晶状体脱位是临床上常见的疾病，也是晶状体手术中的难点。笔者从既往研究中得到启发，在充分论证了可行性与安全性后原创性地提出了植入性囊袋拉钩技术。经过临床应用与随访，发现该技术的临床效果较为理想，可以最大可能地保留完整的晶状体囊袋，实现人工晶状体的囊内植入，同时笔者也对其设计与操作方法进行了改良。该文就植入性囊袋拉钩的设计、原理、可行性、适应症以及操作细节等进行详细介绍。

Crystalline lens dislocation is a commonly encountered clinical condition that remains challenging in the realm of lens surgery. Inspired by prior studies, the authors originally proposed a technique involving implantable polypropylene capsular hooks after demonstrating their feasibility and safety. After six years of clinical application and follow-up, the technique has shown capable of helping preserve the complete lens capsule to a maximally viable extent and achieve intracapsular implantation of an intraocular lens with high efficacy. At the same time, the authors have also improved the technique’s design and operational method. This paper comprehensively disseminates lessons learned on the principle, design, feasibility, indications, and procedural details of the implantable polypropylene capsular hook technique.

目的：探讨超声乳化晶状体吸除联合囊袋上经巩膜缝线固定人工晶状体(intraocular lens,IOL)植入术治疗球形晶状体(microspherophakia,MSP)的有效性和安全性。方法：采用回顾性分析，选取2019年1月至 2020年6月期间在复旦大学附属眼耳鼻喉科医院进行治疗的MSP患者37例(37眼)，随机分为两组，纳入行超声乳化晶状体吸除联合囊袋上巩膜缝线固定IOL植入术(supra-capsular and scleral-fixated intraocular lens implantation,SCSF-IOL)的MSP患者20例(20眼)和行超声乳化晶状体吸除联合改良型囊袋张力环植入术(transscleral-fixated modified capsular tension ring and in-the-bag intraocular lens implantation,MCTR-IOL)的MSP患者17例(17眼)，观察两组术后最佳矫正视力及并发症等情况。结果：两组术后最佳矫正视力比术前均有改善(P<0.001)，而组间比较差异无统计学意义(P=0.326)。两组的IOL倾斜度相当(P=0.216)。预防性Nd:YAG激光后囊膜切开术在SCSFIOL术后1周至1个月进行。在SCSF-IOL组，2眼(10.00%)需要重复激光治疗，1眼(5.00%)出现囊口偏心。后囊膜混浊是MCTR组最常见并发症(6眼,35.29%)。随访期间两组均未出现IOL脱位、继发性青光眼和视网膜脱离。结论：SCSF-IOL是治疗球形晶状体的简单易行的手术方式，疗效与MCTR-IOL相当。Nd:YAG激光后囊膜切开术是预防SCSF-IOL术后囊袋并发症的必要手段。

Objective: To investigate the efficacy and safety of phacoemulsification combined with supra-capsular and scleral-fixated intraocular lens (IOL) implantation in the treatment of microspherophakia (MSP). Methods: by retrospective analysis, 37 MSP patients (37 eyes) who were treated in our hospital from January 2019 to June 2020 were randomly divided into two groups, including 20 MSP patients (20 eyes) who treated by SCSF-IOL and 17 MSP patients (17 eyes) who treated by transscleral-fixated modified capsular tension ring and in-the-bag intraocular lens implantation (MCTR-IOL). The best corrected vision and complications were observed. Results: the best corrected vision was significantly improved in both groups (P < 0.001), but there was no remarkable difference between the two groups (P = 0.326). The IOL tilt was also comparable (P = 0.216). Prophylactic Nd: YAG laser posterior capsulotomy was performed from 1 week to 1 month after the SCSF-IOL procedure. In the SCSF-IOL group, two eyes (10.00%) needed repeated laser treatment, and one eye (5.00%) had a decentered capsule opening. Posterior capsular opacification was the most common complication (6, 35.29%) in the MCTR group. No IOL dislocation, secondary glaucoma, or retinal detachment was observed during follow-up. Conclusions: SCSF-IOL is a simple and viable surgical option for managing MSP and is comparable with the MCTR-IOL. Nd: YAG laser posterior capsulotomy is a necessary mean to prevent residual capsule complications after the SCSF-IOL procedure.

