目的：分析先天性葡萄膜外翻(Congenital ectropion uveae, CEU)继发性青光眼的临床表现、影像学特点和治疗方法。方法：回顾分析就诊于中山大学中山眼科中心诊断为CEU继发性青光眼患者的电子病历资料，收集整理患者的一般情况、视力、眼压、裂隙灯检查、房角镜照相、超声生物显微镜等检查结果，以及手术治疗方式选择和术后随访眼压情况，并结合国内外文献回顾分析总结CEU继发性青光眼的临床特点和诊疗效果。结果：报告两例CEU继发性青光眼患者年龄分别为24岁和11岁，均为男性、单眼发病慢性病程，患眼都为右眼，都不伴有全身异常，最佳矫正视力为手动/40cm-0.16，就诊时平均眼压为37 mmHg，平均中央前房深度为3.45 mm。两例患者查体表现：均角膜透明，瞳孔大小约5-5.5mm，对光反应灵敏，瞳孔缘近360°葡萄膜外翻呈棕褐色，晶状体透明，眼底检查青光眼性视杯凹陷，视网膜平伏。其中24岁患者房角镜检查全周宽角开放，小梁网有色素沉着。超声生物显微镜（ultrasound biomicroscopy, UBM）检查提示右眼虹膜稍向后凹，7点位房角关闭，其余全周房角开放。而11岁患者房角镜检查以及UBM检查均为全周房角关闭。两例患者角膜内皮镜检查均正常。两例患者均诊断为右眼先天性葡萄膜外翻继发性青光眼，眼压高，最大量降眼压药物治疗下不能控制，对24岁患者行小梁切除联合术中使用抗代谢药物、11岁患者行引流阀植入联合术中使用抗代谢药物，术中术后均无明显并发症，至今随访6个月，眼压控制良好。结论：CEU特征性改变为瞳孔缘葡萄膜外翻，常继发青光眼，可表现为开角型、房角发育异常（闭角型），降眼压药物治疗效果有限，通常需要手术治疗。由于CEU继发性青光眼人群以儿童和年轻患者为主，为难治性青光眼，因此抗青光眼术中联合使用抗代谢药物可获得较好的治疗效果。

Objective: To analyze the clinical manifestations, imaging characteristics, and treatment methods of secondary glaucoma associated with congenital ectropion uveae (CEU). Methods: Observational case series and literature review. A retrospective analysis was conducted on the electronic medical records of patients diagnosed with secondary glaucoma due to CEU at the Zhongshan Ophthalmic Center, Sun Yat-sen University, China. Data collected included demographics, visual acuity, intraocular pressure (IOP), slit-lamp examination, gonioscopy, ultrasound biomicroscopy (UBM), and surgical treatment methods. Postoperative IOP were also collected. A literature review was conducted to summarize the clinical characteristics and treatment outcomes of secondary glaucoma due to CEU. Results: Two male patients with secondary glaucoma due to CEU were included, aged 24 and 11 years, respectively. Both patients had a chronic course of disease affecting the right eye, with no systemic abnormalities. The best-corrected visual acuity was hand motion/40 cm to 0.16, and the average IOP at presentation was 37 mmHg, with an average central anterior chamber depth of 3.45 mm. Clinical examination revealed clear corneas, pupils measuring approximately 5-5.5 mm with brisk light reflexes, and nearly 360° of brownish ectropion of the uveae. The lenses were clear, and fundus examination showed glaucomatous optic disc cupping with a normal retina. In the 24-year-old patient, gonioscopy revealed a wide-open angle with trabecular meshwork pigmentation, while UBM indicated slight posterior bowing of the iris and angle closure at the 7 o'clock position. In the 11-year-old patient, both gonioscopy and UBM showed complete angle closure. Corneal endothelial microscopy was normal in both patients. Both were diagnosed with secondary glaucoma due to CEU in the right eye, with elevated IOP that was uncontrolled by maximal medications. The 24-year-old underwent trabeculectomy with intraoperative use of antimetabolites, while the 11-year-old received a drainage valve implantation with antimetabolites. No significant intraoperative or postoperative complications were observed, and IOP was well controlled over a six-month follow-up period. Conclusions: CEU is characterized by ectropion of the uveae and is frequently associated with secondary glaucoma, which may present as open-angle or angle-closure (goniodysgenesis) glaucoma. The effectiveness of IOP-lowering medications is limited, often necessitating surgical intervention. Given that secondary glaucoma due to CEU predominantly affects children and young adults, the use of antimetabolites during glaucoma surgery can yield favorable treatment outcomes.

