Objective: To understand the infection status of four blood-borne pathogens among ophthalmology patients in South China and the distribution of positive patients across different eye diseases. Methods: A retrospective analysis of data from outpatient and inpatient or surgical ophthalmic patients who underwent screening for hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (anti-HCV), treponema pallidum antibody (anti-TP) and human immunodeficiency virus antibody (anti-HIV) at Zhongshan Ophthalmic Center of Sun Yat-sen University from January 2017 to December 2023. The positivity rates of these markers were recorded and analyzed. Results: A total of 253246 patients were included in the study, with positivity rates for HBsAg, anti-HCV, anti-TP, and anti-HIV at 9.00%, 0.45%, 1.55% and 0.13%, respectively. Among these, 686 patients tested positive for two or more markers, with the highest co-positivity observed for HBsAg and anti-HCV (57.29%), followed by anti-HIV and anti-TP (15.74%). The positivity rate of HBsAg showed a yearly decline, while the rates for anti-HCV, anti-HIV, and anti-TP remained relatively stable from 2017 to 2023. Males had significantly higher positivity rates for HBsAg, anti-HCV, anti-TP, and anti-HIV compared to females (P < 0.001). Significant differences in positivity rates for these markers were also observed across different age groups (P < 0.001). In patients with positive HBsAg, anti-HCV, and anti-TP, the proportion of cases with lens diseases were the highest, at 36.72%, 39.12%, and 46.97%, respectively. Vitreoretinal diseases followed, with proportions of 22.52%, 19.65%, and 19.69%, respectively. Among patients with positive anti-HIV, the proportion of cases with vitreoretinal diseases was the highest, at 42.99%, followed by lens diseases at 26.17%, and uveitis at 8.72%. Conclusions: This study reveals the infection status of four blood-borne pathogens in ophthalmology patients and the distribution of infected patients across different eye diseases, which is significant for assessing the risks of ophthalmic surgery and formulating infection control measures.

Objective: To evaluate the calcification level of retinoblastoma (RB) lesions using image post-processing system software, such as that for computed tomography (CT) noncontrast scanning and three-dimensional reconstruction. Additionally, this study aimed to explore the relationship between retinoblastoma (RB) and patient gender (male/female) , as well as the correlation among ocular (left/right), age, and radiographic stage (e.g., international intraocular RB stage).  Methods: The study enrolled 108 patients (127 eyes) with tumors confirmed by both surgical pathology and clinical diagnosis. These patients received treatment at the Orbital Disease and Ocular Oncology Department of Zhongshan Ophthalmic Center, Sun Yat-sen University (ZOC, SYSU) from May 2022 to December 2024. CT reconstruction and workstation segmentation techniques were used to delineate the eyeball, tumour, and calcification. A quantitative volumetric analysis method was applied, and statistical processing was conducted using R language (version 4.2.1). Comparisions were made across different genders (male/female), eye segmentation (left/right), age stratifications, and imaging stages. The t-test was applied to analyze the highest CT value, calcified regional volume (CRV), tumor volume (TV), eyeball volume (EV), CRV/EV ratio, TV/EV ratio, and CRV/TV ratio in these tumor patients. Results: There was no significant differences in CT value, CRV, TV,  CRV/EV ratio, TV/EV ratio, and CRV/TV ratio among patients with different eye sides, genders and age groups (P>0.05). Only EV showed statistical significant across different age groups. Statistically significant changes were observed in CRV, TV, CRV/EV ratio, TV/EV ratio , and CRV/TV ratio with respect to both intraocular stage (including intraocular stage, glaucoma stage, extraocular stage) and lens position changes (inculding position changes, morphological position density changes, no change groups) (P< 0.05), No other statistically significant differences were found (P>0.05). Conclusions: In this group of tumor patients, the level of calcification deposition gradually increased as the disease progressed through the intraocular stage, glaucoma stage, and extraocular stage. Lens positional changes were associated with a gradual increase in the degree of calcification in patients with retinoblastoma (RB) as the disease advanced.