眼睛由屈光系统和视觉神经系统两大部分构成，是人体最重要的感觉器官之一。眼部各组织的发育或功能异常都可能造成不同程度的视力损害。目前主要通过动物实验或体外细胞培养的方法探究眼病的病理生理机制和治疗手段，但上述两种方法都存在一定的局限性。体外细胞培养不能完全反映器官的形态、结构和生化特征，而动物模型的物种和遗传背景具有异质性。近年来，随着原代组织、胚胎干细胞、诱导多能干细胞衍生的体外三维结构类器官和器官微流控芯片技术的不断发展，构建出了与在体器官的结构、功能更为相似的器官克隆模型，能够提供更敏感、定量、规模化的表型分析，更好地应用于眼的发育、生理结构、疾病机制、个性化医学诊断和治疗方法等方面的研究。目前，眼科的微流控器官芯片与类器官技术在角膜、晶状体、泪腺、视网膜结构发育和疾病模型均展现出巨大的应用潜力。

The eye is composed of refractive system and visual nervous system. It is one of the most important sensory organs of the human body. The abnormal development or function of eye tissues may cause various degrees of visual impairment. At present, the pathophysiological mechanism and treatment of eye diseases are mainly explored through animal experiments and in-vitro cell culture. However, they are of certain limitations. The in-vitro cell culture cannot fully reflect the morphological, structural and biochemical characteristics of organs, whereas the animal models are heterogeneous of species and genetic background. In recent years, with the continuous development of in-vitro three-dimensional structure organoids and organ microfluidic organ-on-a-chip technology derived from primary tissues, embryonic stem cells and induced pluripotent stem cells, organ cloning models more similar to in vivo organs in terms of the structure and function have been constructed. These models can provide more sensitive, quantitative and large-scale phenotypic analysis, and can be better applied to the research of eye development, physiological structure, disease mechanism, personalized medical diagnosis and treatment. At present, microfluidic organ-on-a-chip and organoids technologies have shown great application potential in the structural development and disease models’ construction of cornea, lens, lacrimal gland and retina.

Eye health is an important part of national health. Visual impairment, including blindness, seriously affects people’s physical health and quality of life, increases the burden on families and society, threatens social and economic production activities, and is a major public health and social problem related to people’s livelihood. Amblyopia,as one of the main visual disorders in early childhood, is the primary factor causing low vision in adolescents, which affects their academic and mental health and increases the risk of blindness. Therefore, it is urgent to do a good job in the prevention and rehabilitation of amblyopia. By summarizing existing studies, it is found that traditional treatment methods for amblyopia at home and abroad include occlusion therapy, refractive correction, and depressive therapy, while perceptual learning, visual function training, electronic video games, acupuncture and so on are gradually emerging in recent years and widely used in recent years. There are numerous studies on the impact of age on the rehabilitation of amblyopia. By sorting out the previous research results, this paper puts forward the countermeasures of establishing visual acuity files for children and adolescents, establishing the five- in-one rehabilitation treatment layout model, and combining clinical treatment for adolescent amblyopia, in order to provide reference and choice for the rehabilitation treatment of adolescent amblyopia, and promote the development of the eye health cause of adolescent amblyopia rehabilitation.

近年来，使用人工智能(artificial intelligence，AI)技术对临床大数据及图像进行分析，对疾病做出智能诊断、预测并提出诊疗决策，AI正逐步成为辅助临床及科研的先进技术。生物样本库作为收集临床信息和样本供科研使用的平台，是临床与科研的桥梁，也是临床信息与科研数据的集成平台。影响生物样本库使用效率及合理共享的因素有信息化建设水平不均衡、获取的临床及检验信息不完全、各库之间信息不对称等。本文对AI和区块链技术在生物样本库建设中的具体应用场景进行探讨，展望大数据时代智能生物样本库信息化建设的核心方向。

In recent years, artificial intelligence (AI) technology has been applied to analyze clinical big data and images and then make intelligent diagnosis, prediction and treatment decisions. It is gradually becoming an advanced technology to assist clinical and scientific research. Biobank is a platform for collecting clinical information and samples for scientific research, serving as a bridge between clinical and scientific research. It is also an integrated platform of clinical information and scientific research data. However, there are some challenges. First, clinical and laboratory information obtained is incomplete. Additionally, the information among different databases is asymmetric, which seriously impedes the information sharing among different Biobanks. In this article, the specific application scenarios of AI technology and blockchain in the construction of a Biobank were discussed, aiming to pinpoint the core direction of the information construction of an intelligent Biobank in the era of big data.

