    Artificial intelligence (AI) has been proposed as a potential solution to address the shortage of ophthalmologists in China. With the increasingly extensive application of AI in the field of ophthalmology, many potential patients with eye diseases have access to a higher quality of medical services. At the same time, new challenges will emerge and proliferate with the advancement of AI application. This paper focuses on the patient handoffs process and discusses two challenges brought by the application of AI, namely “communication” and “standardization”. Natural language processing techniques and the development of standardized databases are proposed to solve each of these challenges. The application prospects of AI in ophthalmology are eventually discussed.

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.

人工智能是对人类智能的模拟和拓展。基于深度学习的人工智能可以很好地利用图像的内在特征，如轮廓、框架等，来分析图像。研究人员通常利用图像来诊断眼底病，因此将人工智能应用于眼底检查是有意义的。在眼科领域，人工智能通过分析光学相干断层扫描图像、眼底照片和超宽视野图像，已经在检测多种眼底疾病上取得了类似医生的性能。它也已经被广泛应用于疾病进展预测。然而，人工智能在眼科的应用也存在一些潜在的挑战，黑盒问题是其中之一。研究人员致力于开发更多的可解释的深度学习系统，并确认其临床可行性。人工智能在最流行的眼底病中的最新应用、可能遇到的挑战以及未来的道路将一一阐述。

Artificial intelligence (AI) is about simulating and expanding human intelligence. AI based on deep learning (DL) can analyze images well by using their inherent features, such as outlines, frames and so on. As researchers generally diagnoses ocular fundus diseases by images, it makes sense to apply AI to fundus examination. In ophthalmology, AI has achieved doctor-like performance in detecting multiple ocular fundus diseases through optical coherence tomography (OCT) images, fundus photographs, and ultra-wide-field (UWF) images. It has also been widely used in disease progression prediction. Nonetheless, there are also some potential challenges with AI application in ophthalmology, one of which is the black-box problem. Researchers are devoted to developing more interpretable deep learning systems (DLS) and confirming their clinical feasibility. This review describes a summary of the state-of-the-art AI application in the most popular ocular fundus diseases, potential challenges and the path forward.

蜡样芽孢杆菌性眼内炎（Bacillus cereus endophthalmitis）是由蜡样芽孢杆菌经外源性/内源性途径感染引发的严重眼部疾病，以暴发性进展、预后不良为特征。典型临床表现为眼组织咖啡样溶解、前房咖啡色积脓及视网膜不可逆损伤，即使采用万古霉素抗感染联合玻璃体手术治疗，仍有75%～91%的患者难以恢复有效视力，约30%的患者因眼球内容物剜除或眼球摘除而致残。当前临床诊疗仍面临双重瓶颈：其一，蜡样芽孢杆菌致病机制复杂，核心因素尚未明确；其二，玻璃体切割术联合万古霉素治疗虽可延缓病程，但多数患者预后仍较差，诊疗策略有待优化。本文系统综述蜡样芽孢杆菌性眼内炎分子致病机制研究进展，基于溶细胞毒素[溶血素BL（hemolysin BL, HBL）/非溶血性肠毒素（non-hemolytic enterotoxin, NHE）/细胞毒素K（cytotoxin K, CytK）/溶血素(hemolysin）]的膜破坏作用和炎症反应、磷脂酶类的侵袭性与超氧化物歧化酶的免疫逃逸、菌体结构组分（鞭毛、菌毛、S层蛋白）致病效应以及宿主免疫应答[Toll样受体（Toll-like receptor, TLR）/NLRP3炎症小体（NLRP3 inflammasome）]失衡四个方面，整合分析国内外基础研究数据，以期为该病致病机制深度解析、靶向治疗策略探讨和转化医学前景展望等提供理论框架。

