小泪囊型慢性泪囊炎是泪道阻塞性疾病中的特殊亚型，目前尚无针对小泪囊的确切定义，传统内镜下泪囊鼻腔吻合术(endoscopic dacryocystorhinostomy, En-DCR)治疗小泪囊型慢性泪囊炎因泪囊体积小手术操作难度大、术后吻合口易闭锁和成功率低而被视为相对禁忌。本研究通过CT泪囊造影(CT dacryocystography, CT-DCG)三维精准测量、定义小泪囊(水平径≤3 mm、前后径≤3 mm、垂直径≤6 mm)，提出开放泪总管平面技术以扩大泪囊鼻腔吻合口，同时联合双管人工泪管植入术的En-DCR治疗方案，术后予以肾上腺皮质激素(激素)喷鼻剂辅助，显著提升手术疗效。

      研究纳入61例小泪囊型泪囊炎患者，术后9个月随访显示，解剖成功率达80. 33%(49/61)，功能成功率为75.41%(46/61)。术中开放泪总管平面技术有效扩大手术窗口；短期双管人工泪管植入(术后3个月取出)联合激素喷鼻剂使用可降低吻合口闭锁风险同时未增加肉芽增生和感染风险。与传统治疗相比，该方案突破小泪囊手术禁忌，为患者提供更优选择。

双眼视，即双眼同时工作、协调和整合视觉信息的能力，能够产生单一、立体和深度感的视觉体验，近年来在认知心理学和神经科学研究中逐渐受到越来越多的重视，尤其是在探讨其与执行能力之间复杂关联的方面。执行能力作为一项至关重要的认知功能，涉及多个方面，包括注意力、工作记忆、决策和问题解决等，这些因素共同影响着个体在日常生活和工作中的表现和效率。当前的研究表明，双眼视不仅在视觉信息的处理上发挥着关键作用，还对个体的执行能力产生了显著的影响。双眼视异常群体（如斜视、弱视患者）在执行功能测试中普遍表现出反应抑制延迟、工作记忆容量降低等特征。然而，现有文献中关于双眼视与执行能力之间关系的研究，特别是基于神经机制及其临床影响的系统性分析仍显得相对不足。为此，本文通过对现有研究的综述，深入探讨双眼视在执行能力中的作用，详细分析其背后的神经机制，并讨论这些发现对临床实践可能产生的影响。此外，文章还提出了未来研究的方向，以期更全面地理解双眼视与执行能力之间复杂的交互关系，从而为相关领域的研究提供新的视角和思路，推动这一领域的进一步发展。

Binocular vision, the ability of both eyes to work simultaneously, coordinate, and integrate visual information, can produce a unified, three-dimensional, and depth-perceptive visual experience. In recent years, it has garnered increasing attention in cognitive psychology and neuroscience research, particularly in exploring its complex relationship with executive functions. Executive functions, as a crucial cognitive capability, encompass various aspects, including attention, working memory, decision-making, and problem-solving, all of which collectively influence an individual's performance and efficiency in daily life and work. Current research indicates that binocular vision plays a key role not only in processing visual information but also has a significant impact on an individual's executive functions. Groups with binocular vision abnormalities (such as strabismus and amblyopia patients) generally exhibit characteristics like delayed response inhibition and reduced working memory capacity in executive function tests. However, existing literature on the relationship between binocular vision and executive functions, especially systematic analyses based on neural mechanisms and their clinical implications, remains relatively insufficient. Therefore, this article reviews existing research to delve into the role of binocular vision in executive functions, analyzes the underlying neural mechanisms in detail, and discusses the potential clinical implications of these findings. Additionally, the article proposes future research directions to comprehensively understand the complex interplay between binocular vision and executive functions, aiming to provide new perspectives and ideas for research in related fields and promote further development in this area.

