度、中央角膜厚度和术前晶状体厚度等，也是影响GRAEs发生的重要因素。同时，其他眼部发育异常和全身疾病，如先天性无虹膜、先天性风疹综合征等，也会增加儿童白内障术后青光眼的发生率。文章还总结了预测GRAEs的方法，并推荐使用Cox回归模型建立预测模型。这种模型可以有效地预测儿童Ⅱ期IOL植入术后在特定时间段内发展为GRAEs的概率，从而为早期识别GRAEs高危儿童提供了重要的借鉴。通过对GRAEs影响因素的深入分析和预测模型的建立，文章旨在帮助眼科医生更好地理解GRAEs的发生机制，并在手术前对患儿进行风险评估，从而选择最佳的手术方案和预防措施。这对于改善患儿的术后恢复、减少并发症、保护视功能具有重要的临床意义。

Pediatric cataract is one of the leading causes of treatable childhood blindness worldwide. For these children, surgery is the primary method to restore or preserve vision. However, postoperative complications, particularly glaucoma-related adverse events (GRAEs), often become the main reason for secondary blindness in children, attracting widespread concern in the field of ophthalmology. This study reviews the impact factors of glaucoma-related adverse events after secondary intraocular lens (IOL) implantation in children, including surgical design, ocular anatomical characteristics, other ocular developmental abnormalities, and systemic diseases. Whether to implant an IOL in the surgical design and the timing and positioning of the implantation have a significant impact on the occurrence of GRAEs. In addition, ocular anatomical characteristics, such as corneal diameter, axial length, anterior chamber depth, central corneal thickness, and preoperative lens thickness, are also important factors affecting the occurrence of GRAEs. At the same time, other ocular developmental abnormalities and systemic diseases, such as congenital aniridia and congenital rubella syndrome, also increase the incidence of glaucoma after pediatric cataract surgery. The article also summarizes methods for predicting GRAEs and recommends using the Cox regression model to establish a predictive model. This model can effectively predict the probability of children developing GRAEs after secondary IOL implantation within a specific time period, providing an important reference for the early identification of high-risk children for GRAEs. Through in-depth analysis of the impact factors of GRAEs and the establishment of predictive models, the article aims to help ophthalmologists better understand the mechanisms of GRAEs and assess the risks of children before surgery, thereby selecting the best surgical plan and preventive measures. This is of great clinical significance for improving postoperative recovery in children, reducing complications, and protecting visual function.

高度近视(high myopia，HM)作为一种特殊类型的屈光型眼病，不仅会导致进行性、退行性眼底改变，其视神经损伤的患病率也很高。青光眼是全球范围内最常见的一种不可逆致盲性眼病，原发性开角型青光眼(primary open-angle glaucoma，POAG)是最常见的青光眼类型。近年来的研究发现HM与POAG的病理改变存在相似之处。由于HM眼底改变与早期POAG眼底改变容易混淆，HM患者早期发现POAG对延缓或阻止疾病进展很重要。HM患者长期随访不仅要观察黄斑病变，视神经形态与结构改变的观察也不容忽视。

As a special type of refractive eye disease, high myopia (HM) not only causes progressive and degenerative fundus changes, but also has a high prevalence of optic nerve damage. Glaucoma is the most common form of irreversible blinding eye diseases worldwide, among which, primary open-angle glaucoma (POAG) is the most common type. In recent studies, HM is found to have similarities on pathological changes as that of POAG. And HM fundus changes are easily confused with early stage POAG fundus changes; thus, the early detection of POAG on HM patients is highly important on disease deferment or prevention of disease progression. Macular degeneration as well as optic nerve morphology and structural changes are to be observed in the long-term follow-up for HM patients.

房角镜辅助的内路360°小梁切开术(Gonioscopy-Assisted Transluminal Trabeculotomy,GATT)是近年来国内外开展的新型微创青光眼手术，是一种改良的小梁切开术。GATT将微导管(iTrack)环穿Schlemm's管后，利用微导管张力全周切开小梁网及Schlemm's管内壁，重建生理性房水流出通道，避免小梁网阻力，实现房水从前房直接进入集液管，通过增加房水流出机制降低眼压。GATT适应证广泛，主要应用于开角型青光眼，包括原发型开角型青光眼和继发性开角型青光眼，同时可运用于闭角型青光眼。GATT微创、不依赖滤过泡、能明显减少降眼压药物的使用、中远期疗效稳定、安全性高、较少发生威胁视力的并发症，可作为开角型青光眼的首选手术方式。本文将对GATT在青光眼中的应用、手术步骤、作用机制、有效性、并发症及影响疗效的因素等进行综述，以期为其临床运用提供参考。

As a modifed trabeculotomy, Gonioscopy-Assisted Transluminal Trabeculotomy (GAT) is a new type of minimally invasive glaucoma surgery developed at home and abroad in recent years. GAT inserts a microcatheter (iTrack) into the Schlemm's canal and advance the catheter through the canal circumferentially 360°, then circumferentially fracture the trabecular meshwork and inner wall of Schlemm’s canal. Tis method can reduce intraocular pressure by increasing the outfow of aqueous humor. Te physiological outfow pathway of aqueous humor is reconstructed, which can avoid the resistance of trabecular meshwork and realizing the direct entry of the aqueous humor directly into the collector channel from the anterior chamber. With a wide range of indications, GAT is mainly used in open-angle glaucoma, including primary open-angle glaucoma and secondary open-angle glaucoma, and is also used in primary closed- angle glaucoma. Additionally, GATT can be the preferred surgical modality for open-angle glaucoma, as it has the following advantages: minimally invasive, independent of fltration bleb, can signifcantly reduce the use of medications, stable medium- and long-term efcacy, high safety, and has fewer sight-threatening complications. In order to provide a reference for clinical application, this article reviews the indications, mechanism of action, surgical procedures, efectiveness, complication and factors afecting therapeutic efect.