当下，我国眼科的发展存在失衡现象，大城市与农村及偏远地区在眼科相关诊疗设施水平、诊疗技术等方面存在巨大差异，仍需探寻新的智能诊疗模式以解决失衡问题。由于眼球是唯一可以直接观察人体血管和神经的器官，眼部可反映其他脏器的健康状态，部分眼科检查的医学图像可对眼部疾病做出诊断等特点，眼科开展人工智能(artificial intelligence，AI)具有独到的优势。此外，人工智能可在一定程度上提高跨时间空间传递信息的精准度及效率。人工智能在眼科及远程信息传递的优势为解决眼科发展失衡状况提供了助力。本文从眼科人工智能在眼科远程医疗相关应用的角度，主要分析并总结当下我国人工智能在眼科相关疾病远程医疗中的发展程度、所具优势以及存在问题，并讨论眼科人工智能在远程医疗的应用展望。

At present, there is an imbalance in the development of ophthalmology in China. There are huge differences in the level of ophthalmology related facilities, diagnosis and treatment technologies between big cities and rural, remote areas. New intelligent diagnosis and treatment models are still needed to solve the imbalance. Since the eye is the only organ that can directly observe the blood vessels and nerves of the human body, the eye can reflect the health status of other organs and diagnosis of eye diseases based on medical images of some ophthalmic examinations can be made as well as other characteristics. Therefore, the development of artificial intelligence in ophthalmology has unique advantages. In addition, artificial intelligence can improve the accuracy and efficiency of information transmission across time and space to a certain extent. The advantages of artificial intelligence in ophthalmology and telematics are helping to solve the imbalance in ophthalmology development. From the perspective of the application of ophthalmic artificial intelligence in telemedicine, this paper mainly analyzes and summarizes the development degree, advantages and existing problems of artificial intelligence in the telemedicine of ophthalmic diseases in China, and discusses the prospect of the application of ophthalmic artificial intelligence in telemedicine.

帕金森病(Parkinson’s disease，PD)是老年人常见的神经系统退行性疾病，眼部及视觉功能障碍是PD常见的非运动症状之一，进一步影响其生活质量。已有研究表明PD患者视网膜内存在多巴胺浓度的减少以及α突触核蛋白的沉积。目前，PD仍缺乏有效的早期诊断及病情评估工具，光学相干断层扫描及光学相干断层扫描血管成像技术可以显示视网膜各层微细结构及微血管的异常，应用该技术研究者发现PD患者视乳头旁视网膜神经纤维层及黄斑区视网膜的厚度均存在不同程度的变薄，视网膜浅层及深层毛细血管丛的毛细血管密度和复杂性下降。进一步研究者应用该技术在PD临床应用中进行了探索，并发现其可用于检测早期PD中发生的病理变化，反映疾病的病程及严重程度，并且在鉴别诊断中起到一定的作用。总而言之，视网膜相关检测可能成为评估PD患者脑病理严重程度的指标，并且帮助疾病诊断和监测疾病的进展，不过这仍需要大样本、多中心的重复研究以提供更多理论依据。

Parkinson’s disease is a common neurodegenerative disease in the elderly, and ocular and visual dysfunction is one of the common non-motor symptoms of PD, further affecting PD patients’quality of life. Reduced dopamine concentrations and deposition of α-synuclein in the retina of PD patients have been shown in studies. At present, there is still a lack of effective tools for early diagnosis and assessment of PD. Optical coherence tomography and optical coherence tomography angiography can reveal abnormalities in the microstructure and microvasculature of the retinal layers, and researchers applying these techniques have found that the thickness of the parapapillary retinal nerve fiber layer and the retina in the macula in PD patients have had varying degrees of thinning, and the density and complexity of capillaries in the superficial and deep capillary plexus of the retina have been reduced. Further, investigators have explored the clinical application of these techniques in PD and have found that they can be used to detect pathological changes occurring in early PD, reflect the course and severity of the disease, and play a role in differential diagnosis. In conclusion, retinal-correlated testing may be an indicator to assess the severity of brain pathology in PD patients and to aid in disease diagnosis and monitoring the progression of PD, although large sample, multicenter replication studies are still needed to provide more reliable results.
