目的：了解湿性老年性黄斑变性(age-related macular degeneration,AMD)患者自我感受负担(self-perceived burden,SPB)现状及其影响因素。方法：采用方便抽样法选取2021年1月至11月在中山大学中山眼科中心就诊的204例湿性AMD患者为研究对象，采用一般资料调查表、SPB量表、家庭支持自评量表、医学应对问卷对其进行测评。结果：患者SPB得分是(21.98±6.68)分，总体属于轻度SPB。湿性AMD患者的SPB水平与家庭支出(r=?0.326, P<0.001)和面对应对(r=?0.365, P<0.001)呈负相关，与回避(r=0.456, P<0.001)及屈服(r=0.310, P<0.001)应对方式呈正相关性。多重线性回归显示，独居、高龄、自费、双眼患病及采用回避应对的患者的SPB更高，而高文化水平、高家庭支持的患者SPB较轻。结论：湿性AMD患者有轻度SPB，但仍存在改善空间，医护工作者在工作中应重点关注高龄、文化程度低、家庭收入低、自费、独居、双眼患病及低视力的患者，及时进行心理疏导，减轻患者的SPB水平。
Objective: To understand the current status and influencing factors of self-preceived burden (SPB) in patients with wet age-related macular degeneration (AMD). Methods: 204 patiens with wet AMD who were treated in Zhongshan Ophthalmic Center, Sun Yat-sen University from January to November 2021 were enrolled as the study subjects with convenience sampling method. A general information questionnaire, SPB scale, family support self-assessment scale, and medical coping questionnaire were collected from the subjects for assessment. Results: The patient’s SPB score was 21.98±6.68, which is generally mild SPB. The SPB level of patients with wet AMD was negatively correlated with family support (r=-0.326, P<0.001) and coping (r=?0.365, P<0.001), and were positively correlated with avoidance (r= 0.456,P<0.001), and surrender (r=0.310, P<0.001) coping style. Multiple linear regression showed that the patients who lived alone, were elder and self-funded, had binoclur diseases and used avoidance coping, had higher SPB. While the patients with high education and family support had lower SPB. Conclusions: It is still needed to pay attention to the patients with AMD having mild SPB. Medical workers should focus on patients with elder age, low education level, low family income, self-funded, living alone, binocular disease and low vision in their work, and provide timely psychological counseling to reduce the SPB level of patients.
目的：探讨并分析青光眼患者积极度的潜在剖面及其关联因素，为临床制订精准干预策略提供实证依据。方法：采用横断面调查法，选取2024年7—10月在中山大学中山眼科中心就诊的202例青光眼患者 为研究对象。研究工具包括一般资料调查表、患者积极度量表、一般自我效能量表及领悟社会支持量 表，应用Mplus 8.3软件进行潜在剖面分析，并采用多因素回归模型探索不同类别患者的社会人口学、疾病相关及心理社会相关因素。 结果：青光眼患者积极度分为两个潜在剖面:“高激活度-主动适应型” (33.66%)、“低激活度-应对依赖型”(66.34%)。多因素分析结果显示，居住地为城市、月收入较高、晚期视野缺损、手术次数≥3次、一般自我效能较高以及社会支持水平较好的患者，更可能归属于“高激活 度-主动适应型” (P<0.05)。结论：青光眼患者积极度整体处于中等偏下水平，以“低激活度–应对依赖 型”为主导。提示医护人员应重视青光眼患者积极度的评估，并基于潜在类别及相关因素，从增强自 我效能、拓展社会支持、加强健康教育等方面入手，为不同类别患者制订个性化、有针对性的干预方 案，从而有效提升青光眼患者的积极度水平及其疾病自我管理能力，以期改善长期治疗依从性与生活质量。
Objective: To explore and analyze the latent profiles of glaucoma patient activation and their associated factors, providing empirical evidence for developing precise clinical intervention strategies. Methods: A cross-sectional survey was conducted, involving 202 glaucoma patients recruited from Zhongshan Ophthalmic Center, Sun Yat-sen University, between July and October 2024. The study utilized the General Information Questionnaire, the Patient Activation Measure, the General Self-Efffcacy Scale, and the Perceived Social Support Scale. Latent proffle analysis was performed using Mplus 8.3 software to identify distinct profiles of patient activation, and a multivariate regression model was employed to explore the sociodemographic, disease-related, and psychosocial factors associated with different proffles. Results: TTe patient activation in glaucoma patients was categorized into two latent proffles: "High Activation–Active Adaptation Type" (33.66%) and "Low Activation–Coping Dependent Type" (66.34%). Multivariate analysis revealed that patients who were urban residents, had higher monthly income, presented with advanced visual field defects, underwent three or more surgeries, reported higher general self-efffcacy, and had better perceived social support were more likely to belong to the "High Activation–Active Adaptation Type" (P<0.05). Conclusions: TTe overall level of patient activation in glaucoma patients is moderate to low, predominantly characterized by the "Low Activation–Coping Dependent Type." TTis suggests that healthcare professionals should prioritize the assessment of patient activation in glaucoma care. Based on the identiffed latent proffles and their associated factors, personalized and targeted intervention strategies—such as enhancing self-efffcacy, expanding social support, and strengthening health education—should be developed for different patient subtypes. TTese efforts are essential to effectively improve patient activation levels and disease self-management capabilities, thereby enhancing long-term treatment adherence and quality of life.
