目的：探讨青光眼日间手术患者的自我管理行为现状及影响因素分析。方法：采用便利抽样法选取2021年9月—2022年5月于广州市某三级甲等眼科专科医院就诊的223例青光眼日间手术患者。采用一般资料调查表、青光眼自我管理行为量表、慢性疾病自我效能量表和青光眼知识学习问卷进行问卷调查。结果：青光眼日间手术患者的自我管理行为得分为(54.03±6.95)分，其中生活调整维度得分最低。慢性病自我效能与自我管理行为呈正相关(r=0.368, P<0.001)。疾病知识与自我管理行为无显著相关性(r=0.077, P=0.252)。多因素线性回归分析结果显示，患者的文化程度(P<0.001)和自我效能(P=0.028)是自我管理行为的影响因素，可解释自我管理行为总变异的12.4%。结论：青光眼日间手术患者具有良好的自我管理行为，较低的自我效能和文化程度是自我管理行为的危险因素，因此应优先提高患者的自我效能，并提供个性化教育。

Objective: To determine self-management and its association with self-efficacy and knowledge among glaucoma patients undergoing day surgery. Methods: A total of 223 glaucoma patients were recruited from September 2021 to May 2022and they were investigated with the Glaucoma Self Management Questionnaire (GSMQ), The Self- Efficacy in Chronic Disease Scale (SECD-6), and the glaucoma knowledge questionnaire. Results: Of the 223 study participants, the study population had a total GSMQ score of 54.03±6.95 with the lowest score found in the life adjustment dimension. The total SECD-6 score was showing a significantly positive correlation with the total GSMQ score(r =0.368, P <0.001). The total score of disease knowledge was without significant correlation with the total GSMQ score (r =0.077, P =0.252). Multivariate linear regression analysis showed that self-efficacy (P <0.001) and education level was independently associated with self-management(P =0.028). Conclusions: Glaucoma patients undergoing daytime surgery demonstrated good overall self-management, yet further improvement was required in terms of life adjustment. Low self-efficacy and educational level were identified as risk factors for self-management. Therefore, self-management programs should prioritize enhancing patients' self-efficacy and delivering individualized education.

息肉状脉络膜血管病变(polypoidal choroidal vasculopathy,PCV)是亚洲人群中常见的致盲性眼病，发生大出血并发症后严重危害视力且预后差。PCV大出血包括视网膜下出血(subretinal hemorrhage,SRH)和玻璃体积血(vitreous hemorrhage,VH)。SRH的危险因素包括较长病程、簇型PCV、息肉状病灶不消退、合并视网膜色素上皮脱离；其治疗方式包括抗血管内皮生长因子药物、光动力疗法、激光、玻璃体腔注气、眼内注射组织纤溶酶原激活剂、玻璃体切割术或联合治疗等方式，其中，黄斑中心凹是否受累和出血时间是影响治疗方式选择的主要因素。发病年龄较大、白细胞计数较高、天门氨酸转移酶和丙氨酸转氨酶的比值较高、活化部分凝血活酶时间较长、曾行光动力疗法、有玻璃体腔注药治疗史、SRH面积大、出现视网膜色素上皮脱离的PCV患者发生VH的风险高。浓厚的VH通常需行玻璃体切割术，其手术时机和手术方式的选择是临床关注的焦点。鉴于目前PCV大出血的危险因素尚不完全明确、治疗方面也尚未形成共识，需要开展相关临床研究，提供更多依据。

Polypoidal choroidal vasculopathy (PCV) is a common blinding disease in Asian populations. Massive hemorrhage complications secondary to PCV include subretinal hemorrhage (SRH) and vitreous hemorrhage (VH). The risk factors for SRH include a long duration, clustered PCV, non-regression of polyp lesions and presented with retinal pigment epithelial detachment. The treatments for SRH include anti-vascular endothelial growth factor drugs, photodynamic therapy, laser, vitreous pneumatic displacement, intravenously injected tissue plasminogen activator, vitrectomy and combination therapy. Whether macular fovea is involved and the time since bleeding onset are the main factors afecting the choice of treatment for SRH. Older age of onset, higher white blood cell count, higher aspartate amino transferase and alanine amino transferase ratio, longer activated partial thromboplastin time retinal pigment epithelium detachment, photodynamic therapy history, intravitreal injection history larger SRH area and presented with retinal pigment epithelial detachment were associated with higher risk of VH. PCV patients with massive VH should be treated with vitrectomy, while the timing and technique of operation should be paid atention to. At present, the risk factors of PCV massive bleeding are not completely clear, and its treatment methods are diverse, which requires a large number of studies to prove its effectiveness and establish expert diagnosis and treatment consensus.