真菌性角膜炎是我国常见的致盲性眼病，其中排前3位的致病病原菌分别为曲霉菌、镰刀菌以及念珠菌。念珠菌作为一种条件致病真菌，在宿主免疫功能低下或眼表微环境失衡时易引发机会性感染，其发病率因免疫抑制药物的滥用以及隐形眼镜佩戴的增加等因素逐年上升。在机会感染后，由于念珠菌本身以及生物膜形成的特殊作用，常导致其对现用系统性抗真菌药物，如伏立康唑、两性霉素B、伊曲康唑及氟康唑等耐药性增加。近年来，关于纳米材料介导的药物传递系统作用于治疗念珠菌角膜炎的研究日益增多，新型纳米材料通过作为抗真菌药物的载体，增加药物溶解度，延长眼表停留时间，加强生物膜、角膜穿透性，提高了抗真菌药物对念珠菌的抗菌作用，为解决念珠菌感染耐药性难题提供了新思路。文章综述了纳米聚合物、纳米颗粒、纳米凝胶、脂质体载体、纳米立方体、纳米微针和纳米胶束等新型纳米材料作为治疗念珠菌角膜炎的新型给药载体的研究现状与进展，突破传统疗法的局限，为改善目前临床存在抗真菌治疗药物有限的问题提供新的可行思路。

Fungal keratitis is a prevalent blinding ocular disease in China, with Aspergillus, Fusarium, and Candida ranking as the top three pathogenic fungi. As an opportunistic pathogenic fungus, Candida readily causes opportunistic infections when host immunity is compromised or the ocular surface microenvironment is imbalanced. The incidence of Candida keratitis has been rising annually due to factors such as the misuse of immunosuppressive drugs and increased contact lens wear. Following infection, Candida itself and the formation of biofilms contribute to enhanced resistance against currently used systemic antifungal agents, including voriconazole, amphotericin B, itraconazole, and fluconazole, posing significant challenges to clinical treatment.Recently, research on nanomaterials-mediated drug delivery systems for treating Candida keratitis has burgeoned. Novel nanomaterials, serving as carriers for antifungal drugs, enhance therapeutic efficacy by improving drug solubility, prolonging ocular surface retention time, penetrating biofilms, and enhancing corneal permeability. These advancements offer new strategies to address drug resistance in Candida infections. This article reviews the research status and progress of emerging nanomaterials—such as nanopolymers, nanoparticles, nanogels, liposomal carriers, nanocubes, nanoneedles, and nanomicelles—as innovative drug delivery vectors for Candida keratitis. By overcoming the limitations of conventional therapies, these nanomaterials provide feasible solutions to the clinical challenges of limited antifungal options and drug resistance. The integration of nanotechnology holds promise for revolutionizing the treatment of Candida keratitis and advancing precision medicine for ocular surface fungal infections.

Objective: To identify aqueous humor metabolic profiles associated with the progression of type 2 diabetes mellitus (T2DM) and diabetic retinopathy (DR), aiming to discover potential biomarkers for DR progression. Ultra-high performance liquid chromatography tandem quadrupole-electrostatic field orbitrap high-resolution mass spectrometry (UHPLC-HRMS) will be utilized in conjunction with machine learning (ML) for comprehensive analysis. Methods: A total of 78 patients with T2DM and 30 age- and gender-matched healthy controls were included. UHPLC-HRMS was used to identify metabolites in the aqueous humor of all participants. ML was employed to screen for metabolites associated with T2DM and DR progression, and predictive models were established. Results: After adjusting for covariates, 1,5-anhydroglucitol, tetradecyl sulfate, and n,n,n-trimethyl-5-aminovaleric acid identified as significant indicators for T2DM compared to controls (all P < 0.05). N-acetyltryptophan, linoleamide, oleamide, palmitic amide, valeric acid(FFA(5:0), and succinic acid emerged as predictors for DR progression (all P < 0.001). Metabolic pathway analysis revealed that "valine, leucine and isoleucine biosynthesis", "arginine biosynthesis," and "cysteine and methionine metabolism" were the most enriched pathways for T2DM. Predictive models achieved R² values of 81.3%, and 74% for T2DM and DR progression, respectively. Conclusions: Metabolomic combined with ML effectively uncovered metabolic characteristics associated with T2DM and DR progression. Linoleamide and oleamide represent promising potential biomarkers for DR progression, offering new opportunities for diagnosis and personalized treatment of DR.