目的：识别新生血管性年龄相关性黄斑变性（neovascular age-related macular degeneration,NVAMD）患者接受抗血管内皮生长因子（vascular endothelial growth factor,VEGF）药物治疗后出现的黄斑萎缩事件，并评估其治疗前的眼部解剖结构变化。方法：回顾 2014 全年期间由采用抗 VEGF 药物治疗的所有 NVAMD 患者，这些患者的随访时间均超过 12 个月，并评估了从首次治疗（通常在 2014 年前）至 2018 年 6 月最后一次随访期间的所有谱域光学相干断层扫描（spectral domain-optical coherence tomography, SD-OCT）图像。结果：在既定的研究流程中，共识别出 278 例 NVAMD 患者的 342 眼，其中 47 眼发生了黄斑萎缩。从治疗开始到黄斑萎缩出现的中位时间为 29.6 个月（四分位距：17.7-43.4）。在发生萎缩的区域中，发现了三种黄斑结构改变（部分眼睛存在不止一种改变）：在 25 眼中观察到血管化色素上皮脱离（pigment epithelial detachment,PED）的塌陷和脉络膜新生血管（choroidal neovascularization，CNV）的消退；在 15 眼中观察到视网膜下高反射物质和(或)视网膜下纤维化的形成；在 13 眼中观察到黄斑萎缩与大玻璃膜疣及色素改变相关联，呈现出通常称为地图状萎缩的典型模式。结论：这些数据表明，在某些情况下，CNV 可能补偿脉络膜的缺血状态，而 CNV 的消退则可能使 RPE 细胞和光感受器暴露于缺血性损伤和萎缩的风险之中。
Background/Aims: To identify incident macular atrophy and evaluate antecedent anatomic alterations in eyes with neovascular age-related macular degeneration (NVAMD) that were treated with anti-vascular endothelial growth factor (anti-VEGF) agents. Methods: All patients treated with anti-VEGF agents for NVAMD by one of the authors during the 2014 calendar year who had follow up ≥ 12 months had evaluation of all SD-OCT scans from first treatment (usually prior to 2014) to last follow up through June 2018. Results: The ascertainment procedure identified 342 eyes of 278 patients with NVAMD among which 47 developed macular atrophy. The median time from treatment initiation to development of macular atrophy was 29.6 (interquartile range, 17.7 - 43.4) months. Three macular alterations were identified in areas that developed atrophy (some eyes had more than one); collapse of a vascularized pigment epithelial detachment (PED) and regression of choroidal neovascularization (CNV) in 25 eyes, development of subretinal hyper-reflective material and/or subretinal fibrosis in 15 eyes, or atrophy occurring in association with large drusen and pigmentary changes resulting in an arc of atrophy in a pattern typically referred to as geographic atrophy in 13 eyes. Conclusions: These data suggest that in some instances CNV may compensate for choroidal ischemia and the loss of CNV may expose retinal pigmented epithelial cells and photoreceptors to ischemic damage and atrophy.