糖尿病性黄斑水肿(diabetic macular edema, DME)是糖尿病最常见和最严重的并发症之一，也是中青年劳动人群常见的致盲原因。DME病理生理机制复杂，是多种因素相互作用的结果，控制这些危险因素是降低发病率的关键。DME是全身病相关性眼病，其发生与发展受众多危险因素的影响，但此前文献对其总结不足，本文从全身因素及眼部因素两个方面就DME的危险因素进行综述。全身危险因素主要包括血糖控制欠佳、糖尿病病程长、高血压、血脂代谢紊乱、肥胖、肾功能异常、妊娠状态、降糖药物使用、贫血、阻塞性睡眠呼吸暂停低通气综合征、遗传因素、吸烟、饮酒、高血钙、低血镁等；而其眼部危险因素主要包括白内障、青光眼及玻璃体切割术、全视网膜激光光凝术、合并视网膜静脉阻塞和相关细胞因子等。深入认识和理解这些危险因素，有助于更好地预防和早期治疗DME，同时为治疗糖尿病视网膜病变过程中控制DME进展提供指引和参考。但是，其中一部分因素还存在一定争议，更多的DME危险因素仍有待进一步探索，期望在不久的将来，更多基础和前瞻性临床研究为DME危险因素及治疗提供高质量的证据。

Diabetic macular edema (DME) is one of the most common and severe complications of diabetes, and it is a leading cause of blindness in the working-age population. The pathophysiology of DME is complex, resulting from the interplay of various factors. Controlling these risk factors is crucial in reducing the incidence of DME. As a systemic diseaserelated ocular condition, the onset and progression of DME are influenced by numerous risk factors. However, previous literature has provided insufficient summaries of these factors. This review aims to summarize the risk factors for DME from both systemic and ocular perspectives. The systemic risk factors primarily include poor glycemic control, prolonged duration of diabetes, hypertension, dyslipidemia, obesity, renal dysfunction, pregnancy, the use of hypoglycemic medications, anemia, obstructive sleep apnea-hypopnea syndrome, genetic factors, smoking, alcohol consumption, hypercalcemia, and hypomagnesemia. On the other hand, ocular risk factors include cataracts, glaucoma and vitrectomy, panretinal photocoagulation, coexisting retinal vein occlusion, and related cytokines. A deeper understanding of these risk factors will aid in the better prevention and early treatment of DME, while also providing guidance and reference for controlling the progression of DME during the treatment of diabetic retinopathy. However, some of these factors remain controversial, and additional DME risk factors still need to be explored. It is hoped that, in the near future, more 

foundational and prospective clinical studies will provide high-quality evidence on DME risk factors and treatments.

目的：探讨白内障人群角膜屈光力(corneal refractive power,CRP)的分布特点及与眼生物学参数的相关因素分析。方法：回顾性横断面研究福州眼科医院2019年3月至2022年7月就诊的40岁以上白内障人群共23035眼，使用OA-2000测量其眼轴(axial length,AL)、CRP、前房深度(anterior chamber depth,ACD)、晶状体厚度(lens thickness,LT)、角膜水平直径即白到白(white-to-white,WTW)、中央角膜厚度(central corneal thickness,CCT)。绘制各眼生物学参数及年龄Spearman相关性热力图，绘制CRP与AL、CRP与WTW散点拟合图。将CRP与上述参数及年龄进行Spearman相关性分析，分段数据的线性关系使用Pearson分析及线性回归分析。结果：白内障人群CRP为(44.36±1.52)D，在总体数据中CRP与AL为非线性相关；但在分段数据中存在线性相关：当AL≤25.06 mm，CRP与AL负线性相关(R² =0.397，P<0.001)；当AL>25.06 mm，CRP与AL正线性相关(R² =0.045，P<0.001)；无论AL长短，CRP与WTW、CCT均呈负相关。在总体数据中，CRP与WTW也存在非线性关系；但在分段数据中存在线性相关：当10.52 mm≤WTW≤12.46 mm，CRP与WTW负线性相关(R² =0.149，P<0.001)，并与AL、ACD、CCT呈负相关。结论：CRP与AL、WTW呈非线性相关，使用CRP优化计算人工晶状体(intraocular lens,IOL)屈光力时需适当考虑AL、WTW与CRP的相关性。

