Objective: To analyze the spectrum and epidemiological characteristics of neuro-ophthalmic diseases from single center, and to provide basis for guiding the diagnosis and treatment of neuro-ophthalmic diseases. Methods: Patients with neuro-ophthalmic diseases admitted to the neuro-ophthalmology ward of Chinese PLA General Hospital from January 1, 2010 to December 31, 2021 were enrolled. The age, gender, regional distribution and disease subtypes of all included patients were retrieved and recorded from the electronic case system. Results: A total of 7245 patients with neuro-ophthalmic diseases were enrolled, including 3331 males(46.0%)and 3914 females(54.0%), with a male to female ratio of 1:1.2. The average age was 38.2±17.5 years. 83.25%(6031/7245)were afferent nervous system diseases, 9.92% (719/7245)were efferent nervous system diseases and orbital diseases, and 6.83%(495/7245)were not classified. The ratio of demyelinating optic neuritis(DON)was the highest(40.17%,2910/7245), followed by nonarteritic anterior ischemic optic neuropathy(NAION)(11.37%,824/7245)and traumatic optic neuropathy(TON) (5.15%,373/7245). The ratio of optic nerve atrophy with unknown causes was 7.85%(569/7245). Characteristics of age distribution, the DON and TON were more common in 18-40 age group(the proportion were 48.63% and 44.24%,respectively), the NAION was common in 41-60 age group(66.14%), and the hereditary optic neuropathy was common in younger 18 age group (48.58%). In 2226 DON patients, the proportion of neuromyelitis optica(NMO)/neuromyelitis optica spectrum disorder(NMOSD)-optic neuritis(ON)was the highest(60.02%)and myelinoligodendrocyte glycoprotein antibody(MOG-IgG)ON was 11.68%, while multiple sclerosis(MS)-ON and chronic recurrent inflammatory optic neuropathy(CRION)were relatively low(1.8% and 2.25%,respectively). In DON patients, the male to female ratio was 1:3.08. In NMO/NMOSD-ON patients, the ratio of male to female was 1:8, and that of MOG-ON was 4:5. In atypical ON, the ratio of male to female was higher than that of female(1.28:1). In DON patients, 81.79% of patients were young and middle-aged, and the proportion of children with MOG-ON(less than 18 years old)was 41.15%.Conclusions: DON and NAION are the two most common diseases of neuro-ophthalmic afferent system.

视网膜神经纤维层是视网膜的最内层，主要由来自视网膜神经节细胞的无髓鞘轴突组成，此外还有神经胶质细胞与视网膜血管，其厚度与年龄、眼球增长、眼底结构改变等因素相关。光学相干断层扫描可以清晰展示角膜、视网膜、脉络膜、视神经等高分辨率断层图像，可以在活体上显示生物学组织的细微结构，在临床与科研中已获得广泛应用。在青光眼视神经病变中，光学相干断层扫描可以发现视野异常前的视网膜神经纤维层损害，已成为青光眼早期诊断与视神经损伤程度检测的重要手段。除视神经病外，越来越多的研究表明许多视网膜血管疾病、神经元变性疾病等视网膜疾病也有视网膜神经纤维层的损伤。探讨视网膜疾病与神经纤维层的关系，将有利于进一步推进对视网膜疾病发病机制及病理改变的认识。本文就视网膜神经纤维层的定量评估与多种视网膜疾病的关系展开综述，为其在视网膜疾病中的应用提供参考。

The retinal nerve fiber layer, the innermost layer of the retina, consists mainly of unmyelinated axons from retinal ganglion cells, as well as glial cells and retinal blood vessels , the thickness of which is related to factors such as age, ocular growth and fundus structure changes. Optical coherence tomography (OCT) can clearly display the cornea, retina, choroid, optic nerve and other high-resolution tomography images. It can show the fine structure of biological tissues in vivo, which has been widely used in clinical and scientific research. In glaucomatous optic neuropathy, OCT can detect the damage of retinal nerve fiber layer before abnormal visual field, which has become an important means of early diagnosis of glaucoma and detection of the degree of optic ner ve damage. In addition to optic neuropathy, more studies have shown that many retinal diseases such as retinal vascular diseases and neurodegenerative diseases also have retinal nerve fiber layer injury. Exploring the relationship between retinal diseases and nerve fiber layer will be beneficial to further promote the understanding of the pathogenesis and pathological changes of retinal diseases. This paper reviews the relationship between the quantitative evaluation of retinal nerve fiber layer and various retinal diseases, and provides reference for its application in retinal diseases.