目的：了解干眼患者相关知识、管理态度及防治行为的现状及影响因素，为临床制定针对性的干预措施提供依据。方法：采用便利抽样法，选取2025年1—3月在中山大学中山眼科中心干眼与眼表疾病门诊就诊的患者为研究对象。调查工具为一般资料调查表、中国干眼问卷及干眼患者知信行问卷。知信行问卷包括知识（16个条目）、态度（7个条目）、行为（9个条目） 3个维度，共32个条目。使用单因素分析及多元线性回归分析确定影响因素。 结果：有效回收调查问卷325份，325例干眼患者的知信行问卷平均得分为（62.89±9.00）分；标准分为（78.61±11.25）分，处于中等水平。其中知识维度平均得分为（9.89±4.88）分，134例（41.2%）处于较差水平；态度维度得分较高，总均分为（26.92±2.24）分，标准分（96.16±8.03）分，处于较高水平；行为维度总均分为（26.06±5.43）分，标准分（72.41±15.09）分，处于中等水平。单因素分析结果显示，不同年龄、文化程度、家庭人均月收入、是否经常使用电子设备、是否主动查询疾病知识的干眼患者，其知信行得分比较差异有统计学意义（P<0.05）。年龄、文化程度、是否主动查询疾病知识是干眼患者知信行得分的影响因素（P<0.05）。 结论：干眼患者知信行水平处于中等，表现为疾病知识掌握片面、防治态度较积极但行为水平有待提高，且受多因素影响，应制订精准、个性化健康教育内容，以提高干眼患者的知信行水平。
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.
目的：分析鼻内镜下泪囊鼻腔吻合术手术疗效的影响因素。方法：纳入2021年1月—2023年7月在成都中医药大学附属医院眼科行鼻内镜下泪囊鼻腔吻合术(endoscopic dacryocystorhinostomy, En-DCR)治疗的单眼慢性泪囊炎患者90例(90只眼)。所有患者均进行泪道CT造影检查及鼻内镜下泪囊鼻腔吻合术，术后随访6个月，评估手术疗效，分析手术疗效的影响因素。结果：本研究显示，慢性泪囊炎患者中女性占比为90%，平均年龄为(49.97±13.10)岁。单因素分析结果显示，术中是否置入引流管、下鼻甲肥厚与EnDCR手术疗效有关(P < 0.05)。Logistic多因素回归分析结果显示，下鼻甲肥厚为En-DCR手术疗效的危险因素(P < 0.05)。结论：慢性泪囊炎多发生于中老年女性。下鼻甲肥厚为En-DCR手术疗效的危险因素。
Objective: To analyze the influencing factors for effect of endoscopic dacryocystorhinostomy. Methods: A total of 90 patients (90 eyes) diagnosed with unilateral chronic dacryocystitis undergoing endoscopic dacryocystorhinostomy in the Department of ophthalmology, Hospital of Chengdu University of Traditional Chinese Medicine from January 2021 to July 2023 were included. All patients underwent lacrimal duct CT imaging and endoscopic dacryocystorhinostomy, and were followed up for 6 months to evaluate the efficacy of surgery. Results: This study showed that 90% of patients with chronic dacryocystitis were female, and the average age of patients was (49.97±13.096) years. The results of univariate analysis showed that there was a correlation between intraoperative drainage tube placement and inferior turbinate hypertrophy and the efficacy of En-DCR (P < 0.05). The results of Logistic regression analysis showed that inferior turbinate hypertrophy was a risk factor for the efficacy of En-DCR (P < 0.05). Conclusions: Dacryocystitis mostly occurs in middle-aged and elderly women. Inferior turbinate hypertrophy are the influencing factors of surgical effect. Chronic dacryocystitis mostly occurs in middle-aged and elderly women. Inferior turbinate hypertrophy is a risk factor affecting the curative effect of En-DCR surgery.