Objective: To investigate the distribution characteristics of corneal refractive power (CRP), and analyze the correlation between corneal refractive power and ocular biometric parameters in cataract patients. Methods: A retrospective cross-sectional study was conducted on 2,3035 eyes of cataract patients over 40 years old, who visited Fuzhou Eye Hospital during the period between March 2019 and July 2022. The subjects' examination results of axial length (AL), corneal refractive power (CRP), anterior chamber depth (ACD), lens thickness (LT), horizontal corneal diameter (WTW), central corneal thickness (CCT) were measured by OA-2000. Spearman correlation thermograms of bilological parameters and age for each eyes were worked out. The plot scatter fitting plots of CRP and AL, CRP and WTW were made. Spearman correlation analysis was made among CRP, above-mentioned parameters and age. Linear relationships of the segmented data were analyzed with Pearson and linear regression analysis. Results: In the cataract patients, CRP was (44.36 ± 1.52) D. There was a non-linear correlation between CRP and AL in the total data. However, there was a linear relationship in the segmented data. When AL ≤ 25.06 mm, CRP was negatively linearly correlated with AL (R² =0.397, P<0.001). When AL>25.06 mm, CRP was weakly positively correlated with AL (R² =0.045, P<0.001). Regardless of the length of AL, CRP was negatively correlated with WTW and CCT. There was also a nonlinear relationship between CRP and WTW in the total data. But there was a linear correlation in the segmented data.When 10.52 mm ≤ WTW ≤ 12.46 mm, the negative linear correlation was found between CRP and WTW (R² =0.149, P<0.001), while there was negative correlation among CRP, AL, ACD, and CCT. Conclusion: There is a non-linear correlation among CRP, AL and WTW. To optimize the calculation of intraocular lens (IOL) refractive power with CRP, it is necessary to consider the correlation between AL, WTW, and CRP.

玻璃体切割术是目前临床上常见的眼科手术之一，其应用广泛，且具有良好的治疗效果，但术后仍会出现各种并发症，眼压升高便是其中常见的一种。玻璃体切割术后眼压升高的病因复杂多样，术前原发病的不同、术中处理方式的差异以及术后并发症均可引起眼压升高，根据不同的病因可以选用更合适的治疗方法。早期的眼压升高较易控制，主要采用药物及激光治疗，晚期眼压升高导致继发性青光眼则相对复杂，以手术治疗为主。该文主要对玻璃体切割术后高眼压的原因分析及治疗进展进行综述。

Pars plana vitrectomy is one of the common ophthalmic surgeries in clinic practice currently, which is widely used with good therapeutic effect. However, various complications may still occur after operation. Elevated intraocular pressure is one of common complications. The causes of postoperative ocular hypertension are complex and diverse. Elevated intraocular pressure could be caused by different preoperative primary diseases, intraoperative management methods,and postoperative complication. More appropriate treatment methods can be selected based on different causes. Early elevated intraocular pressure iseasier to control and is mainly treated with medicine and laser. Late elevated intraocular pressure leads to secondary glaucoma, which is relatively complex and mainly treated with surgery. This review mainly states causes and treatment progress of high intraocular pressure after vitrectomy.

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.