后视路病变是视交叉以后的视觉通路其本身或毗邻结构发生病变，引起视觉功能改变的一类疾病。神经眼科医生比较熟悉枕叶病变引起的对称性同侧偏盲，但枕极(纹状皮质的最后部分)的病变产生中心性对称性同向盲点，此类视野改变容易被忽略或误诊。该文报道一例老年男性患者，因双眼视觉清晰度下降、视物变形就诊。眼科检查：最佳矫正视力：右眼0.8，左眼1.0，FM-100检查提示重度色觉异常，颅脑磁共振成像(magnetic resonance imaging,MRI)提示双侧枕叶脑梗死(右侧枕极部，左侧纹状皮质前部)，24-2 Humphrey视野检查可见双眼同向暗点趋势(不典型)，10-2 Humphrey视野检查可见双眼中心视野同向偏盲(暗点)，故而确诊。后视路病变可引起多种特征性的视野改变，可伴有高级视功能异常及其他神经系统症状和体征，是神经眼科的重要组成部分。该例枕极脑梗死病变产生对称性同向性盲点伴色觉改变患者的诊治过程，提示需关注后视路病变视野改变的多样性及其他视觉功能异常，提高早期诊断率，改善患者预后。

The disease of the posterior visual pathway is a kind of lesion in which the visual pathway itselfor its adjacent structure changes after optic chiasma causes pathological changes, resulting in changes in visual function. Neuro-ophthalmologists are familiar with symmetrical ipsilateral hemianopia caused by occipital lobe lesions, but occipital tip (the last part of the striatal cortex) lesions produce central symmetrical homonymous scotomas, which can easily be overlooked or misdiagnosed. This article reported a case of an olderly male patient treated with decreased binocular visual clarity and distortion. Ophthalmology examination: best corrected visual acuity: 0.8 in the right eye, 1.0 in the left eye; FM-100 examination indicated severe dyschromatopsia; cranial magnetic resonance imaging: infarction of bilateral occipital lobe (right portion of the occipital tip and left anterior portion of striate cortex); 24-2 Humphrey field examination showed a tendency of homonymous scotoma in bilateral eyes (atypical); 10-2 Humphrey field examination showed homonymous hemianopia (scotoma) in the central visual field. These results confirm a diagnosis of the disease of the posterior visual pathway. As an important part of neuro-ophthalmology, the posterior visual pathway can cause various characteristic visual field defects, which can be accompanied by advanced visual dysfunction and other neurological symptoms and signs. The diagnosis and treatment process of this case of occipital tip cerebral infarction with symmetrical homonymous blind spot accompanied by color vision changes suggests that attention should be paid to the diversity of visual field changes and other visual functional abnormalities in the posterior visual pathway lesions, so as to improve the early diagnosis rate and prognosis of the patient s.

YAMANE式后房型人工晶状体巩膜层间固定术是近年出现的一种人工晶状体悬吊术式。该文介绍了笔者结合实际条件对其改良后的手术步骤，手术关键点及使用经验。在缺乏足够囊膜支撑的条件下，此手术方式微创、安全、有效，术后恢复快。在随访期间(最长5年)，视力稳定，未出现人工晶状体脱位、移位、倾斜，人工晶状体夹持及人工晶状体襻暴露等并发症，值得临床推广应用。

The YAMANE intrascleral fixation of posterior chamber intraocular lens (IOL) is a new technique in recent five years for IOL suspension. This article introduces a modified YAMANE technique including surgical procedure, key points and using experience. In the absence of adequate capsular support, this procedure is minimally invasive, safe, effective and has a fast postoperative recovery. During the follow-up period (up to 5 years), the visual acuity was stable, and there were no complications such as luxation of lens, displacement, tilt of intraocular lens, intraocular lens clamping and IOL haptic exposure.