Objective: To investigate the utilization of environmentally-sustainable reagents in ophthalmic tissue pathology techniques. Methods: We prospectively collected 190 surgical specimens submitted to the pathology department of Zhongshan Ophthalmic Center between June 2023 and March 2024. Each specimen was divided into two sets, one treated with environmentally-sustainable reagents and the other with conventional reagents for fixation, dehydration, clearing, infiltration, staining, and mounting. The quality of histological sections from both groups was evaluated and compared. Results: Compared to the conventional reagent group, environmentally-sustainable reagent group showed good dehydration performance, moderately soft and hard tissue sections with intact cut surfaces and no cracks. H&E staining sections prepared with environmentally-sustainable reagents exhibited clear nuclear structures, distinct nuclear-cytoplasmic contrast, and clean backgrounds. The excellent section rates were 97.9% and 98.4% for the two, respectively. There was no significant difference in section quality between the two groups (Z = –0.645, P = 0.519). Tissue antigenicity was well-preserved during immunohistochemical procedures, with strong positive signals and accurate localization without background staining. Conclusions: The use of environmentally-sustainable reagents as a replacement for conventional reagents in the dehydration and staining of ophthalmic tissue yields satisfactory results, meeting the daily requirements for routine histological sectioning and staining. The entire process is xylene-free, environmentally-sustainable, cost-effective and worth being applied widely.

Objective: To investigate the current status and identify the influencing factors regarding the knowledge, attitudes, and practices related to dry eye disease (DED) among patients. This study aims to provide a solid foundation for the development of targeted clinical interventions. Methods: With convenience sampling, patients diagnosed with DED were selected at the Dry Eye and Ocular Surface Disease Clinic of Zhongshan Ophthalmic Center from January to March 2025 as study subjects. The survey tools consisted of a general information questionnaire, the Chinese Dry Eye Questionnaire, and the Knowledge, Attitudes, and Practices (KAP) Questionnaire for DED patients. The KAP questionnaire was structured into three dimensions: knowledge (16 items), attitudes (7 items), and practices (9 items), making a total of 32 items. Univariate analysis and multiple linear regression were employed to identify influencing factors. Results: A total of 325 valid questionnaires were collected. Among the 325 DED patients, the average KAP score was 62.89±9.00, and the standardized score was 78.61±11.25, indicating a moderate level. In the knowledge dimension, the average score was 9.89±4.88 and 134 patients (41.2%) had poor scores. The attitudes dimension showed a relatively high level, with a total mean score of 26.92±2.24 and a standardized score of 96.16±8.03, reflecting that the patients generally held positive attitudes towards the prevention and treatment of DED. For the practices dimension, the total mean score was 26.06±5.43, and the standardized score was 72.41±15.09, indicating a moderate level of behaviorial practices. Univariate analysis revealed significant differences in KAP scores among patients with different ages, education levels, monthly household income per capita, frequencies of electronic device use, and whether they actively sought disease-related knowledge (P<0.05). Further, age, education level, and proactive information-seeking behavior were identified as significant influencing factors for KAP scores (P<0.05). Conclusions: The KAP level of DED patients is moderate. Their disease knowlege is fragmented, while they exhibit positive attitudes toward prevention and treatment. However, their behavioral practices are subptimal and are influenced by multiple factors. Therefore, it is essential to develop tailored and personalized health education programs to enhance the KAP level of DED patients.

Objective: To investigate the prevalence and distribution characteristics of fundus diseases among the elderly population aged 60 and above in Mangxin Town, Yengisar County, Kashgar Prefecture, Xinjiang, and to analyze the epidemiological status of fundus diseases in this region, thereby providing a scientific basis and data support for the development of fundus disease prevention and control strategies and the construction of a primary eye health service system in high-altitude areas of Western China. Methods: A cross-sectional study was conducted from May to June 2024 among the permanent residents aged 60 and above in Mangxin Town. Inclusion criteria were age ≥ 60 years, local residence for ≥ 6 months, and voluntary participation with signed informed consent. Data were collected through standardized ophthalmological examinations (including visual acuity testing, intraocular pressure measurement, slit-lamp microscopy, and fundus photography), structured questionnaire surveys, vital sign measurements, and laboratory tests. Diagnoses of fundus diseases were strictly based on domestic and international diagnostic criteria. Statistical analysis was performed using SPSS 24.0 to calculate the prevalence rates of various fundus diseases and their 95% confidence intervals. Results: A total of 1,310 elderly individuals were included, with a response rate of 76.76%. Among them, 669 (51.1%) were male and 641 (48.9%) were female, with a mean age of 68.4 ± 6.6 years. The overall prevalence of fundus diseases was 16.1% (95% CI: 14.2–18.0). The prevalence rates of specific fundus diseases were as follows: age-related macular degeneration, 5.9% (77 cases); optic atrophy, 2.8% (36 cases); epiretinal membrane, 2.3% (30 cases); diabetic retinopathy, 1.8% (23 cases); other macular diseases, 1.07% (14 cases); and hypertensive retinopathy, 0.99% (13 cases). Other fundus diseases, including high myopia-related fundus changes, retinitis pigmentosa, macular hole, vasculitis, and retinal hemorrhage, each had a prevalence of less than 0.38%. Among diabetic patients, the prevalence of diabetic retinopathy was 20.8%, which is consistent with previous domestic and international studies. Conclusions: The prevalence of fundus diseases among the elderly in Mangxin Town, Xinjiang, is relatively high, with age-related macular degeneration being the most common type. This study fills a gap in the epidemiological data on fundus diseases in high-altitude regions of Western China. The findings highlight the need to establish a targeted stratified screening and prevention system, strengthen fundus health management in the elderly, and promote a screening model combining portable fundus photography with telemedicine to improve the accessibility and quality of primary eye health services.