先天性晶状体不全脱位是一种较为罕见的晶状体悬韧带异常的疾病，其手术治疗极具挑战性。以人工晶状体悬吊为代表的传统手术方式易出现囊袋破裂、玻璃体疝、人工晶状体脱位和继发性青光眼等严重并发症。近年来，以重建囊袋悬韧带隔为目标，新型囊袋辅助装置的应用极大程度提高了先天性晶状体不全脱位的手术成功率。然而，以改良式张力环为代表的囊袋辅助装置在我国仍难以得到普及且操作繁琐。因此，如何最大程度利用普通张力环等最常见的装备，设计出一种安全可靠手治疗先天性晶状体不全脱位的手术方式是眼科界亟待解决的问题。本文将介绍一种二期张力环缝合固定治疗先天性晶状体不全脱位手术技术。该技术仅需使用普通张力环，具有操作简单安全、术后效果稳定和易于技术推广的优点。

Congenital ectopia lentis is a relatively rare zonular disorder of the lens, and its surgical treatment is extremely challenging. The traditional surgical procedures represented by intraocular lens suspension are prone to result in serious complications such as capsular bag rupture, vitreous hernia, intraocular lens dislocation and secondary glaucoma. In recent years, with the goal of reconstructing the capsular bag–zonules diaphragm, the application of new capsular bag-assisted devices has greatly improved the surgical success rate of congenital ectopia lentis. However, the capsular-assisted devices, such as modified capsular tension ring, are still difficult to be popularized in China and the surgical procedures are complicated. Therefore, how to maximize the use of common equipment such as normal capsular tension rings and design a safe and reliable surgical method for the treatment of congenital ectopia lentis is an urgent issue for ophthalmologists. This article aims to introduce a two-stage capsular tension ring fixation for the treatment of congenital ectopia lentis, which has many advantages such as simple and safe operation, stable postoperative effect and less requirements for special equipment, and is worth promoting in clinical practice.

目的：通过对改良“Z”形无线结经巩膜缝线固定人工晶状体手术和传统有线结巩膜缝线固定人工晶状体手术治疗先天性晶状体脱位的比较来评价改良术式的临床疗效。方法：回顾性病例研究。纳入2018年1月—2021年3月期间于中山大学中山眼科中心行手术治疗的先天性晶状体脱位患者73例73眼，按手术方式不同将患者分为无线结组36例36眼和有线结组37例37眼。比较两组患者术前和术后1年的球镜度(DS)、柱镜度(DC)、等效球镜(SE)、最佳矫正视力(BCVA)、眼压(IOP)、眼轴长度(AL)、角膜内皮细胞计数和术后并发症的发生率。结果：两组患者术前各项观察指标组间比较差异无统计学意义(均P>0.05)。两组患者术后1年 BCVA 均较术前提高(均P<0.05)，SE均较术前降低(均P<0.05)。两组患者术后1年 BCVA 、DS、DC、SE、IOP、AL、角膜内皮细胞丢失率组间比较差异均无统计学意义(均P>0.05)。术后1年，有线结组有5例(13.5%)出现缝线暴露，无线结组未出现缝线暴露，组间比较差异有统计学意义(P<0.05)。结论：改良无线结 IOL 巩膜缝线固定手术可改善CEL患者的最佳矫正视力和屈光不正，有效减少缝线暴露及相关并发症。

Objective: To evaluate the clinical efficacy of modified “Z”-shaped knotless transscleral suture fixation intraocular lens (IOL) and traditional knotted transscleral suture fixation IOL in congenital ectopia lentis. Methods: A retrospective case study. A total of 73 eyes of 73 patients with congenital ectopia lentis who underwent surgical treatment in our hospital from January 2018 to March 2021 were included. According to different surgical methods, the patients were divided into the knotless group (36 eyes) and knotted group (37 eyes). Preoperative and postoperative of 1-year diopter sphere (DS), diopter cylinder (DC), spherical equivalent (SE), best corrected visual acuity (BCVA), intraocular pressure (IOP), and axial length (AL), corneal endothelial cell counts and the occurrence of postoperative complications rate were analyzed among two groups. Results: There was no significant difference in preoperative outcome measures between the two groups (P>0.05). BCVA at 1-year postoperative was significantly better (P<0.05), and SE at 1-year postoperative was significantly lower (P<0.05). There was no significant difference in BCVA, DS, DC, SE, IOP, AL, and corneal endothelial cell loss rate between the two groups at 1-year after operation (P>0.05). One year after the operation, there were 5 cases of suture exposure (13.5%) in the knotted group and no suture exposure in the knotless group, and the difference was statistically significant (P<0.05). Conclusions: The modified knotless IOL transscleral suture fixation can improve the best corrected visual acuity and alleviate ametropia of CEL patients, and reduce suture exposure and related complications effectively.