临床上囊袋张力环(capsular tension ring,CTR)与睫状体接触导致的反复持续性高眼压较为少见，本文报告一例改良型CTR植入术后反复持续性高眼压的病例，行“巩膜悬吊线松解术”后高眼压状态有效缓解，考虑可能与巩膜固定缝线过紧，造成改良型CTR局部与睫状体相接触，刺激睫状体分泌过量房水有关。

Recurrent intraocular hypertension caused by contact between capsular tension ring (CTR) and ciliary body is rare clinically. We report a case of recurrent intraocular hy pertension after modified CTR implantation. The IOP returned to normal levels when released the scleral suture. We speculated that the ciliary process irritated by MCTR might increase aqueous humor secretion because of a tight scleral suture.

眼表菌群是定植于眼表的各种微生物群落，以细菌为主。在正常情况下，眼表菌群与人体眼表组织的细胞和平共生，维持眼表的稳态，共同保证眼表的健康。但在环境改变或免疫力低下的情况下，眼表菌群会发生变化，与眼部疾病的产生与发展关系密切，对人类的健康造成巨大的危害。随着组学研究的不断发展，我们对眼表菌群有了新的认识，为眼表疾病的发病机制、治疗开辟了新的思路，同时也提出了新的挑战。本文对国内外眼表菌群与疾病关系进行综述，为眼表疾病的发生、发展以及治疗提供参考。

The microbiome of the ocular surface consists of various microbial communities that colonize on the eye surface, mainly bacteria. The stabilization of the microbiome and the other ocular surface components plays an important role in maintaining the homeostasis of the ocular surface. However, unpredictable changes of ocular surface microbiome are strongly associated with ocular surface diseases in the situation of environmental changes or destruction of immune system. With the innovation of inspection technology, the current gene sequencing technology is applied to detect the ocular surface microbiome and confirm that the eye microbiome is closely related to ocular surface diseases. This paper investigates the corelation of ocular surface microbiomes and diseases. Moreover, we provide areference for the occurrence and development of ocular surface diseases and their treatment.

阿尔茨海默病(Alzheimer’s disease，AD)是发生于老年期或老年前期的中枢神经系统退行性病变，以进行性认知功能障碍为特征。随着社会老龄化加剧，AD已成为全球公共卫生问题，亟需研发更敏感、便捷和经济的筛查技术进行早期防控。眼球运动与认知功能密切相关，且眼球运动检查有非侵入性、成本低、检查时间短等优点。研究眼球运动异常和认知功能障碍之间的相关性，有助于研发更简便易操作的认知功能障碍筛查工具。随着人工智能技术的发展，机器学习算法强大的特征提取和计算能力对处理眼球运动检查结果有显著优势。本文对既往AD患者与眼球运动异常之间的相关性研究进行综述，并对机器学习算法模型辅助下，基于眼球运动异常模式进行认知功能障碍早期筛查技术开发的研究前景予以展望。

Alzheimer’s disease (AD) is a degenerative disease of the central nervous system that occurs in old age or early old age. It is characterized by progressive cognitive dysfunction. With the world population aging, AD has become a global public health problem. The development of a more sensitive, convenient, and economic screening technology for AD is urgently needed. The eye movement function is closely related to cognitive function. Moreover, eye movement examination has advantages including non-invasiveness, low cost, and short examination time. Researches on the correlation between abnormal eye movement and cognitive dysfunction can help to develop a simple and easy-to-use screening tool for cognitive dysfunction. With the development of artificial intelligence technology, the dominant feature extraction and computing capabilities of machine learning algorithms have a significant advantage in processing eye movement inspection results. This article reviews the correlation between AD and eye movement abnormalities aiming to provide the research prospects of early screening technology development for cognitive dysfunction based on abnormal eye movement with the application of machine learning models.

近年来随着医疗领域数字化、信息化建设的加速推进，人工智能的应用越来越广泛，在眼科医学方面尤为突出。婴幼儿处于视觉系统发育的关键时期，此时发生的眼病往往会造成不可逆的视功能损伤，带来沉重的家庭和社会负担。然而，由于婴幼儿群体的特殊性以及小儿眼科医生的短缺，开展大规模小儿眼病筛查工作十分困难。最新研究表明：人工智能在先天性白内障、先天性青光眼、斜视、早产儿视网膜病变以及视功能评估等领域已经得到相关应用，在多种婴幼儿眼病的早期筛查、诊断分期、治疗建议等方面都有令人瞩目的表现，有效解决了许多临床难点与痛点。但目前婴幼儿眼科人工智能仍然不如成年人眼科发展充分，亟须进一步的探索和研发。