Objective: To evaluate the clinical efficacy and safety of microscopic radiofrequency ablation in treating of distichiasis and aberrant lashes. Methods: We performed a retrospective analysis on 18 patients with trichiasis (distichiasis and aberrant lashes) who underwent microscopic radiofrequency ablation treatment. All patients were followed up for a minimum of 3 months after the operation. The outcome measures included trichiasis clearance rate, the number of treatment sessions  needed to achieve success, complications, and patient satisfaction. Spearman rank correlation analysis was used to evaluate the correlation between the baseline characteristics of patients and the number of treatment sessions. Results: The study included 18 patients with a total of 30 eyes. Immediately after the operation,  the trichiasis clearance rate achieved through microscopic radiofrequency ablation was 100%. Among the eyes, 5 eyes (16.7%) were  successful treatment after just one session, 11 eyes (36.7%) required 2 treatment sessions, 13 eyes (43.3%) needed 3 treatment sessions, and 1 eye (3.3%) required more than 3 treatment sessions to achieve success. The major complications included dry eye in 13 cases (43.3%) and eyelid margin inflammation in 1 case (3.3%). Notably, no severe complications such as eyelid deformity or scarring were observed. According to the patient satisfaction survey, 16 cases (88.9%) reported being very satisfied, and 2 cases (11.1%) were basically satisfied, resulting in an overall satisfaction rate of 100%. The correlation analysis indicated that the number of trichiatic eyelashes was significantly positively correlated with the number of treatment sessions (r_s=0.672, P=0.002). Conclusions: Microscopic radiofrequency ablation for distichiasis and aberrant lashes treatment boasts serveral advantages, including precise localization, effective destruction of hair follicle, short treatment duration, minimal trauma, rapid recovery, and high safety. With a high level of  patient satisfaction, it serves as an effective treatment method for distichiasis and aberrant lashes.

年龄相关性黄斑变性（age-related macular degeneration, AMD）是一种与氧化应激及多基因调控异常密切相关的视网膜黄斑区域进行性退化性疾病。由于黄斑区缺乏血管，因此对氧气的高度依赖使其特别容易受到氧化应激的影响。氧化应激反应影响视网膜色素上皮细胞（retinal pigment epithelium, RPE）功能，导致RPE细胞代谢异常、RPE细胞凋亡与损伤；影响脉络膜血管功能，表现为新生血管异常和血管内皮细胞功能障碍；过度激活补体系统，使炎症细胞浸润与炎症因子释放引发炎症；这三者构成了AMD的发病机制之一。文章列举了抗氧化酶基因家族（超氧化物歧化酶、过氧化氢酶、谷胱甘肽过氧化物酶）、炎症相关基因（补体系统相关基因和细胞因子相关基因）和其他相关基因（血管内皮生长因子、血红素加氧酶-1、载脂蛋白E、铁死亡相关基因、年龄相关性黄斑病变易感因子2基因）的异常表达与AMD产生的关联性，并阐述了基因编辑技术纠正氧化应激相关基因缺陷和基于氧化应激基因靶点的药物治疗手段，以期为AMD的防治提供思路。

Age-related macular degeneration (AMD) is a retinal degenerative disease closely associated with oxidative stress and dysregulation of polygenic mechanisms. Due to the absence of blood vessels in the macular region, its high dependence on oxygen renders it particularly susceptible to oxidative stress. Oxidative stress impairs the function of retinal pigment epithelium (RPE) cells, leading to metabolic dysregulation, apoptosis, and cellular damage. It also disrupts choroidal vascular function, characterized by abnormal neovascularization and endothelial dysfunction. Moreover, excessive activation of the complement system promotes inflammatory cell infiltration and the release of pro-inflammatory cytokines. Collectively, these processes constitute one of the key pathogenic mechanisms underlying AMD. This paper highlights the pathogenic associations between AMD progression and dysregulated expression in antioxidant enzyme genes (e.g., superoxide dismutase, catalase, glutathione peroxidase), inflammation-related genes (e.g., complement and cytokine-related genes), and other relevant genes (e.g., vascular endothelial growth factor, heme oxygenase-1, apolipoprotein E, ferroptosis-related genes, age-related maculopathy susceptibility 2 gene). Potential therapeutic strategies, including gene editing to correct oxidative stress-related genetic defects and pharmacological interventions targeting oxidative stress-associated genes, are also elaborated, aiming to provide new insights into AMD prevention and treatment.

