目的：结合眼科住院医师规范化培训(住培)的特点，建立基于钉钉平台的全面质量管理模式(total quality management, TQM)，探索一种高效的顺应时代特征的眼科教学管理模式。方法：研究团队依托中山大学中山眼科中心，选取82名眼科四证合一的住培一年级的学生作为研究对象，并将其随机分为两组，试验组41人采用基于钉钉平台的TQM模式进行全过程教学管理，采用全员参与、全程跟踪、全面评价的管理模式以保障教学质量。对照组41人接受传统的教学管理模式。观察指标为两组间教学前后测试分数、教学后满意度调查的问卷得分等。结果：通过对两组学生进行课前课后的测试，TQM模式组相较于传统模式组在学习成绩有所提升，课前课后分数的差值分别为40(30,40)分和30(20,50)分，比较差异有统计学意义(P =0.031)。问卷调查结果显示，两组满意度总分比较差异无统计学意义[10(10,10) 分 vs. 10(9,10)分，P =0.207]，但在满意度分项内容掌握性上，TQM模式组分值高于传统模式组[5(5,5)分 vs. 5(4,5)分，P =0.046]。结论：基于钉钉平台的TQM模式在眼科教学中能够有效提高住培的教学质量与学生满意度，相比传统教学管理模式具有更大的教学优势，可为眼科住培提供了一种创新且实用的教学管理模式，对于培养适应时代需求的高水平眼科医师具有重要意义。
Objective: To combine the characteristics of standardized training for ophthalmic resident physicians, establishes a Total Quality Management (TQM) model based on the DingTalk platform, and explored an efficient ophthalmic teaching management model that adapts to the characteristics of the times. Methods: The research team, based at Zhongshan Ophthalmic Center, selected 82 first-year postgraduate students undergoing the national standardized training for resident doctors (STRD) as participants, randomly allocating them into two groups. The experimental group consisting of 41 trainees received TQM-modeled online learning via the DingTalk platform, adopting a management model of full participation, full process tracking, and comprehensive evaluation to ensure teaching quality. While the control group, also comprising 41 trainees, underwent traditional offline instruction. The TQM group engaged in live streaming lectures on the DingTalk platform, whereas the conventional group continued with face-to-face teaching in classroom. Data including pre- and post-teaching scores, as well as scores from satisfaction surveys are analyzed. Results: Comparing pre- and post-teaching scores, significant statistical differences were found between the TQM and traditional groups, with mean score improvements of 40(30,40) points and 30(20,50) points, respectively, indicating statistical significance (P =0.013). Furthermore, the questionnaire survey revealed that the TQM group scored higher than the traditional group in aspects such as course design, clinical relevance, content mastery, and instructor satisfaction. In addition, the questionnaire survey showed that there was no statistically significant difference in the total satisfaction score between the two groups (10(10,10) points vs. 10(9,10)points P =0.207), but in terms of mastery of satisfaction sub items, the TQM model group scored higher than the traditional model group (5(5,5) points vs. 5(4,5) points, P =0.046). Conclusions: The application of a TQM-based model on the DingTalk platform significantly enhances the teaching quality and student satisfaction in the residency training of ophthalmologists, demonstrating greater pedagogical advantages over traditional methods. This efficient ophthalmic teaching management model thus provides a promising solution for standardized residency training in ophthalmology, and holds considerable importance for nurturing highly competent ophthalmologists who can meet the demands of the current era.
目的：应用广角扫频源光学相干断层扫描成像(swept-source optical coherence tomography, SS-OCT)的en face结构投射图研究玻璃体早期液化特征。方法：使用SS-OCT进行18 mm×18 mm 的容积（Cube）扫描，创建并分析健康未成年人（年龄5~18岁）70眼的系列玻璃体en face结构投射图。 结果：在未成年人中，视网膜前的玻璃体包含4种液化结构，分别为后皮质前玻璃体囊袋（posterior precortical vitreous pocket, PPVP）、视盘前Martegiani区（the area of Martegiani, AM）、血管前液化裂隙（prevascular vitreous fissures，PVF）和液化池（cistern）。所有研究眼均能检出PPVP、AM和PVF，其中22眼（31.4%）的PPVP和AM连通。41眼（58.6%）可检出液化池，且其年龄大于未检出液化池的个体（P =0.01），液化池的发生与年龄呈正相关（rs=0.315，P =0.008）。液化池的象限空间分布频率依次为颞上（90.2%）、鼻上（58.5%）、颞下（36.6%）、鼻下（24.4%），最常累及颞上象限（P＜0.001）。 结论：PPVP、AM和PVF是健康人群视网膜前玻璃体早期液化过程中均出现的特征。液化池的发生与年龄呈正相关，最常出现在颞上象限，可能是年龄相关性玻璃体液化变性的结果。
Objective: To investigate the early vitreous liquefaction characteristics using en face structural projection images obtained by wide-angle swept-source optical coherence tomography (SS-OCT). Methods: SS-OCT was employed to perform 18*18mm volumetric (Cube) scans. A series of en face structural projection images of the vitreous were created and analyzed for 70 eyes from healthy minors aged between 5 and 18 years. Results: In minors, four types of vitreous liquefaction structures were identified anterior to the retina: pre-posterior vitreous pocket (PPVP), the preoptic area of Martegiani (AM), pre-vascular liquefaction fissures (PVF), and cisterns. PPVP, AM, and PVF were detectable in all studied eyes, with PPVP and AM being interconnected in 22 eyes (31.4%). Cisterns were observed in 41 eyes (58.6%), and the mean age of individuals with cisterns was higher than those without (P =0.01). The occurrence of cisterns positively correlated with age (r=0.315; P=0.008). The frequency of cistern quadrant distribution was highest in the superotemporal quadrant (90.2%), followed by the superonasal quadrant (58.5%), inferotemporal quadrant (36.6%), and inferonasal quadrant (24.4%). The superotemporal quadrant was the most frequently affected (P <0.001). Conclusion: PPVP, AM, and PVF are features consistently observed in the early vitreous liquefaction process anterior to the retina in healthy individuals. The occurrence of cisterns positively correlates with age and is most common in the superotemporal quadrant, possibly representing the result of age-related vitreous liquefaction degeneration. These findings provide a theoretical foundation for studying the pathogenesis of vitreoretinal interface diseases.
