儿童白内障是全球范围内可治疗儿童盲症的主要原因之一。对于这些患儿而言，手术是恢复或保护视力的主要方法。然而，手术后的并发症，特别是青光眼相关不良事件(glaucoma-related adverse events, GRAEs)，常常成为导致儿童二次致盲的主要原因，这引起了眼科医疗领域的广泛关注。文章综述了儿童Ⅱ期人工晶状体植入术后GRAEs的影响因素，包括手术设计、眼部解剖特征、其他眼部发育异常和全身疾病等。手术设计中是否植入人工晶状体(intraocular lens，IOL)以及植入的时机和位置都对GRAEs的发生有显著影响。此外，眼部解剖特征如角膜直径、眼轴长度、前房深度、中央角膜厚度和术前晶状体厚度等，也是影响GRAEs发生的重要因素。同时，其他眼部发育异常和全身疾病，如先天性无虹膜、先天性风疹综合征等，也会增加儿童白内障术后青光眼的发生率。文章还总结了预测GRAEs的方法，并推荐使用Cox回归模型建立预测模型。这种模型可以有效地预测儿童Ⅱ期IOL植入术后在特定时间段内发展为GRAEs的概率，从而为早期识别GRAEs高危儿童提供了重要的借鉴。通过对GRAEs影响因素的深入分析和预测模型的建立，文章旨在帮助眼科医生更好地理解GRAEs的发生机制，并在手术前对患儿进行风险评估，从而选择最佳的手术方案和预防措施。这对于改善患儿的术后恢复、减少并发症、保护视功能具有重要的临床意义。
Pediatric cataract is one of the leading causes of treatable childhood blindness worldwide. For these children, surgery is the primary method to restore or preserve vision. However, postoperative complications, particularly glaucoma-related adverse events (GRAEs), often become the main reason for secondary blindness in children, attracting widespread concern in the field of ophthalmology. This study reviews the impact factors of glaucoma-related adverse events after secondary intraocular lens (IOL) implantation in children, including surgical design, ocular anatomical characteristics, other ocular developmental abnormalities, and systemic diseases. Whether to implant an IOL in the surgical design and the timing and positioning of the implantation have a significant impact on the occurrence of GRAEs. In addition, ocular anatomical characteristics, such as corneal diameter, axial length, anterior chamber depth, central corneal thickness, and preoperative lens thickness, are also important factors affecting the occurrence of GRAEs. At the same time, other ocular developmental abnormalities and systemic diseases, such as congenital aniridia and congenital rubella syndrome, also increase the incidence of glaucoma after pediatric cataract surgery. The article also summarizes methods for predicting GRAEs and recommends using the Cox regression model to establish a predictive model. This model can effectively predict the probability of children developing GRAEs after secondary IOL implantation within a specific time period, providing an important reference for the early identification of high-risk children for GRAEs. Through in-depth analysis of the impact factors of GRAEs and the establishment of predictive models, the article aims to help ophthalmologists better understand the mechanisms of GRAEs and assess the risks of children before surgery, thereby selecting the best surgical plan and preventive measures. This is of great clinical significance for improving postoperative recovery in children, reducing complications, and protecting visual function.
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.

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 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.