Bacillus cereus endophthalmitis is a severe ocular infection characterized by rapid progression and a poor prognosis, which can originate from either exogenous or endogenous sources. Clinically, it manifests as coffee-colored hemorrhages in ocular tissues, coffee-colored hypopyon in the anterior chamber, and irreversible retinal damage. Despite the implementation of infection control measures, such as vancomycin treatment and vitrectomy, 75%–91% of patients are unable to regain functional vision. Moreover, approximately 30% of patients require enucleation or removal of ocular contents, resulting in significant disability. The current clinical diagnosis and treatment of Bacillus cereus infections are confronted with two major challenges. Firstly, the pathogenic mechanisms are complex, and key contributing factors remain unidentified. Secondly, although vitrectomy combined with vancomycin can slow down the progression of the disease, the prognosis for most patients remains dismal, highlighting the urgent need for improved diagnostic and treatment strategies. This review conducts a systematic examination of the molecular pathogenic mechanisms of B. cereus endophthalmitis, integrating findings from both domestic and international studies. Specifically, this paper offers a comprehensive and systematic review of the latest research on the molecular pathogenic mechanisms of Bacillus cereus endophthalmitis, with a focus on four main areas: the membrane-damaging effects and inflammatory responses induced by cytolytic toxins (HBL/NHE/CytK/hemolysin); the invasiveness of phospholipases and immune evasion by superoxide dismutase; the pathogenic effects of bacterial structural components (flagella, pili, S-layer proteins);  the imbalance in host immune responses (TLR receptors/NLRP3 inflammasome). By integrating and analyzing research data from both domestic and international, this review aims to establish a theoretical framework. This framework is intended to enhance in-depth understanding of the disease’s pathogenic mechanisms, facilitate the exploration of targeted therapeutic strategies, and offer insights into the future prospects of translational medicine.

目的：干眼已成为影响儿童和青少年眼健康的重要问题，但其流行病学特征及相关因素尚未在中国西部地区儿童和青少年群体中得到充分研究。本研究旨在调查新疆喀什地区英吉沙县学龄儿童和青少年的干眼患病率，并分析其相关因素，为儿童和青少年干眼的防治提供流行病学依据。方法：本研究为横断面研究，于2024年5—6月在英吉沙县第三中学和芒辛镇中心小学开展，共纳入3 305名在校儿童和青少年进行问卷调查，并随机抽取557名儿童和青少年进行眼表检查。采用眼表综合分析仪测量泪河高度和非接触泪膜破裂时间。干眼诊断基于世界泪膜与眼表学会发布的第二版干眼专家共识（2017）。采用多因素logistic回归分析干眼的相关因素。结果：在557名参与儿童和青少年中，干眼患病率为16.88%（94/557）。不同性别间干眼患病率比较差异无统计学意义（P=0.81）。干眼患病率随年龄增长而增加，具有显著的线性趋势。任一眼有屈光不正的儿童和青少年干眼患病率更高（29.05% vs. 12.47%，P<0.001）。多因素Logistic回归分析显示年龄（OR=1.21）和屈光不正（OR=2.72）是干眼的危险因素，性别、身体质量指数、右眼眼轴长度及父母近视情况无关。结论：新疆喀什地区英吉沙县学龄儿童和青少年的干眼患病率与全国均值相近且偏低，年龄增长和屈光不正显著增加干眼患病风险，应关注儿童和青少年屈光状态对眼表健康的影响，并采取相应的预防措施。

