中心性浆液性脉络膜视网膜病变（central serous chorioretinopathy，CSC）是一种以脉络膜增厚、血管通透性增加为特征的脉络膜谱系疾病，所以对脉络膜的观察对于CSC的监测和治疗非常重要。随着光学相干断层扫描成像（optical coherence tomography，OCT）的发展，对脉络膜的认识有了显著提升，也让我们更深刻地理解了它在眼后段疾病中的重要作用，提高了对各种脉络膜视网膜疾病的诊断能力。近年来，随着扫频源光学相干断层扫描（swept source optical coherence tomography，SS - OCT）及扫频源光学相干断层扫描血流成像（swept source optical coherence tomography angiography，SS - OCTA）的发展，其扫描波长、深度、广度及扫描速度均显著提升，实现了对脉络膜结构的无创定量化评估，推进了对CSC等脉络膜谱系疾病的病理机制的认识和临床管理。文章就近年SS-OCT及SS-OCTA在 CSC 中的应用及研究进展进行总结。主要进展有：发现CSC脉络膜增厚不仅局限于黄斑区，且发现其脉络膜血管及基质成分均显著增加；CSC为双眼受累，而表现为单眼症状；涡静脉回流障碍机制在该疾病中起到关键作用；SS-OCT能进一步对后极部的视网膜下积液进行监测和分析；发现了急性与慢性CSC脉络膜相关参数的改变的不同；最后探究了巩膜机制在该疾病中可能起到的作用。

Central serous chorioretinopathy (CSC) is one of the choroidal spectrum diseases, characterized by choriod thickening and increased vascular permeability. Therefore it is very important to observe choroid, as this allows us to monitor it and formulate an appropriate therapeutic schedule. With the development of optical coherence tomography (OCT), our understanding of choroid has been significantly improved. We have got a deeper insight into its important role in posterior diseases, and also the diagnostic capability for choroidal and retinal diseases has also improved. In recent years, the development of swept source optical coherence tomography (SS-OCT) and swept source optical coherence tomography angiogrphy (SS-OCTA) has further advanced our ability to assess choroidal conditions. These technologies offer enhanced scanning wavelengths, depth, breadth, and scanning speed, enabling non-invasive quantitative assessment of choroidal structures. This has advanced our understanding of the pathophysiological mechanisms and clinical management of CSC and other choroidal spectrum diseases.This review summarizes the application of swept source optical coherence tomography (SS - OCT) and swept source optical coherence tomography angiography (SS - OCTA) in CSC and its research progress. The main advancements include: choroidal thickening in CSC is not limited to macular area, both choroidal vascular and stromal components are significantly increased; CSC can affect both eyes, although it often presents with unilateral symptoms; impaired vortex vein outflow plays a key role in the pathogenesis of this disease; SS-OCT can further monitor and analyze subretinal fluid accumulation in the posterior pole; differences in changes in choroidal parameters between acute and chronic CSC have been identified; and finally, the potential role of scleral mechanisms in this disease have been explored.