Diabetic retinopathy (DR), a major micro-vascular complication of diabetes, has emerged as a leading cause of visual impairment and blindness among adults worldwide. However, aside from pathological damage, the traditional laser and multi-needle operation treatments required for more advanced disease can cause further damage to the visual field and increase the operation risk. Therefore, the development of new therapeutic strategies for the prevention and treatment of DR is essential. Some emerging evidence now indicates that pigment epithelium-derived factor (PEDF), a multifunctional protein, can target multiple pathways to exert neurotropic, neuroprotective, anti-angiogenic, anti-vasopermeability, anti-inflammation, anti-thrombogenic, and anti-oxidative effects against DR. This review addresses the functions of PEDF in different pathways that could lead to potential therapeutics for the treatment of DR.

目的：研究准分子激光原位角膜磨镶术(laser in situkeratomileusis，LASIK)前后角膜滞后量(corneal hysteresis，CH)和角膜阻力因子(corneal resistance factor，CRF)变化量，对其相关因素进行多元线性回归分析。方法：前瞻性研究。纳入行LASIK手术的近视眼及近视散光患者70眼(38例)，术前与术后6个月各项参数分别由眼反应分析仪(ocular response analyzer，ORA)、非接触眼压仪、超声角膜测厚仪及Pentacam眼前节分析仪测量。分析LASIK手术前后△CH，△CRF与术前、手术设计等参数的相关性，并对相关参数进行多元线性回归分析。结果：手术前后CH分别为(10.05±1.36)，(8.15±0.90) mmHg(1 mmHg=0.133 kPa)，CRF分别为(9.91±1.38)，(6.92±0.88) mmHg，差异均有统计学意义(P<0.01)；△CH与△CRF分别为(1.90±1.15)，(2.99±1.23) mmHg。△CH与术前CH，CRF，眼压(intraocular pressure，IOP)，预计切削深度(ablative depth，AD)以及AD/CCT呈正相关；△CRF与术前CH，CRF，IOP，AD，AD/CCT，术前等值球镜(spherical equivalent，SE)以及预计基质床厚度(residual stromal bed’s thickness，RSBT)有相关性。采用多元线性回归对LASIK手术前后△CH，△CRF与术前、手术设计等各相关参数进行分析，回归方程为：△CH=?6.182+0.658CH术前+8.421AD/CCT (R2=0.639，P<0.01)，△CRF=?0.007+0.725CRF术前?0.014RSBT (R2=0.689，P<0.01)。结论：LASIK术前后CH与预计AD和角膜厚度比值密切相关，CRF变化量与预计角膜RSBT密切相关，在设计手术时应慎重考虑预计AD与预计RSBT。
Objective: To discuss the change of corneal hysteresis and corneal resistance factor before and after laser in situkeratomileusis (LASIK), and to analyze their related factors by multivariate linear regression. Methods: In this prospective study, 70 eyes (38 patients) with myopia and myopic astigmatism undergoing LASIK were included. Related factors were measured preoperatively and at 6 months postoperatively by ocular response analyzer, noncontact tonometer (NCT), ultrasonic pachymeter, and Pentacam system. TTe correlation was analyzed between △CH, △CRF and preoperative and operative design’s parameters, and correlative factors analyze. △CH and △CRF were analyzed by the multiple linear regression. Results: CH before and after LASIK were (10.05±1.36) and (8.15±0.90) mmHg, and CRF before and affer LASIK were (9.91±1.38) and (6.92±0.88) mmHg. TTere was signiffcant difference between preoperative and postoperative CH and CRF (P<0.01). △CH and △CRF were (1.90±1.15) and (2.99±1.23) mmHg. Preoperative CH, CRF, intraocular pressure (IOP), ablative depth (AD) and AD/CCT were positive correlated with △CH. Preoperative CH, CRF, IOP, AD, AD/CCT, preoperative spherical equivalent (SE) and predicted residual stromal bed’s thickness (RSBT) were correlated with △CRF. TTe regression equation of △CH and △CRF and influencing factors were △CH =?6.182 + 0.658CHpreoperative + 8.421AD/CCT (R2 =0.639, P<0.01), △CRF =?0.007 + 0.725CRFpreoperative ? 0.014RSBT (R2 =0.689, P<0.01). Conclusion: The change of CH before and after LASIK is correlative with AD/CCT. The change of CRF before and after LASIK is correlative with predicted residual stromal bed’s thickness. Ablative depth and predicted residual stromal bed’s thickness should be considered carefully during the surgical design.