Objective: Dry eye (DED) has emerged as an important ocular health concern among children and adolescents. However, in pediatric populations in western China, its epidemiological characteristics and associated risk factors have not been thoroughly investigated. This study aimed to investigate the prevalence of DED and analyze its risk factors among school-age children and adolescents in Yingjisha County, Kashi, Xinjiang, so as to provide a solid evidence base for formulating prevention and control strategies. Methods: This cross-sectional study was conducted from May to June 2024 at Yingjisha County No. 3 Middle School and Mangxin Central Primary School. A total of 3,305 school children and adolescents completed the questionnaire, and 557 of them were randomly selected for ocular surface examinations. The Keratograph 5M was used to measure tear meniscus height (TMH) and non-invasive tear break-up time (NIBUT). DED diagnosis adhered to the Dry Eye WorkShop II 2017 (DEWS II) criteria published by Tear Film & Ocular Surface Society (TFOS). Multivariate logistic regression was applied to evaluate the associated risk factors. Results: Among the 557 children and adolescents who underwent examinations, the prevalence of DED was 16.88% (94/557). No statistically significant difference was observed between genders (P = 0.81). The prevalence of DED increased with age, showing a significant linear trend. Participants with refractive errors in either eye had a significantly higher prevalence of DED (29.05% vs. 12.47%, P< 0.001). Logistic regression analysis identified age (OR = 1.21) and refractive error (OR = 2.72) as risk factors. No significant associations were found for gender, Body Mass Index (BMI), axial length of the right eye, or parental myopia. Conclusions: The prevalence of DED among school-age children and adolescents in Yingjisha County is either comparable to or slightly lower than, the national average. Age and refractive error substantially increase the risk of DED. Greater attention should be directed towards children’s refractive status to protect ocular surface health and implement early preventive measures.

目的：调查神经眼科用药现状，并对其超说明书用药进行评价，探索科学有效的管理策略，为神经眼科的临床合理用药提供参考。方法：随机抽取2023年7—12月郑州市第二人民医院神经眼科处方，依据国家药品监督管理局核准的药品说明书、美国食品药品监督管理局(Food and Drug Administration, FDA)说明书及PubMed、Micromedex等循证医学数据库证据判断超说明书用药类型，并对其进行分类(包括超适应证、超剂量、超疗程、超给药途径等)。同时基于Thomson分级理论建立三级评价标准，分别为A级(高证据等级，仅需口头告知)，B级(中证据等级，需在病历或病程中详细记录)，C级(低证据等级，须患者签署书面知情同意书)。通过处方前置审核系统干预，对未纳入评价标准的超说明书用药进行实时拦截与分级警示，比较2023年下半年(干预前)与2024年下半年(干预后)超说明书用药处方的不合理率变化。 结果：干预前共抽取超说明书处方370张，超说明书类型主要为超适应证、超给药途径和超剂量及次。干预后，共抽取超说明书用药560张，超说明书用药不合理率从9.2%(34/370)降至2.9%(16/560)。结论：神经眼科超说明书用药普遍，主要源于视神经炎、缺血性视神经病变等复杂疾病的治疗需求与药品审批滞后之间的矛盾。基于循证医学证据构建分级管理体系，结合信息化实时干预，可有效规范超说明书用药行为，降低医疗风险。

Objective: To investigate the current status of medication use in neuro-ophthalmology, evaluate off-label drug use, and explore scientific and effective management strategies, providing references for rational drug use in neuro-ophthalmology clinical practice. Methods: We Randomly selected neuro-ophthalmology prescriptions from July to December 2023 in our hospital. By refering to the drug instructions approved by the National Medical Products Administration, FDA instructions, and evidence from evidence-based medical databases such as PubMed and Micromedex, we identified and classified the types of off-label drug use, including off-label indications, off-label doses, off-label courses, off-label administration routes, among others. Simultaneously, based on the Thomson classification theory, we established a threelevel evaluation standard: Level A (high evidence level, requiring only oral notification); Level B (medium evidence level, necessitating detailed records in the medical record or medical course); Level C (low evidence level, demanding patients sign a written informed consent form). Through the intervention of pre-prescription review system, we carried out real-time interception and classification warnings for off-label drug use not covered in the evaluation standards. We then compared the changes in the unreasonable rate of off-label drug use prescriptions from the second half of 2023 (before intervention) to the second half of 2024 (after intervention). Results: Before the intervention, a total of 1852 prescriptions were selected, with the proportion of off-label drug use at 19.98% (370 prescriptions), primarily involving off-label indications (90.27%). After the intervention, the unreasonable rate of off-label drug use decreased from 9.2% (34/370) to 2.9% (16/560). Conclusions: Off-label drug use is prevalent in neuro-ophthalmology, mainly due to the conflict between the treatment requirements for complex diseases such as optic neuritis and ischemic optic neuropathy and the delay in drug approval. By constructing a hierarchical management system based on evidence-based medical evidence and combing it with real-time information-based intervention, we can effectively regulate off-label drug use behavior and reduce medical risks.