      息肉状脉络膜血管病变(polypoidal choroidal vasculopathy,PCV)是亚洲人群中常见的致盲性眼病，发生大出血并发症后严重危害视力且预后差。PCV大出血包括视网膜下出血(subretinal hemorrhage,SRH)和玻璃体积血(vitreous hemorrhage,VH)。SRH的危险因素包括较长病程、簇型PCV、息肉状病灶不消退、合并视网膜色素上皮脱离；其治疗方式包括抗血管内皮生长因子药物、光动力疗法、激光、玻璃体腔注气、眼内注射组织纤溶酶原激活剂、玻璃体切割术或联合治疗等方式，其中，黄斑中心凹是否受累和出血时间是影响治疗方式选择的主要因素。发病年龄较大、白细胞计数较高、天门氨酸转移酶和丙氨酸转氨酶的比值较高、活化部分凝血活酶时间较长、曾行光动力疗法、有玻璃体腔注药治疗史、SRH面积大、出现视网膜色素上皮脱离的PCV患者发生VH的风险高。浓厚的VH通常需行玻璃体切割术，其手术时机和手术方式的选择是临床关注的焦点。鉴于目前PCV大出血的危险因素尚不完全明确、治疗方面也尚未达成共识，需要开展相关临床研究，提供更多依据。

目的：了解干眼患者自我护理能力水平并分析其影响因素。方法：选取2022年2月—6月在中山大学中山眼科中心就诊的干眼患者为研究对象，采用一般资料调查表、自我护理能力量表、一般自我效能感量表对患者进行调查分析。结果：共调查293例干眼患者，其自我护理能力评分为(113.34±9.98)分，处于中等水平。相关性分析中干眼患者的自我护理能力总分与自我效能感得分呈正相关(r=0.421，P<0.001)，多重线性回归分析显示，累计屏幕使用时间>10 h/d、合并全身疾病、低自我效能感评分是干眼患者自我护理能力的危险因素(P<0.05)。结论：干眼患者自我护理能力水平处于中水平，仍需加强。医护工作者在工作中应重点关注屏幕使用时间长、合并全身疾病及自我效能感低的患者，并制定相应的护理对策，以改善患者的自我护理能力水平。

Objective: To understand the self-care ability of patients with dry eye and analyze its infuencing factors. Methods: A total of 293 patients with dry eye were selected from Zhongshan Ophthalmic Center, Sun Yat-sen University from February 2022 to June 2022, the general data Questionnaire the general self-efcacy scale, and the self-care ability scale survey were collected. Results: A total of 293 patients with dry eye were surveyed, and the self-care ability score was 113.34±9.98, which was at the medium level. The total score of self-care ability, the scores of self-concept, self-care responsibility, health knowledge level and self-care skills of patients with dry eye were positively correlated with the scores of self-efcacy (r=0.421, all P<0.001).Multiple linear regression analysis showed that cumulative screen usage time>10 hours/day, comorbid systemic diseases, and low self-efficacy scores were risk factors for self-care ability in patients with dry eye (P<0.05). Conclusions: Te self-care ability of patients with dry eye disease is at a medium level, and still needs to be strengthened. Medical workers should focus on patients with prolonged screen usage, comorbid systemic diseases, and low self-efficacy in their work, and tailor relevant nursing strategies to improve their self-care abilities.

孔源性视网膜脱离(rhegmatogenous retinal detachment,RRD)是一种严重威胁视力的眼部疾病，目前治疗手段以手术为主，手术方式主要有视网膜气体填充术(pneumatic retinopexy,PR)、巩膜扣带术(scleral buckling,SB)以及经睫状体扁平部玻璃体切割术(pars plana vitrectomy,PPV)。目前对于RRD手术术式的选择仍然存在争议，因此研究及制定RRD手术方式抉择的临床策略具有重要的临床意义。而临床上制定RRD患者手术方案往往与患者的年龄、视网膜脱离时间、裂孔的类型、位置、数量、大小等等临床因素有关，该文就影响孔源性视网膜脱离手术抉择的相关临床因素进行综述。

Rhegmatogenous retinal detachment (RRD) is a serious eye disease threatening vision. Surgery is main treatment currently, and surgery approaches include pneumatic retinopexy (PR), scleral buckling (SB), and pars plana vitrectomy(PPV). There is still controversy over the selection of RRD surgery approaches, so it is great significant to study and develop clinical strategies for RRD surgery approaches. The surgical plans for RRD patients are often related to clinical factors, such as the patient’s age, retinal detachment time, type, location, quantity, size, etc. This article reviews the related clinical factors affecting the surgical decision for rhegmatogenous retinal detachment.
