晚期糖尿病(diabetes mellitus，DM)患者常出现的糖尿病性视网膜病变能够被发现，而糖尿病性角膜病变(diabetic keratopathy，DK)却时常被人们忽略。近年来的许多研究表明，DK对角膜的结构、代谢、生理功能等多个方面均有重要影响。目前临床上尚无根治DK的有效疗法，现主流疗法多集中于对症治疗以维持光滑湿润的眼表，最大限度地减少视觉损失以及提高舒适度，如局部滴用人工泪液、使用角膜绷带镜及局部使用抗炎药物等，但这些现有的治疗方法对于角膜组织损伤的修复能力有限。近年来出现神经生长因子、胰岛素疗法等新兴的治疗方法，有望未来应用于临床。

The diabetic retinopathy which often occurs in patients with advanced diabetes mellitus (DM) can usually be realized, but diabetic keratopathy (DK) could sometimes be ignored. In recent years, many studies have found out that DK can cause significant abnormal changes in many ways, including structure, metabolism and physiological functions of the cornea. At present, there is no effective therapy to cure DK. The current mainstream therapy mostly focuses on symptomatic treatment to maintain a smooth and moist ocular surface, minimize visual loss and improve comfort, such as local drip of artificial tears, use of corneal bandage lens and local use of anti-inflammatory drugs. However, these existing treatment methods have limited repair ability for corneal tissue damage. In recent years, a number of new treatment methods have emerged, which are expected to be clinically used in the future, such as nerve growth factors and insulin therapy.

视神经脊髓炎谱系疾病(neuromyelitis optica spectrum disorders，NMOSD)是一种中枢神经系统炎性脱髓鞘性疾病，以视神经、脊髓和大脑受累为主要特征，该疾病易复发且致盲、致残率高，严重威胁人类视力和健康。目前NMOSD病因尚不明确，现有治疗方案也无法彻底治愈NMOSD，而动物模型是探索其发病机制与病理生理特点的重要工具。NMOSD动物模型主要建立在抗水通道蛋白4抗体(anti-aquaporin 4 immunoglobulin G，AQP4-IgG)致病基础上，主要包括破坏或绕过血脑屏障(blood brain barrier，BBB)被动转移AQP4-IgG或AQP4特异性T细胞等，目前还没有一种动物模型可以完整模拟人类NMOSD的临床和病理特征，因此在研究中选择合适的动物模型对相关研究至关重要。

Neuromyelitis optica spectrum disorders (NMOSD) is an inflammatory demyelinating disease of the central nervous system. It is mainly characterized by the involvement of the optic nerve, spinal cord and brain. The disease is prone to relapse and has a high rate of blindness and disability, which seriously threatens human vision and health. At present, the etiology of NMSOD is not clear, and the existing treatment schemes can’t completely cure NMOSD. Animal models are important tools to explore its pathogenesis and pathophysiological characteristics. NMOSD animals were mainly established on the basis of anti-aquaporin 4 immunoglobulin G (AQP4-IgG), including destroying or bypassing the blood-brain barrier and passively transferring AQP4-IgG or AQP4 specific T cells. At present, no animal model can completely simulate the clinical and pathological characteristics of human NMOSD. Therefore, it is important to select appropriate animal models for the study. This article reviews various animal models of NMOSD in recent years, and discusses the advantages and disadvantages of various models, in order to provide references for the study of the progress and treatment of NMOSD.

近年来人工智能(artificial intelligence，AI)技术在医学领域的应用发展迅猛，尤其在眼科领域，成果显著，极大地提高了相关影像数据的诊断效率，推动了该领域研究的进展。然而，大多数AI的应用都集中于成人眼病，在婴幼儿眼病方向的研究较少。究其原因，可能是婴幼儿眼部影像数据采集配合度低，部分影像设备应用受限，且相关领域专业眼科医生数量匮乏。然而，婴幼儿期是视觉发育最重要的阶段，也是出生缺陷早期筛防诊治的重灾区，对患儿的视觉发展具有长远且重要的影响，亟需AI相关产品提高婴幼儿眼病筛查效率，缓解医疗资源不足的现状。本文将对近年AI在婴幼儿眼病领域的研究应用现状、进展及存在的相关问题进行综述。

In recent years, the application of artificial intelligence (AI) in medicine, especially in ophthalmology, has developed rapidly with remarkable results. This has greatly improved the diagnostic efficiency of relevant imaging data and promoted further research in this field. However, most applications of AI are focused on adult eye diseases, and few studies have addressed infantile eye diseases. This may be because of the non-cooperative nature of infants, the limited availability of imaging equipment in infants, and the lack of pediatric ophthalmologists. Infancy is the most important stage of vision development. Disturbance during this period have a profound and lasting influence on vision development. Hence, early screening, diagnosis, and treatment of birth defects is important. AI-related products, which improves the efficacy of infant eye disease screening, are urgently needed. This paper reviews the current status, progress, and existing problems of recent research related to application of AI in infantile eye diseases.

幽门螺杆菌(Helicobacter pylori，H P)感染是中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy，CSC)的一个危险因素，但是在HP感染和CSC相关性的研究仍存在争议，目前有两种观点：一是认为HP感染可能是CSC的一个危险因素，二是认为两者之间并没有相关性。本文将就对HP感染是否为CSC危险因素文献进行综述，同时探讨其发病机制。

Helicobacter pylori (HP) infection is a risk factor for central serous chorioretinopathy (CSC). But the existing studies tend to support two distinctively different trends regarding the link between HP infection and CSC. The first group tend to support that: HP infection may be a risk of CSC, and the second tend to claim to no correlation between the two. This paper will review the literature on whether HP infection is a risk factor for CSC and discuss its pathogenesis.
