人工智能(artificial intelligence，AI)为解决中国患者“看病难”问题提供了可行方案。眼科AI已实现为患者提供筛查、远程诊断及治疗建议等方面的服务，能显著减轻医疗资源不足的压力和患者的经济负担。而AI的应用过程中，给医疗管理带来的挑战应引起重视。本文从医疗管理的角度，总结分析AI在眼科医疗过程中，尤其是交接环节中出现的主要问题，提出对策与建议，并讨论AI在眼科医疗的应用展望。
Artificial intelligence (AI) has been proposed as a potential solution to address the shortage of ophthalmologists in China. With the increasingly extensive application of AI in the field of ophthalmology, many potential patients with eye diseases have access to a higher quality of medical services. At the same time, new challenges will emerge and proliferate with the advancement of AI application. This paper focuses on the patient handoffs process and discusses two challenges brought by the application of AI, namely “communication” and “standardization”. Natural language processing techniques and the development of standardized databases are proposed to solve each of these challenges. The application prospects of AI in ophthalmology are eventually discussed.
光学相干断层成像(optical coherence tomography，OCT)自1991年发明以来，在生物成像尤其在眼科和心血流成像中起越来越重要的作用。OCT的发展经历了早期的时域系统及最新的频域系统。其中频域系统又分为谱域OCT(spectral domain OCT，SD-OCT)系统和扫频OCT(swept source OCT，SS-OCT)系统。随着眼科临床应用对系统速度、灵敏度及功能化要求的不断提升，眼科扫频OCT已经走向成熟并逐步商用化。本文将简介扫频OCT的原理，并归纳扫频OCT相对于时域和谱域OCT系统的优势，并展示其在眼科临床的应用。
Optical coherence tomography (OCT) has played an important role in biomedical imaging, especially in ocular and cardiovascular imaging. OCT technology has evolved to frequency domain technology from early time-domain technology due to the advantages of high sensitivity and high speed of frequency domain techniques. The swept source OCT is a type of frequency domain OCT. With the increasing requirements for system speed, sensitivity, and functionality in clinical application, swept source OCT is gradually becoming commercially available and widespread in clinical application. In this paper, the principle of swept source OCT was introduced, the advantages of swept source OCT over time domain and spectral domain OCT systems were summarized, and its clinical application in ophthalmology was demonstrated.
随着人口老龄化、生活方式的改变，眼科疾病患病人数的增加、国家眼病诊疗相关政策的持续推动、居民健康意识的逐渐提升，眼科门急诊患者数量持续增长，亟需构建科学的眼科急诊预检分诊标准，合理配置医疗资源，确保患者得到及时、恰当的治疗。国外已有医院依据患者症状或体征的严重程度对患者进行等级划分，建立起相对成熟的眼科急诊预检分诊模式，我国目前尚没有统一的、权威的眼科急诊预检分诊标准，国内外现行的眼科急诊预检分诊模式的分诊精准度及临床适用性有待进一步探索。该文通过综述国内外眼科急诊分诊标准及应用评价、眼科远程急诊预检分诊方式研究进展，以期为构建符合我国国情的、科学有效的眼科急诊预检分诊标准、提高眼科急诊分诊质量提供参考。
With the aging of population, the changing of lifestyle and the increasing number of ophthalmic emergency patients,Chinese national policies related to ophthalmic diagnosis and treatment are continually promoted, and residents' health awareness are gradually improved, the volume of ophthalmic outpatients and emergency patients continues to increase. It is urgent needed to establish scientific ophthalmic emergency pre-examination and triage criteria, to reasonably allocate medical resources, and to ensure that patients receive timely and appropriate treatment. The relatively mature ophthalmic emergency pre-examination and triage models with the severity of patients' symptoms or physical signs,have been established in foreign hospitals. Currently, there is no unified and authoritative ophthalmic emergency triage criteria in China. The accuracy and clinical applicability of the existing ophthalmic emergency triage models at home and abroad need to be further explored. This article reviewed the ophthalmic emergency triage criteria and application evaluation at home and abroad, and remote emergency triage in ophthalmology, in order to provide a reference for establishing a scientific and effective ophthalmic emergency triage criteria comformed Chinese national conditions, and improving the quality of ophthalmic emergency triage.