先天性晶状体脱位(congenital ectopia lentis, CEL)是一种罕见的遗传相关性疾病，其主要临床特征是晶状体悬韧带先天性发育异常，导致晶状体偏离正常解剖位置。随着病情的进展，CEL可引起高度屈光不正甚至弱视外，还可能导致继发性青光眼和视网膜脱离等严重的并发症。目前，手术仍是改善CEL患儿视觉质量及防治并发症的主要手段。常用的手术方式包括晶状体摘除术、前房型人工晶状体(intraocular lens, IOL)植入术、囊袋支撑装置联合IOL植入术及经巩膜IOL固定术等，这些手术方式各具特点，但目前最佳手术方式仍未有定论。既往大量文献表明，手术能够显著改善CEL患儿视力，但随着眼球的生长发育，CEL患儿术后屈光状态常出现近视漂移。此外，术后并发症如缝线暴露，IOL瞳孔夹持、IOL脱位、视网膜脱离等仍有可能发生，需要长期的严密随访。这些因素都使得CEL的治疗具有挑战性。为此，文章就CEL的手术方式、视力预后、术后屈光变化及术后并发症进行综述，旨在为该疾病的临床诊断及治疗提供更为全面和深入的理解。

Congenital ectopia lentis (CEL) is a rare genetic disorder characterized by the displacement of the lens from its normal anatomical position due to abnormalities in the lens zonular. As the progression of the disease, CEL can lead to high refractive error, even amblyopia, as well as other serious complications such as secondary glaucoma and retinal detachment. Currently, surgical intervention remains the primary method to improve the visual quality and prevent complications in children with CEL.Common surgical options include lens extraction, anterior chamber intraocular lens (IOL) implantation, IOL implantation combined with capsular tension devices, and transcleral fixation of IOL. Each surgical approach has its own characteristics, but there is currently no consensus on the best surgical method. Previous literature has shown that surgery can significantly improve vision in children with CEL; however, due to the growth of the eye, postoperative refractive status often experiences myopic shift. Additionally, complications such as suture exposure, IOL pupil capture, IOL dislocation, and retinal detachment may still occur, necessitating long-term close follow-up. These factors make the treatment of CEL challenging. This article reviews the surgical approaches, visual prognosis, postoperative refractive changes, and postoperative complications associated with CEL, aiming to provide a more comprehensive and in-depth understanding for the clinical diagnosis and treatment of this disease.

Background: To investigate the 1-time success rate of probing alone and nasolacrimal duct probing combined with nasolacrimal injection of levofloxacin ophthalmic gel on congenital nasolacrimal duct obstruction (CNLDO) in young children.

Methods: A retrospective case series was performed on 494 cases (647 eyes) of 3–12 month-old children with CNLDO between July 2014 and July 2015. Material obtained from the lacrimal sac was cultured to isolate infectious agents. Susceptibility testing was done. Children from 3–12 months of age who were found to be sensitive to Levofloxacin (n=493 eyes) were separated into two groups: 3–6 months of age (276 eyes) and 7–12 months of age (217 eyes). Each of the groups were then randomized into group A (138 eyes of 3–6 months of age; 102 eyes of 7–12 months of age) and group B (138 eyes of 3–6 months of age; 115 eyes of 7–12 months of age). Children in group A underwent nasolacrimal duct probing alone; those in group B underwent nasolacrimal duct probing plus nasolacrimal duct injection of levofloxacin and the efficacy of probing was evaluated.

Results: The average detection rate of pathogenic bacteria in dacryocystitis was 75.1%, and Staphylococcus aureus was found to be the main pathogenic bacteria (42.59%, 106 cases). Among children from 7–12 months of age, the 1-time success rate of nasolacrimal duct probing alone was 88.24% and the 1-time success rate of probing combined with nasolacrimal duct injection of levofloxacin ophthalmic gel was 96.52% (statistical significance, P=0.02<0.05).