目的：分析视网膜前巨噬细胞样细胞（epiretinal macrophage-like cells，eMLC）和视网膜脉络膜血流在急性黄斑神经视网膜病变（acute macular neuroretinopathy，AMN）患眼的临床特征。方法：回顾性分析2022年12月—2023年5月在中山大学中山眼科中心就诊的病程2周内的AMN患者21例（37眼）及年龄匹配的健康对照组33例（38眼）的临床资料。通过黄斑区内界膜上3 μm的en face 光学相干断层扫描（optical coherence tomography，OCT）分层信息对eMLC进行半自动分析提取和定量，同时测量OCT血管成像（optical coherence tomography angiography，OCTA）6 mm x 6 mm 的黄斑区域内视网膜脉络膜血流参数进行分析对比。结果： AMN组黄斑区eMLC数量为（329.78±77.38）个，密度为（9.16±2.15）个/mm²，均较对照组（202.63±41.72）个、（5.63±1.16）个/mm²增加（均P＜0.001）。AMN组浅层和深层视网膜血流密度分别为（33.00±6.49）%和（32.59±7.41）%，均较对照组（36.18±5.63）%和（37.08±5.65）%减少（均P＜0.05）。视网膜全层中心凹无血管区（foveal avascular zone，FAZ）面积、视网膜全层血流密度、脉络膜毛细血管和脉络膜大中血管血流密度在两组间比较差异无统计学意义（P＞0.05）。浅层及深层视网膜血流密度和FAZ面积对eMLC密度无影响（P＞0.05）。13例AMN患者（23眼）1个月时的随访资料显示：AMN组末次随访时eMLC数量为（248.70±59.88）个、密度为（6.91±1.66）个/mm²较初次就诊时（307.87±82.98）个和（8.55±2.30）个/mm²减少（均P＜0.001），但仍高于同期对照组（176.58±27.89）个和（4.91±0.77）个/mm²（均P＜0.001）。视网膜和脉络膜血流参数较初次就诊时比较差异无统计学意义（均P＞0.05）。结论：AMN患眼中eMLC异常增多和聚集，同时存在轻度的视网膜血流密度下降，但无脉络膜血流参数变化，且eMLC变化与AMN病程相关但与视网膜血流变化无关，提示eMLC所代表的炎症可能独立参与了AMN的发生。

Objective: To investigate the clinical characteristics of epiretinal macrophage-like cells (eMLC) and retinochoroidal blood flow in eyes affected by acute macular neuroretinopathy (AMN). Methods: This retrospective case series study included 21 (37 eyes) patients diagnosed with AMN and 28 (33 eyes) healthy age-matched subjects. A 3 mm En-face optical coherence tomography (OCT) slab on the inner limiting membrane of the macular region was used to visualize and binarize the MLCs. The MLCs were binarized and quantified using a semiautomated method. Optical coherence tomography angiography (OCTA) was used to evaluate the perfusion status and obtain the structural data of macular within a 6 x 6 mm² macular region. Results: The number and density of macular eMLC in AMN eyes were significantly increased in comparison to control eyes: 329.78±77.38 vs. 202.63±41.72, (P＜0.001) and 9.16±2.15 cells/mm² vs. (5.63±1.16) cells/mm² (P＜0.001). In the macular region, both superficial and deep retinal vessel densities were significantly lower in the AMN eyes than in the control eyes: (33.00±6.49)% vs. (36.18±5.63)% (P=0.040); (32.59±7.41)% vs. (37.08±5.65)% (P=0.008). There were no significant differences in the vessel densities and foveal avascular zone (FAZ) area of full retina and choroidal vessel density between the two groups (P＞0.05). The eMLC density was not associated with the superficial and deep retinal FAZ area and vessel densities (all P＞0.05). At the one-month follow-up data of 13 patients (23 eyes), the number and density of macular eMLC were significantly lower in comparison to the initial visit: 248.70±59.88 vs. 307.87±82.98, P＜0.001 and (6.91±1.66) cells/mm² vs. (8.55±2.30) cells/mm² (P＜0.001). However, the number and density of macular eMLC are still noticeably higher than those of the control group during the same timeframe: 248.70±59.88 vs. 176.58±27.89 (P＜0.001) and (6.91±1.66) cells/mm² vs. (4.91±0.77) cells/mm² (P＜0.001). There was no significant difference in the vessel density of retina and choroidal during the follow-up (P＞0.05 ). Conclusions: The aggregation and activation of eMLC and a mild decrease in retinal blood flow density are observed in AMN, yet there is no corresponding shift in choroidal vessel density. The changes of eMLC are linked to the course of AMN, but they are not related to retinal vessel density. The inflammatory response represented by eMLC might independently contribute to the pathogenesis and progression of AMN.

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 retrospective 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).  Conclusion: Excision combined with intralesional triamcinolone acetonide injections proved effective in promoting the regression of ostium granuloma after DCR.

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 performed 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.