The content of the questionnaire includes 3 parts: the basic information of the respondents, evaluation of live-streamed classroom teaching and its satisfaction. The SPSS 20.0 statistical software was used for data analysis. Results: A total of 92 students completed the questionnaire survey, including 37 males and 55 females, aged (22.9±0.71) years. The sores of content, resource, platform design, platform technology and learning communication of live-streamed classroom were 40.60±4.582, 17.43±2.814, 13.07±1.759, 13.14±2.052 and 20.82±2.685, respectively. Among all items, the scores of the similarity of offline classroom communication styles and enthusiasm for communication were lowest, with the points of 3.42±1.131 and 3.85±0.864, respectively, and the correlation of the two items were statistically significant (correlation coefficient =0.276, P=0.008). The total score of the live-streamed classroom satisfaction was 13.52±1.872. The classroom content has a significant effect on the satisfaction of the live-streamed classroom (P<0.001), and the standardized regression coefficient is 0.687. Compared with the pre-class test, the post-class test score was 65.9±11.4, with a statistically significant improvement (P=0.033); however, compared with grade 2013, the course test score of the students of grade 2015 was 72.6±7.0, with a statistically significant reduction (P=0.009). Conclusion: The classroom content has an important impact on the satisfaction of live-streamed classroom teaching. It is necessary to pay attention to the communication difference between live -streamed classroom and offline classroom settings, and improve the enthusiasm for participation in the study communication, in order to improve the effectiveness of teaching.

外泌体(exosome)是直径30 nm~150 nm的纳米级囊泡，由脂质双分子层、蛋白质和遗传物质组成。人体内几乎所有类型的细胞都能分泌外泌体。它们在细胞通信、免疫调节、炎症反应和新生血管形成中起着关键作用。目前，外泌体已在肿瘤、心血管及泌尿系统中得到广泛研究。近年来，外泌体在眼科疾病中的作用受到越来越多的关注。外泌体在角膜病变、年龄相关性黄斑病变、糖尿病视网膜病变、青光眼等常见眼科疾病的发生、发展中发挥重要作用。不同间充质干细胞来源的外泌体在眼科疾病中的治疗潜力是当下的热点。间充质干细胞来源的外泌体具有与间充质干细胞相似的抗炎、抗凋亡、神经保护和组织修复的作用，因此外泌体可能是多种眼科疾病无细胞疗法治疗研究的新方向。进一步了解外泌体的生物学特性以及外泌体在眼科疾病的最新研究进展，将为相关眼病的发生机制和防治策略提供参考依据。
Exosomes are nanoscale vesicles with a diameter of 30 nm to 150 nm, which are composed of lipid bilayers, proteins, and genetic material. Almost all types of cells in the human body can secrete exosomes. Tey play key roles in cellular communication, immune regulation, infammatory responses and neovascularization. At present, exosomes have been widely studied in tumors, cardiovascular and urinary systems. In recent years, the role of exosomes in eye diseases has attracted more and more attention. The exosomes play an important role in the occurrence and development of common eye diseases such as keratopathy, age-related macular disease, diabetic retinopathy, glaucoma, etc. Currently it is a hot topic that the therapeutic potential of extracellular vesicles derived from diferent mesenchymal stem cells in eye diseases. Te exosomes derived from mesenchymal stem cells have anti-infammatory, anti apoptotic, neuroprotective and tissue repairing effects, which are similar to those of mesenchymal stem cells. Thus, exosomes may be a novel direction of research in the treatment of many eye diseases without cell therapy. Further understanding of the biological characteristics of exosomes and the latest research progress of exosomes in common eye diseases will provide reference for the pathogenesis and prevention strategies of related eye diseases.

Objective: To understand the current situation of scientific research ability of postgraduates with professional degrees in ophthalmology and put forward improvement measures. Methods: A questionnaire survey was conducted on the current situation of scientific research ability, scientific research obstacles and scientific research training willingness, 76 postgraduate students of different grades majoring in ophthalmology of three affiliated hospitals of Harbin Medical University were involved. Results: Under the merging residency training system, the foundation of scientific research and clinical knowledge of postgraduates is relatively weak, and the heavy clinical learning task were the main obstacles to scientific research of postgraduates. Conclusion: It is proposed that the teaching bases could provide multi-mode scientific research training to cater to students' individual needs. Not only clinical diagnosis and treatment training could be strengthened to cultivate students’ scientific research thinking, but scientific research topic selection strategy could be optimized by to meet the demand for development of times and broaden students’ scientific research vision.
