Objective: This study aimed to analyze the formation of ostium granulomas following endonasal endoscopic dacryocytostomy (DCR) in patients with chronic dacryocystitis and to evaluate the efficacy of excision combined with triamcinolone (TA) injection for treating ostium granulosis after endoscopic dacryocystorhinostomy. Methods: A restrospective analysis was conducted on 98 patients (115 eyes) with chronic dacryocystitis who underwent endoscopic dacryocystorhinostomy.  Postoperative growth of the ostium granulomas was monitored, and clinical characteristics were compared between patients with and without ostium granulomas. Among these, 26 cases (31 eyes) of ostium granuloma were identified and randomly assigned to either an excision combined with triamcinolone injection group (13 cases with 16 eyes) or excision-only group (13 cases with 15eyes) based on the treatment method. The effective rates between two groups was compared. Results: Ostium granulomas occurred in 31 eyes (26.96%). The cure rate and improvement rate in the excision combined with TA group were 93.75% and 6.25%, respectively, whereas in the excision-only group, they were 60% and 33.33%. These differences were statistically significant (P < 0.05).  Conclusions: Excision combined with intralesional triamcinolone acetonide injections proved effective in promoting the regression of ostium granuloma after DCR.

目的：分析日间病房模式下原发性获得性鼻泪管阻塞(primary acquired nasolacrimal duct obstruction, PANDO)患者行经鼻内镜下泪囊鼻腔吻合术（endoscopic dacryocystorhinostomy, En-DCR）的术后自我护理现状并进行早期效果评价。方法：纳入2021年11月—2022年8月在中山大学中山眼科中心眼整形与泪道科日间病房行En-DCR手术治疗的90例PANDO患者，术后常规给予术后自我护理指导。术后1个月复查，采用调查问卷的方式记录患者的术后自我护理情况及不适症状，评估患者手术效果，并进一步探究术后自我护理因素与手术效果及术后不适症状的相关性。结果：90例行En-DCR手术治疗的PANDO患者共计90眼，术后1个月手术总成功率为92.22%（其中治愈率为65.56%、好转率为26.67%）。术后自我护理与手术效果的特征分析显示，术后遵嘱鼻腔冲洗每日至少1次（P = 0.002）、遵医嘱喷鼻每日至少1次（P = 0.008）、术后无上呼吸道感染（P = 0.047）的患者手术效果更好。术后自我护理与术后不适症状的特征分析显示，每日至少1次鼻腔冲洗（P = 0.006）和义管在位（P = 0.003）的患者术后不适症状较少。同时对置管患者进行心理负担相关性分析，结果显示置管不适与心理负担呈正相关（r = 0.421, P < 0.001）。结论：在日间病房模式下，医护人员对En-DCR术后患者进行详细的自我护理指导，有助于患者的术后恢复及保证良好的手术疗效。指导重点包括术后1个月内每日至少1次鼻腔冲洗，规律使用抗炎喷鼻剂并防止上呼吸道感染；另外应重点关注泪道置管患者术后局部不适症状，针对术后不适症状优化用药，使用互联网护理门诊或电话随访做好护理指导和心理疏导，促进患者术后康复。

Objective: To investigate  postoperative self-care practices and evaluate the early outcomes of patients with Primary Acquired Nasolacrimal Duct Obstruction (PANDO) undergoing Endoscopic Dacryocystorhinostomy (En-DCR) in a day ward setting. Methods: 90 PANDO patients who underwent En-DCR surgery at the Oculoplastic and Lacrimal Surgery day ward at Zhongshan Ophthalmic Center, Sun Yat-sen University, between November 2021 and August 2022, were enrolled in this study. All patients received standardized postoperative self-care instructions. At the one-month follow-up, a questionnaire survey was used to record patients' self-care adherence to self-care practices, postoperative discomfort symptoms, and assess surgical outcomes. Furthermore, the correlation between self-care factors and surgical outcomes/discomfort symptoms was explored. Results: A total of 90 eyes from 90 PANDO patients undergoing En-DCR were included. The overall surgical success rate at one month was 92.22% , comprising a cure rate of 65.56% and an improvement rate of 26.67%. Analysis of self-care practices related to surgical outcomes showed significantly better results in patients who adhered to nasal irrigation at least once daily (P = 0.002), used prescribed nasal spray at least once daily (P = 0.008), and avoided upper respiratory tract infections (P = 0.047). Regarding postoperative discomfort, patients who peformed nasal irrigation at least once daily (P = 0.006) and had the lacrimal stent (tube) in situ (P = 0.003) experienced significantly fewer symptoms. Furthermore, correlation analysis in stented patients indicated a positive correlation between stent discomfort and psychological burden (r = 0.421, P < 0.001). Conclusion: In the day ward model, detailed self-care guidance provided by healthcare professionals for En-DCR patients contributes to postoperative recovery and ensures favorable surgical outcomes. Key instructions include performing nasal irrigation at least once daily, using anti-inflammatory nasal spray regularly, and preventing upper respiratory infections during the first postoperative month. Additionally, particular attention should be paid to localized discomfort in patients with lacrimal stents. Optimizing medication regimens for discomfort, utilizing internet-based nursing clinics or telephone follow-ups for guidance and psychological support are crucial to promote postoperative rehabilitation.

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.