Age-related cataract is the leading blinding eye disease in the world, and surgery is the only effective treatment. The good recovery of vision after cataract surgery depends not only on the patients’ ocular conditions but also on the surgical technique and quality management level of medical institutions. Standard surgical procedures, the accurate measurement and calculation of intraocular lens (IOL) power, and professional perioperative management are the keys to restoring the sight of patients. In addition, the National Health Commission proposed in the "Work Plan for Strengthening the Cataract Surgery Capacity Building of County-level Hospitals (2025-2027)" that the ability of county-level hospitals to perform cataract surgery should be further improved by strengthening the construction of equipment and facilities, assisting county-level hospitals in carrying out personnel training, and establishing standardized surgical system. Therefore, in order to standardize cataract surgery procedures, ensure the safety of the surgery and reduce surgical complications, under the leadership of the Guangdong Medical Association, the Zhongshan Ophthalmic Center of Sun Yat-sen University, in conjunction with 21 other medical institutions in Guangdong Province and 35 authoritative experts, jointly drafted this group standard. On the basis of referring to the domestic and international standards for cataract surgery and combining with the current situation of cataract surgery in Guangdong Province, they jointly determined this group standard. This group standard systematically describes the basic requirements for the software and hardware conditions of age-related cataract surgery, the indications and contraindications of the surgery, formulates the standard surgical procedures and quality control standards for cataract surgery, and introduces the prevention and treatment of complications or adverse reactions, providing guidance for all qualified medical institutions at different levels to carry out cataract surgery and quality assessment.

视网膜色素上皮脱离(pigment epithelial detachment, PED)是年龄相关性黄斑变性(age-related macular degeneration, AMD)的常见临床体征之一，也是反应患者视力预后的重要生物标志物。随着眼底影像技术的快速发展，PED分型依据从单一视角逐渐转变为多模式影像。眼底荧光素血管造影对PED分型进行了初探，吲哚菁绿血管造影的应用加强了对PED内血管成分的判断，光学相干断层扫描的问世使PED结构和内容物的可视化水平得到提高，多模式影像的应用则兼顾了对PED血管特性及内容物性质的判断，为进一步认识PED的发病机制和病程特征提供了重要支持，促进PED分型体系不断更新。PED现有分型种类繁多，概念之间存在交叉。文章通过回顾国内外关于AMD相关的PED研究现状，对分型系统、多模式影像特征及最新影像进展进行汇总，为PED的标准化诊疗和未来研究方向提供了系统参考，以期推动PED相关临床和研究的深入发展。

Pigment epithelial detachment (PED) is one of the common manifestations of age-related macular degeneration (AMD), posing a significant threat to the patients’ vision. With the rapid advancement of imaging technology, the visualization of PED structure and content has improved considerably. The diagnostic methods and classification systems of PED are also evolving, enabling researchers to further explore its pathogenesis and disease course. However, current PED classification systems are numerous, with overlapping concepts that may cause confusion. This article reviews existing relative literature on AMD-related PED, summarizing the classification systems, multimodal imaging features, and recent imaging advances. The objective of this article is to standardize the diagnosis and guide treatment of PED, to provide systematic reference to the future research, ultimately advancing both clinical and research efforts related to PED.

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.

目的：回顾2型神经纤维瘤病(neurofibromatosis type 2, NF2)患者的眼部表现，分析NF2眼部病变的临床和影像学特征，以助该病的早期诊断。方法：收集来自深圳市眼科医院的1例和来自中山眼科中心的3例NF2患者完整的临床资料并进行总结分析。结果：这4例患者均因眼部异常首诊于眼科且符合曼彻斯特诊断标准。4例患者中，3例为NF2早发型(<20岁)，1例为晚发型(>20岁)，男女比例1∶1。3例患者因视力下降、1例患者因复视首诊于眼科。3例行眼底光学相干断层成像(optical coherence tomography, OCT)检查显示，视网膜错构瘤2例，视网膜前膜2例，视盘隆起2例，视网膜神经纤维层和节细胞层变薄1例。其他表现包括麻痹性斜视2例，复视1例，白内障1例，球后段视神经增粗1例，眼眶肿瘤1例。结论：NF2的眼部表现多种多样，可出现在神经症状和听力损失之前。详细的眼科检查及影像学检查对年轻患者的早期诊断非常有价值，有助于选择更好的治疗计划。

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.