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、探索新的途径以增加房水排出，从而为降低眼压和青光眼治疗的新药物开发提供基础。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靶向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。

Schlemm's canal (SC), as the primary pathway for aqueous humor drainage, maintains intraocular pressure balance by regulating aqueous outflow. Abnormalities in its structure and function are closely associated with elevated intraocular pressure and the development of glaucoma. Research on SC aids in elucidating the mechanisms behind outflow resistance and exploring new avenues to enhance aqueous drainage, thereby providing a foundation for the development of new drugs aimed at lowering intraocular pressure and treating glaucoma. Currently, our understanding of the mechanisms regulating SC development and functionality remains limited, with a lack of specific therapeutic strategies targeting SC. In recent years, advancements in measurement and imaging technologies have revealed the molecular and cellular mechanisms underlying SC development, leading to the identification of key regulatory targets. This has enhanced our understanding of SC structural and functional regulation. Furthermore, innovative applications of SC as a target for intraocular pressure-lowering medications and surgical interventions are continually expanding. This article systematically reviews the research on the structure and function of SC, summarizes the key molecular and cellular regulatory mechanisms, and discusses the latest advancements in SC-targeted pharmacological and surgical therapies, providing new insights for the clinical diagnosis and management of glaucoma.

Objective: To explore holistic nursing strategies to improve the quality and efficiency of post-anesthesia care unit (PACU) resuscitation in childrenpatients undergoing ophthalmic laryngeal mask anesthesia. Methods: A total of 24,180 children patients who underwent general anesthesia and retained laryngeal mask airway for PACU resuscitation at Sun Yat-sen Ophthalmic Center of Sun Yat sen University from January 2020 to December 2023 was reviewed and summarized the nursing measures and resuscitation quality of children patients undergoing PACU resuscitation. Results: All patients underwent comprehensive care during the recovery period and successfully removed the laryngeal mask to complete anesthesia recovery. There were no cases of secondary intubation or unplanned transfer for treatment during the recovery period. After adopting personalized holistic nursing strategies, the average recovery time of PACU in children under laryngeal mask anesthesia was significantly shortened.The incidence of common postoperative complications(postoperative agitation, hypoxemia and respiratory obstruction)and adverse nursing events (indwelling needle falls off, eye bandage fall off)had been decreasing year by year. These complications had been improved after treatment and care. Conclusions: Based on the characteristics of children patients undergoing general anesthesia in ophthalmology, adopting personalized holistic nursing strategies during the anesthesia recovery period is beneficial for successfully completing anesthesia recovery, reducing the incidence of anesthesia complications and adverse nursing events, improving the quality and efficiency of recovery, and meeting the needs of rapid recovery in ophthalmic day surgery.

目的：探究间歇性禁食(intermittent fasting, IF)对内毒素诱导小鼠葡萄膜炎(endotoxin-induced uveitis, EIU)的保护作用及其可能的抗炎机制。方法：小鼠随机分为对照组、EIU组及IF+EIU组。16∶8禁食方案(9 : 00—17 : 00进食)。对照组行玻璃体腔内注射磷酸盐缓冲溶液(phosphate buffered saline, PBS)，其余两组行玻璃体腔内脂多糖注射。建模后监测小鼠空腹血糖及体质量。光学相干断层扫描和苏木精伊红染色观察评估炎症水平。视网膜铺片行神经炎症相关的观察评价。BV2细胞分为Ctr组，LPS组及饥饿+内毒素组，蛋白印迹及实时荧光定量逆转录PCR技术检测相关蛋白及mRNA表达水平。结果：①IF对体质量无明显影响，可引起血糖显著降低随后逐渐恢复。病程中期起IF干预下小鼠视网膜水肿恢复，玻璃体腔内炎性渗出比EIU组显著减少(P＜0.01)。IF逆转LPS诱导的小胶质细胞激活，减轻视网膜神经节细胞及神经纤维损伤(P＜0.05)。②饥饿培养抑制LPS诱导的BV2细胞的磷酸化信号转导与转录激活因子1和3及诱导型一氧化氮合酶( inducible nitric oxide synthase, iNOS)的蛋白表达水平(P＜0.05)，显著降低iNOS、白介素-6等炎症因子的表达水平。结论：IF能够加速EIU炎症的消退，减轻组织结构的炎性破坏，抑制小胶质细胞的促炎型激活。