慢性中心性浆液性脉络膜视网膜病变(cCSC)以广泛的脉络膜视网膜异常为特征，包括脉络膜血管扩张及其引发的弥漫性视网膜色素上皮病变和浆液性视网膜脱离，常累及黄斑区，引起视功能损害。传统观点认为其可能由急性CSC演变而来，但近期研究显示两者在临床上存在明显差异。其病情反复、迁延，预后较差。随着光学相干断层扫描血管造影(OCTA)、超广角成像和en face重建成像等新多模式影像(MMI)技术的出现和人工智能及机器学习的发展，更多有意义的cCSC影像学特征不断出现。文章详细介绍了cCSC在眼底成像、眼底自发荧光(FAF)、光学相干断层扫描(OCT)、眼底荧光素血管造影(FFA)、吲哚菁绿血管造影和OCTA等影像技术中的表现，并探讨了人工智能在识别CSC分类及其OCT 生物标志物等方面的应用。不同影像技术在cCSC的诊断和研究中各有优势，如FAF可能是评估疾病进展及变化的有效手段，OCT可更直观地观察视网膜结构的改变，FFA是识别渗漏点的重要检查手段，而OCTA可能是评估脉络膜微循环的的最佳手段等。这些MMI研究进展为深入了解cCSC的病理生理机制及临床特征提供了重要线索，有助于提高诊断的准确性和效率，改善患者的预后和生活质量。

Chronic central serous chorioretinopathy (cCSC) is characterized by extensive retinochoroidal abnormalities. This includes difuse retinal pigment epitheliopathy and serous retinal detachment associated with choroidal vasodilatation, ofen involving the macula and cause visual impairment. It was originally considered that it might evolve from acute CSC, but recent studies have shown significant clinical differences between the two. It tends to recur, be prolonged, and have an unfavorable prognosis. With the advent of new multimodal imaging (MMI) techniques such as optical coherence tomography angiography (OCTA), ultra-wide-feld imaging, and en face reconstruction imaging, along with the advancement of artificial intelligence and machine learning, more significant cCSC imaging characteristics have been constantly emerging. Tis article provides a comprehensive overview of cCSC’s imaging features across various modalities, including fundus photography, fundus autofluorescence (FAF), optical coherence tomography (OCT), fuorescein angiography (FFA), indocyanine green angiography, and OCTA. It also explores the application of artifcial intelligence in identifying CSC classifications and OCT biomarkers. Different imaging techniques have their own advantages in the diagnosis and study of cCSC, such as FAF being an efective means to assess disease progression and changes, OCT providing a more intuitive observation of retinal structural changes, FFA being an important tool for identifying leakage points, and OCTA possibly being the best means to assess choroidal microcirculation. Tese MMI research advancements ofer crucial insights for clinicians, aiding in more accurate diagnosis and efective treatment, thereby potentially improving patient outcomes and quality of life.

目的：评估炎非感染性葡萄膜炎继发炎性脉络膜新生血管(inflammatory choroidal neovascularization, iCNV)的临床特征及眼底多模式影像表现。方法：采用回顾性观察性研究，采用眼底荧光素血管造影(fundus fluorescein angiography, FFA)、吲哚菁绿血管造影(Indocyanine green angiography, ICGA)、谱域相干光断层扫描(spectral domain optical coherence tomography, SD-OCT)联合光学相干断层扫描血管成像(optical coherence tomography angiography, OCTA)等多种眼底影像学方法，对纳入患者的眼底进行检查，分析非感染性iCNV的面积、分型、位置及形态等影像学特征与临床特征的关系。结果：研究共纳入39例患者，对48只患眼中的51处iCNV病灶进行了评估。纳入患者年龄为(35.28±13.62)岁。其中3例患眼出现多灶性CNV。SD-OCT显示92.16%(47/51)的iCNV为2型CNV，17.65%(9/51)的iCNV出现海绵征，13.72%(7/51)的iCNV伴有局灶脉络膜凹陷。ICGA造影期间，74.50%的iCNV病灶(38/51)伴有弱荧光病灶，25.49%的病例(13/51)显示脉络膜高通透性表现。OCTA enface图像显示iCNV形态多样，包括焦点状(15例，29.41%)、盘状/海扇状(16例，31.37%)、枯树状(9例，17.65%)、星状(9例，17.65%)及弥漫网状(2例，3.92%)。其中，枯树状及星状iCNV提示iCNV为非活动性(P＜0.01)。结论：非感染性iCNV与炎性病灶关系密切，在SD-OCT，ICGA上皆具特征性的影像表现。OCTA能直观地观察到iCNV的形态。这些多模式影像特征为临床医生提供了对于非感染性iCNV重要的鉴别诊断依据，有助于制定有效的诊疗方案。