Conclusions: Most pathogenic bacteria (96.81%) were sensitive to levofloxacin. Nasolacrimal duct probing combined with nasolacrimal duct injection of levofloxacin may improve the success rate of probing in children older than 6 months of age.

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状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。

      封面展示的是双眼先天性白内障术后继发青光眼(左眼)与正常眼(右眼)的对比示意图。该并发症起病隐匿、难以预测，是先天性白内障术后二次致盲的首要原因。针对这一术后并发症，美国婴儿无晶状体眼治疗研究组 (infant aphakia treatment study, IATS)将儿童白内障术后青光眼相关不良事件(glaucoma-related adverse events,GRAEs，包括了青光眼和可疑青光眼)定义为：1)青光眼：眼压>21 mmHg(1 mmHg=0.133 kPa)，且有以下一种或以上的解剖学改变：(a)角膜直径增加；(b)双眼不对称进行性近视漂移伴角膜直径和(或)眼轴的增加；(c)视杯直径进行性增大，杯盘比增加≥0.2；(d)必须进行手术才能控制眼压。2)可疑青光眼：停用局部糖皮质激素(激素)后连续2次眼压>21 mmHg，或可通过抗青光眼药物控制眼压，但无上述任何青光眼的解剖改变。所以，如何更精准地预防该术后并发症，防止对患儿视功能造成进一步的损害，是目前关键的临床问题。

       因此，文章对先天性白内障摘除及人工晶状体植入术后继发性青光眼和可疑青光眼的发生、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，减少术后并发症对患儿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.

该文报道一例30岁的男性患者因“双眼自幼视力不佳，强光下视物模糊加重4年余”就诊，经过眼部检查评估，诊断为双眼瞳孔残膜、双眼屈光不正。患者接受一期双眼瞳孔残膜切除、二期双眼行有晶状体眼后房型环曲面人工晶状体(toric implantable collamer lens,TICL)植入手术，术后视力恢复良好。文章回顾了该例患者的诊治过程，为临床屈光不正同时伴有瞳孔残膜患者的诊治提供参考。

A 30-year-old male patient presented at our institution with a history of poor vision in both eyes since childhood, exacerbated by blurriness under bright light for over four years. Following a comprehensive ophthalmic examination, the patient was diagnosed with bilateral pupillary membrane remnants and refractive errors. The patient underwent a two-stage surgical intervention, starting with the removal of the pupillary membrane remnants, followed by the implantation of toric implantable collamer lenses (TICL) in the posterior chamber of the lensless eyes. Postoperative outcomes were favorable, with significant improvement in visual acuity. This article reviews the therapeutic journey of the patient, offering insights into the diagnosis and management of individuals with concurrent refractive anomalies and pupillary membrane remnants, thereby contributing to the clinical discourse on the subject.

上睑下垂是眼整形科最常见的疾病之一，由于儿童处于生长发育阶段的特殊性，不规范的诊疗不仅会影响外观，同时可能会导致视功能发育迟缓。目前关于儿童先天性上睑下垂的手术时机和手术方式的选择尚无统一的标准和共识，本文通过对儿童先天性上睑下垂分类细化，阐明合并不同原因导致弱视的患者手术时机的选择；对比不同手术方式，分析其原理及优缺点，进一步明确矫正重度儿童先天性上睑下垂的手术方式，以期规范儿童先天性上睑下垂手术时机和手术方式的选择，提高手术的成功率，减少弱视的发生。

Blepharoptosis is one of the most common diseases in oculoplastics. Due to the particularity of children in the stage of growth and development, non-standard diagnosis and treatment not only affect the appearance,but also lead to the retardation of visual function development. Currently, there are no uniform standards and consensus on the choice of surgical timing and methods for pediatric congenital blepharoptosis. Here through refined classification of congenital blepharoptosis, we try to elucidate the choice of surgical timing for congenital blepharoptosis patients combined with amblyopia caused by a variety of reasons. By comparing different surgical methods, we analyze their mechanisms and advantages, and illustrate the surgical indication for severe congenital blepharoptosis, so as to standardize the choice of surgical timing and methods for pediatric congenital ptosis,improve the surgical success rate, and reduce the occurrence of amblyopia.
