泪道阻塞是临床常见的眼科疾病，主要表现为溢泪、反复感染等症状，严重影响患者的生活质量。传统治疗方法主要采用硅胶或金属支架置入术，这些材料虽然能够暂时维持泪道通畅，但由于其不可降解性、容易移位、易形成生物膜导致感染等固有缺陷，往往需要二次手术取出，给患者带来额外的痛苦和经济负担。随着材料科学和生物医学工程的发展，新型支架材料的研发为解决这些问题提供了新的思路。文章聚焦新型材料如可降解材料、3D打印个性化支架、复合材料及表面改性技术等，这些材料可通过材料降解、精准适配或多功能整合提升临床疗效，但在降解速率调控、3D打印精度及成本方面仍面临诸多挑战。此外，这些新技术的长期安全性和有效性还需要更多临床数据的支持，在未来仍需不断探索，开发更精准的降解速率调控方法，优化3D打印流程以提高精度，降低材料制备的成本，探索更高效的复合材料制备技术。同时，要加强基础研究，推动更多创新技术在临床的应用，开发出更安全、更有效的新型泪道支架材料，为泪道阻塞患者提供更优质的治疗方案，推动泪道疾病治疗向精准微创化方向发展。

Lacrimal duct obstruction is a common clinical ophthalmic condition characterized by symptoms such as epiphora and recurrent infections, significantly impairing patients' quality of life. Traditional treatments primarily involve the implantation of silicone or metal stents. While these materials can temporarily maintain lacrimal duct patency, their inherent drawbacks—such as non-degradability, susceptibility to displacement, and tendency to form biofilms leading to infections—often necessitate secondary surgeries for removal, imposing additional physical and financial burdens on patients.Advances in materials science and biomedical engineering have introduced novel stent materials as potential solutions to these challenges. This article focuses on emerging materials such as biodegradable polymers, 3D-printed personalized stents, composite materials, and surface modification technologies. These innovations can enhance clinical outcomes through material degradation, precise customization, or multifunctional integration. However, challenges remain in regulating degradation rates, improving 3D printing precision, and reducing costs.Furthermore, the longterm safety and efficacy of these technologies require more clinical data for validation. Future research should explore more precise degradation rate control methods, optimize 3D printing processes to enhance accuracy, lower material production costs, and develop more efficient composite material fabrication techniques. Concurrently, strengthening fundamental research and promoting the clinical application of innovative technologies will be crucial to developing safer and more effective lacrimal duct stent materials. Such advancements will provide superior treatment options for patients with lacrimal duct obstruction and drive the field toward minimally invasive and precision medicine approaches.

Purpose：To analyze the disease spectrum of emergency cases at an ophthalmology hospital in Tianjin, offering evidence-based support for standardizing diagnostic procedures and rationing emergency medical resources. Methods: Reviewed clinical data of patients at the hospital's emergency department from January 2019 to December 2023, covering demographics, visit timings, seasonal distribution, and preliminary diagnoses. Results: A total of 26,077 ophthalmology emergency patients were included, with a male-to-female ratio of 1.12:1 and an average age of 36.82±15.44 years. Most patients were aged <14 years (26.74%) and 31~40 years (21.03%). Daily visits peaked at 10:00~12:00 (11.06%), 14:00~16:00 (10.41%), and 20:00~22:00 (10.43%), and were lowest at 05:00~07:00 (4.83%). April had the fewest visits (3.87%), August the most (11.61%), and summer accounted for the highest quarterly proportion (31.74%). The top 10 preliminary diagnoses were led by conjunctivitis (39.58%) and xerophthalmia (14.32%). Compared to 2019, the top 10 preliminary diagnoses dropped significantly in 2020 and 2021 (both P<0.001), 2020 95%CI[-0.98~-0.68]、2021 95%CI[-0.54~-0.11]. Similarly, these diagnoses were significantly lower in summer, autumn, and winter than in spring (all P<0.001), summer 95%CI[-0.32~-0.08]、autumn 95%CI[-0.39~-0.14]、winter 95%CI[-0.54~-0.30]. In conjunctivitis cases, winter incidence was significantly lower than in spring and summer (both P<0.001). Gender distribution in the top 10 diagnoses was statistically significant (P<0.001), 95%CI[-0.08~-0.03] and [-0.08~-0.04] . Compared to those aged <14, other age groups showed a downward trend in the top 10 preliminary diagnoses (all P<0.001), 14~20 95%CI[-0.88~-0.43]、21~30 95%CI[-1.01~-0.65]、31~40 95%CI[-1.10~-0.82]、41~50 95%CI[-0.97~-0.66]、51~60 95%CI[1.71~-1.38]、61~70 95%CI[-1.45~-1.08]、71~80 95%CI[-1.36~-0.80]、>80 95%CI[-1.44,-0.22]. Conclusions: Ophthalmology emergency patients are mainly children and middle-aged men, with those <14 years old at higher risk. Visit times follow a "three-peak-one-valley" pattern. Most diagnoses are non-urgent conditions like conjunctivitis and xerophthalmia. Conjunctivitis shows marked seasonality, peaking in spring and summer. Total ophthalmology emergency visits declined in 2020 and 2021 versus 2019, particularly for conjunctivitis and xerophthalmia, partially recovering in 2022.

Objective: Review the ocular manifestations of patients with neurofibromatosis type 2 (NF2), and analyze the clinical and imaging features of the ocular lesions in NF2, so as to facilitate the early diagnosis of this disease. Methods: The complete medical records of 1 case from Shenzhen Eye Hospital and 3 cases of NF2 from Zhongshan Ophthalmic Center were collected. Results: All four patients were first diagnosed in ophthalmology due to eye symptoms and met the Manchester diagnostic criteria. Of the four patients, three were NF2 early hairstyles (<20 years old), one was late hairstyle (>20 years old), and the male-to-female ratio was 1:1. Three patients were first diagnosed in the ophthalmology department due to decreased visual acuity, and one patient was first diagnosed due to diplopia. Optical coherence tomography (OCT) examinations were performed on three patients, which showed that there were two cases of retinal hamartoma, two cases of epiretinal membrane, two cases of optic disc elevation, and one case of thinning of the retinal nerve fiber layer and ganglion cell layer. Other manifestations included two cases of paralytic strabismus, one case of diplopia, one case of cataract, one case of thickening of the retrobulbar optic nerve, and one case of orbital tumor. Conclusions: The ocular manifestations of NF2 are diverse and can precede neurological symptoms and hearing loss. Detailed ophthalmic examinations and imaging studies are highly valuable for early diagnosis in young patients, aiding in the selection of a better treatment plan.

       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.

Among the 1185 patients, 516 were female and 483 were male ( 43.54 % vs 40.76 % ) after excluding the unknown gender. After excluding patients with unknown age, the incidence of ADRs was higher in patients aged 65~ < 80 years old ( 221 cases, 18.65 % ), 50~< 65 years old ( 176 cases, 14.85 % ), and 3~ < 13 years old ( 140 cases, 11.81 % ). The ADRs with high incidence of cyclopentolate hydrochloride eye drops were ocular organ diseases ( 767 cases, 64.73 % ), nervous system diseases ( 254 cases, 21.43 % ) and gastrointestinal system diseases ( 228 cases, 19.24 % ). Conclusions: Cyclopentolate hydrochloride eye drops can cause local and systemic adverse reactions. In clinical use, the patient 's disease history and medication history should be asked in detail, and medication monitoring should be strengthened to improve the safety of patient medication.