Objective: To evaluate the clinical characteristics and multimodal imaging features of non-infectious inflammatory choroidal neovascularization (iCNV). Methods: In this study retrospective, observational study, multimodal imaging examinations, including fluorescein angiography (FFA), indocyanine green angiography (ICGA), spectral-domain optical coherence tomography (SD-OCT), and optical coherence tomography angiography (OCTA), were used to observe the morphology of non-infectious iCNV in patients diagnosed with uveitis. The area of iCNV, CNV types, CNV morphology and other imaging characteristics were further analyzed. Results: A total of 39 patients were included, with 48 affected eyes and 51 iCNV were identified. The average age of the included patients was 35.28±13.62 years. Among the affected eyes, 3 presented with multifocal CNV, and 92.16% of iCNV were classified as type 2 CNV. iCNV exhibited diverse morphologies, including focal-like pattern (15 cases, 29.41%),sea-fan pattern(16 cases, 31.37%), dead-tree pattern CNV(9 cases, 17.65%), stellar pattern (9 cases, 17.65%), and diffuse reticular (2 cases, 3.92%). Notably, tree-like and stellar pattern iCNV showed a significant correlation with non-active CNV (P < 0.01). Conclusions: Non-infectious iCNV is closely related to inflammatory lesions, exhibiting characteristic imaging features on SD-OCT and ICGA. OCTA allows for direct observation of the morphology of iCNV. These multimodal imaging characteristics provide important diagnostic criteria for clinicians, aiding in the formulation of effective treatment plans.

随着多模式影像技术的应用，年龄相关性黄斑变性(age related macular degeneration, AMD)的一种特殊亚型：表皮玻璃疣(cuticular drusen)被发现，其与AMD尤其是非渗出性AMD又称干性(dry)AMD进展密切相关。但目前聚焦于AMD合并表皮玻璃疣的多模式影像特点等的相关文献较少，因此研究和阐明表皮玻璃疣的多模式影像特点、与其他AMD亚型玻璃疣的鉴别诊断、病理生理机制、治疗方法等具有重要的临床意义。运用多模式影像可以看到表皮玻璃疣呈双眼对称的无数散在的大小均匀的黄色视网膜下结节，典型的“星空状”荧光素钠眼底血管造影(fundus fluorescein angiography, FFA)表现， 以及光学相干断 层成像(optical coherence tomography, OCT)中视网膜色素上皮(retinal pigment epithelium, RPE)和Bruch膜之 间的锯齿状隆起。AMD合并表皮玻璃疣患者的分布特点个体差异很大，容易与AMD其他亚型的玻璃疣混淆，需要与硬性玻璃疣、软性玻璃疣、大胶质玻璃疣、Sorsby眼底营养不良(Sorsby's fundus dystrophy , SFD) 等相鉴别。研究表明表皮玻璃疣具有遗传性的类似动脉粥样硬化的发病机制，与RPE分泌的大型脂蛋白颗粒的堆积密切相关。未来可能会有针对补体系统的药物用于延缓表皮玻璃疣相关病变的进展。文章就表皮玻璃疣的临床表现、多模式影像的典型特点、鉴别诊断、遗传学基础、病理生理学发病机制、 并发症以及临床诊疗策略进行综述。