Objective: To investigate the protective effects of intermittent fasting (IF) on endotoxin-induced uveitis in mice and its potential anti-inflammatory mechanisms. Methods: Mice were randomly divided into three groups: control group (Ctr), endotoxin-induced uveitis (EIU) group, and IF + EIU group. The IF regimen followed a 16:8 fasting scheme (feeding from 9:00 to 17:00). The control group received intravitreal injections of PBS, while the other two groups received intravitreal injections of lipopolysaccharide (LPS). After modeling, fasting blood glucose and body weight of the mice were monitored. Inflammation levels were assessed using OCT and H&E staining. Retinal flat mounts were used for evaluating neuroinflammation. BV2 cells were divided into Ctr group, LPS group, and starvation (LG) + LPS group. The expression levels of related proteins and mRNA were detected using WB and RT-qPCR. Results: IF had no significant effect on body weight but caused a significant decrease in blood glucose, which gradually recovered. From the middle stage of the disease, mice in the IF intervention group show edretinal edema recovery, significantly reduced intravitreal inflammatory exudation and cell infiltration compared to the EIU group (P <0.01). IF reversed LPS-induced microglial activation and significantly alleviated damage to retinal ganglion cells and nerve fibers (P <0.05). Starvation culture significantly inhibited LPS-induced expression levels of p-STAT1/3 and iNOS proteins in BV2 cells (P <0.05) and significantly reduced the expression levels of inflammatory factors such as iNOS and IL-6. Conclusion: IF can accelerate the resolution of EIU inflammation, reduce inflammatory damage to tissue structures, and inhibit pro-inflammatory activation of microglia.

目的：调查眼科学硕士研究生批判性思维能力的现况，并了解其相关因素。方法：采用中文版评判性思维能力测量表(Critical Thinking Disposition Inventory-Chinese Version, CTDI-CV)对81名眼科学硕士研究生进行问卷调查，比较不同性别、年级、学位类别、学制的学生批判性思维能力的差异。结果：81名眼科学硕士研究生的CTDI-CV总分为(294.79±29.18)分，表明普遍具备积极的批判性思维能力，但“寻找真相”和“系统化能力”得分较低；不同年级与学位类型的眼科学硕士研究生的批判性思维能力等级分布存在差异。多因素线性回归显示，学位类型与眼科学硕士研究生的批判性思维能力相关。结论：眼科学硕士研究生普遍展现出正性的批判性思维特质，但在特定领域，其批判性思维能力仍有待提高，研究生教育应当采取针对性措施，培养研究生的批判性思维能力。

Objective: To investigate the current situation of critical thinking abilities of masters’ degree postgraduates in ophthalmology and identify the factors affecting the critical thinking abilities. Methods: Using the Critical Thinking Disposition Inventory-Chinese Version (CTDI-CV), a questionnaire survey was conducted among 81 masters’ degree postgraduates in ophthalmology. Results: The average total score of the CTDI-CV for the 81 master’s degree postgraduates in ophthalmology was 294.79±29.18, indicating a general possession of positive critical thinking abilities, yet scores in “Truth Seeking” and “Systematicity” were relatively low. There are differences in critical thinking abilities among master’s degree postgraduates in ophthalmology of various grades and degree categories. Multivariate linear regression indicates that degree categories is correlated with the critical thinking abilities of ophthalmology graduate students. Conclusions: The masters’ degree postgraduates in ophthalmology generally exhibit positive traits of critical thinking, yet there is room for improvement in specific areas. Postgraduate education should adopt targeted measures to cultivate the critical thinking abilities of postgraduates.