脂质运载蛋白2（LCN2/NGAL）是一种多效性分泌糖蛋白，通过调控铁代谢、炎症反应及细胞死亡（铁死亡、凋亡）等机制，广泛参与眼科疾病的病理进程。生理状态下，LCN2在角膜上皮、视网膜神经节细胞层等部位低表达；病理条件下，其表达显著上调且功能呈现高度背景依赖性。在各类眼科疾病（如干眼症、角膜疾病、葡萄膜炎、青光眼、视网膜疾病等）中，既可表现为促炎促凋亡的致病因子，亦能发挥抗炎保护作用。靶向调控LCN2表达或其下游通路可能为眼科疾病治疗提供新策略。

Lipocalin-2 (LCN2/NGAL) is a multifunctional secretory glycoprotein that plays a critical role in the pathogenesis of ophthalmic diseases by regulating iron metabolism, inflammatory responses, and cell death pathways (ferroptosis, apoptosis). Under physiological conditions, LCN2 is expressed at low levels in tissues such as the corneal epithelium and retinal ganglion cell layer. However, its expression is significantly upregulated under pathological conditions, exhibiting highly context-dependent functionality. In major ophthalmic diseases—including dry eye disease, corneal disorders, uveitis, glaucoma, and retinal diseases—LCN2 can act either as a pro-inflammatory and pro-apoptotic pathogenic factor or as an anti-inflammatory protective agent. Targeted modulation of LCN2 expression or its downstream pathways may offer novel therapeutic strategies for ocular diseases.

全眼球移植（Whole eye transplantation, WET）是治疗因外伤、肿瘤等导致眼球不可逆损伤及永久性失明的潜在终极手段。其核心不仅在于实现眼球解剖结构的完整移植，更关键的是实现功能性视觉恢复，关键挑战包括优化手术策略重建眼球血液循环，实现供体视神经与受体视觉中枢的神经连接，建立精准有效的免疫调控策略以平衡移植耐受与感染风险。本文系统梳理了WET领域的研究进展与发展挑战。早期研究以变温动物模型为主，这些模型在一定程度上证实了视觉通路在眼球移植后仍具有一定的可塑性，但由于其眼球结构与人类存在显著解剖差异，且实验设计中未涉及精细的血管与神经吻合，因而临床转化价值有限。随着显微血管技术的发展，哺乳动物模型及人眼球移植的初步探索在显微外科血管吻合技术方面取得重要突破，实现了移植眼球视网膜血液灌注的短期重建，但仍面临视神经再生障碍和功能维持难题。当前的研究瓶颈主要集中在三个方面：血液循环重建技术优化、神经轴突精准再生及免疫微环境调控。建立与人类接近的标准化非人灵长类动物模型，并开展系统性的实验研究，将为克服现有技术障碍、推动WET走向临床提供至关重要的实验依据和新思路。

Whole eye transplantation (WET) is a potential definitive treatment for irreversible ocular damage and permanent blindness caused by conditions like trauma or tumors. The success of WET depends not only on the complete anatomical restoration of the transplanted eye but, more critically, on the recovery of functional vision. Key challenges in this field include optimizing surgical strategies to re-establish ocular blood circulation, achieving functional neural integration between the donor optic nerve and the recipient's visual centers, and developing precise and effective immunomodulation strategies to strike a balance transplant tolerance and infection risk. This review provides a systematic review of the research progress and developmental challenges in the field of WET. Early studies primarily utilized poikilothermic animal models, which demonstrated a certain degree of plasticity in the visual pathway following transplantation. However, due to significant anatomical differences compared to humans and the lack of sophisticated vascular and neural anastomosis in experimental designs, their clinical translatability of these studies remained constrained. With the progress in microvascular techniques, preliminary explorations in mammalian models and human eye transplantation have achieved significant breakthroughs in microsurgical vascular anastomosis, enabling the short-term reestablishment of retinal blood perfusion in transplanted eyes. Nonetheless, perisitent obstacles include inadequate optic nerve regeneration and poor long-term functional maintenance. Currently, research bottlenecks mainly focus on three aspects: optimizing surgical techniques for blood circulation reconstruction, precisely regenerating nerve axons, and regulating the immune microenvironment. Establishing standardized non-human primate models that closely mimic humans and conducting systematic experimental studies will furnish crucial evidence and novel insights to overcome existing technical hurdles and propel WET toward clinical application.