With the application of multimodal imaging techniques, a specific subtype of age-related macular degeneration (AMD),
known as cuticular drusen, has been identified. This subtype is closely associated with the progression of AMD, particularly non-exudative AMD, also referred to as dry AMD. However, there is a scarcity of literature focusing on the multimodal imaging characteristics of AMD combined with cuticular drusen. Therefore, studying and elucidating the multimodal imaging features of cuticular drusen, its differential diagnosis from other AMD subtypes of drusen, pathophysiological mechanisms, and treatment methods holds significant clinical importance. Multimodal imaging reveals cuticular drusenas numerous, symmetrical, evenly sized, yellow subretinal nodules in both eyes, exhibiting a typical "stars-in-the-sky" appearance on fluorescein angiography (FFA) and zigzag elevations between the retinal pigment epithelium (RPE) and Bruch's membrane on optical coherence tomography (OCT). The distribution characteristics of AMD patients with cuticular drusen vary greatly among individuals and can easily be confused with drusen from other AMD subtypes, so the differentiation from hard drusen, soft drusen, large colloidal drusen, and Sorsby's fundus dystrophy (SFD) is necessary. Studies suggest that cuticular drusen have a genetic, atherosclerosis- like pathogenesis which closely related to the accumulation of large lipoprotein particles secreted by the RPE. Future therapies targeting the complement system maybe employed to delay the progression of cuticulardrusen-related lesions. This article reviews the clinical manifestations, typical multimodal imaging features, differential diagnosis, genetic basis, pathophysiological mechanisms, complications, and clinical management strategies of cuticulardrusen.

糖尿病视网膜病变(diabetic retinopathy, DR)作为糖尿病的一种常见并发症是导致工作年龄人群失明的主要原因。血糖变异性(glycemic variability, GV)指血糖波动的程度。最新研究表明，GV与糖尿病患者的代谢状况和微血管病变密切相关。该文综述了GV对DR的影响及其研究进展。GV是指血糖水平在高点和低点之间波动的不稳定状态，分为长期GV和短期GV。长期GV主要通过空腹血糖(fasting plasma glucose, FPG)、餐后血糖(postprandial plasma glucose, PPG)和糖化血红蛋白(glycated hemoglobin, HbA1c)评估，短期GV则通过血糖标准差(standard deviation, SD)、变异系数(coefficient of variation, CV)、低血糖指数(low blood glucose index, LBGI)等指标量化。研究表明，GV是糖尿病大管和微血管并发症的重要风险预测因子，与冠状动脉综合征、心肌梗死、脑卒中、糖尿病肾病、周围神经病变等密切相关。在DR方面，GV可能是其进展的风险因素，高GV会加剧氧化应激、炎症反应、内皮功能障碍和新生血管生成，从而促进DR的发展。治疗策略包括动态血糖监测系统、药物干预(如基础胰岛素、阿格列汀等)、合理饮食和运动等，这些方法可改善GV，降低并发症风险，提高患者预后和生活质量。

Diabetic retinopathy (DR) is a common complication of diabetes and is a leading cause of blindness in the working-age population. Glycemic variability (GV) refers to the degree of fluctuation in blood glucose levels. Recent studies have shown that GV is closely related to the metabolic status and microvascular complications in patients with diabetes. This article reviews the impact of glycemic variability (GV) on diabetic retinopathy (DR) and the latest research progress.GV is defined as the unstable state of blood glucose levels fluctuating between highs and lows, which is categorized into long-term GV and short-term GV. Long-term GV is mainly assessed through fasting plasma glucose (FPG), postprandial plasma glucose (PPG), and glycated hemoglobin (HbA1c). Short-term GV is quantified by indicators such as the standard deviation of blood glucose (SD), coefficient of variation (CV), and low blood glucose index (LBGI).Studies have shown that GV is an important risk predictor for both macrovascular and microvascular complications in diabetic patients, being closely associated with conditions such as coronary artery syndrome, myocardial infarction, stroke, diabetic nephropathy, and peripheral neuropathy. Regarding DR, GV is likely a risk factor for its progression. High GV can exacerbate oxidative stress, inflammatory responses, endothelial dysfunction, and neovascularization, thereby promoting the development of DR.Treatment strategies include continuous glucose monitoring systems, pharmacological interventions (such as basal insulin, alogliptin, etc.), as well as proper diet and exercise. These approaches can improve GV, reduce the risk of complications, and enhance patients' prognosis and quality of life.