Schlemm管(Schlemm’ s canal, SC)作为房水流出的主要通道，通过调节房水外排来维持眼内压的平衡，其结构和功能的异常与高眼压及青光眼的发生发展密切相关。对SC的研究有助于阐明房水外排阻滞的发生机制、探索促进房水外排新的途径，从而为降低眼压和青光眼治疗的新药物开发提供理论基础。目前，对SC发育和功能的调节机制的认识仍然有限，缺乏针对SC的特异性治疗策略。近年来，关于SC细胞命运决定及其结构发育的细胞学机制逐渐被揭示，功能调控的关键分子靶标也相继被发现，这促进了对SC结构和功能调控的深入理解。此外，作为降眼压药物靶点和针对性手术的创新应用也在不断拓展。文章系统回顾SC的结构与功能研究，总结关键的分子和细胞学调控机制，归纳SC相关药物和手术疗法的最新进展，为青光眼的临床诊治提供了新的思路。

Methods: Selected 46 cases (50 eyes) of patients with PACG, including 26 cases (27 eyes) of acute angle closure glaucoma at the preclinical stage and remission phase of ocular and 20 cases (23 eyes) of chronic angle closure glaucoma, implemented LPI, examined the anterior chamber angle opening distance at the point of 500 and 750 μm from posterior to the scleral before and after surgery for 2 weeks by OCT, using a paired t-test. Results: Compared the anterior chamber angle opening distance before and after surgery for 2 weeks, the difference in patients with acute angle closure glaucoma was statistically significant (P<0.05), but not statistically significant in patients with chronic angle closure glaucoma (P>0.05). Conclusion: The opening distance of the anterior chamber angle of the patients with acute angle  closure glaucoma after LPI was increased, and the treatment effect was better; but of the patients with chronic angle closure glaucoma after LPI, the distance was not obviously increased, the tendency of anterior chamber angle occlusion still existed after LPI.

      青光眼(glaucoma)是一组具有特征性视神经损害和视野缺损的眼病,在临床上常常表现为视力减退、眼部胀痛伴头痛等症状，是一种致盲率居第二位的不可逆性眼病。青光眼视神经损伤有一定 的遗传倾向，造成视神经凹陷性萎缩及视野不同程度缺损这两种结局的危险因素有多种,其中致盲的主要原因包括进行性视神经节损害、病理性眼压升高等。所以在青光眼的治疗中一方面要考虑降低眼压，另一方面还要保护好视神经。本文将从视神经损害的机制、影响因素、分级方法、视神经相关检测指标及其在临床上相关仪器应用、治疗等方面进行综述。

Glaucoma is an irreversible eye disease with the characteristic of optic nerve damage and visual ?eld defect, the clinical manifestation is behaved for vision loss, eye pain with symptoms such as headache, which rate of blindness ranks second place. The optic nerve injury of glaucoma has a certain genetic predisposition. There are many risk factors result in optic nerve atrophy and visual ?eld defect, one of the major causes of blindness including optic ganglion damage, pathological elevation of intraocular pressure. So on the one hand in the treatment of glaucoma should be considered to reduce intraocular pressure, on the other hand, to protect the optic nerve. This article will reviews the mechanism, influencing factors, classification methods, optic nerve related detection indexes and clinical application and treatment of optic nerve injury. 

青光眼是一组以病理性眼压升高为主要危险因素的，以青光眼性神经萎缩和视野缺损为主要特征的全球首位不可逆性致盲眼病。超声睫状体成形术(UCP)是一种新型非侵入性青光眼治疗技术，其降眼压主要原理为利用高强度聚焦超声破坏睫状突上皮细胞以减少房水生成，并增加葡萄膜巩膜通道的房水流出。UCP适应证广泛，早期主要用于各类难治性青光眼患者，特别是晚期及绝对期患者，研究者发现其除降眼压外，还能够显著缓解该类患者的局部疼痛。近年来，UCP在未经手术治疗的青光眼患者和早、中期青光眼病例中，也表现出了良好的降眼压效果，同时显示出较少的并发症和较轻的术后反应，并可重复治疗。然而不同类型青光眼UCP疗效存在一定差异，且为达最佳治疗效果，其治疗需匹配恰当的探头型号以及适当的治疗扇区。现有较广泛应用于国外的基于眼轴和白到白参数的公式计算方法，测算精度并不适用于国人，然而精准度更高的模型法，其便捷性仍有待进一步提高。UCP虽可减少降眼压药物用量，但术后用药策略的调整仍可能导致眼压波动。综上，针对UCP手术的适应证选择、手术参数设计、疗效预判以及术后管理策略等，仍有待开展相关临床研究，以期为其临床应用提供更加可靠的依据。