In recent years, with the acceleration of digitalization and informatization in medical field, artificial intelligence (AI) is more and more widely applied, especially in ophthalmology. Infants are in the critical period of visual development, during which eye diseases can lead to irreversible visual impairment and bring heavy burden to family and society. Due to the particularity of infants and the shortage of pediatric ophthalmologists, it is challenging to carry out large-scale screening for eye diseases of infants. According to the latest studies, AI has been studied and applied in the fields of congenital cataract, congenital glaucoma, strabismus, amblyopia, retinopathy of prematurity, and evaluation of visual function, and it has achieved remarkable performance in the early screening, diagnosis stage and treatment suggestions, solving many clinical difficulties and pain points effectively. However, AI for infantile ophthalmology is not as developed as for adult ophthalmology, so it needs further exploration and development.

白内障是全球第一大致盲眼病，表现为由多种原因导致的晶状体病变，进而出现视物模糊的现象，严重者会进一步丧失视力。白内障的类型较多，发病机制尚未完全阐释清楚，氧化应激是目前公认的主要影响因素。药物治疗一直是白内障患者临床治疗的一大难题，目前市面上还没有能够真正逆转白内障的药物，现有的药物仅能在一定程度上缓解白内障的进展。手术治疗仍是现阶段唯一有效的治疗方式，但经济因素和术后并发症的风险限制了部分患者通过手术恢复视力。白内障的治疗一直是眼科领域研究的重点，目前研究主要集中在两个战略方向上：优化手术技术并结合更优的围术期药物治疗方案以减少并发症，以及对疾病机制进行基础研究以促进新靶点药物的发现。有效的药物治疗一直是目前临床治疗的一大缺口，近年来研究者在白内障机制探索和新药研发上取得了显著进展，多个新的治疗靶点以及相关治疗药物不断被发现，但相关药物真正进入临床还面临着诸多挑战。文章主要从机制研究进展、药物治疗现状和前景较好的白内障药物临床研究进展等进行综述，旨在为新的白内障药物研发提供最新的参考。

Cataracts remain the leading cause of blindness globally. They manifest as lens opacification triggered by various factors, leading to blurred vision. In severe cases, patients may eventually lose their vision entirely. There are many types of cataracts, and their pathogenesis has not been fully clarified. Currently, oxidative stress is widely acknowledged as the primary influencing factor. Pharmacological intervention remains a significant clinical challenge in cataract management. At present, there are no drugs on the market capable of truly reversing cataracts; existing medications can only alleviate the progression of the condition to a certain extent. Surgical treatment remains the only effective approach at this stage. However, economic limitations and the risks of postoperative complications hinder its accessibility for certain patient groups. The treatment of cataracts has consistently been a research hotspot in the field of ophthalmology. Current research mainly centers on two strategic approaches: optimizing surgical techniques alongside improved perioperative pharmaceutical regimens to minimize complications, and conducting basic researches on disease mechanisms to facilitate drug discovery. Effective drug treatment has long been a major gap in current clinical treatment. In recent years, significant progress has been achieved in the exploration of cataract mechanisms and the development of new drugs. Despite the remarkable advancements in uncovering cataract pathogenesis and identifying novel therapeutic targets in recent years, substantial challenges remain in translating these discoveries into clinically applicable medications. This article reviews the progress in mechanism research, the current state of pharmacological interventions, and the clinical research developments of several promising cataract drugs, aiming to provide the latest reference for the research and development of new cataract drugs.

越来越多的证据表明，空气污染可严重损害人体健康，成为全球疾病负担的主要原因。并且污染空气中的主要成分空气颗粒物可渗透到肺部和心血管系统，引起缺血性心脏病、肺炎、慢性阻塞性肺疾病甚至肺癌，导致空气污染相关的发病率和死亡率升高。城市颗粒物作为城市居住人群面临的主要空气污染问题，被证实与多种炎症性眼表疾病密切相关，如过敏性结膜炎、角膜炎、干眼等。高浓度城市颗粒物暴露还会引起睑板腺病理性结构改变和功能异常，诱发炎性睑板腺功能障碍。文章综述了城市颗粒物相关的眼表疾病类型及其致病机制的最新研究，旨在阐明空气污染对于眼表组织的损害和相应的潜在治疗靶点，指导临床上环境相关眼病的诊断与治疗。

More and more evidence indicate that air pollution can seriously damage human health and become a major cause of the global disease burden. The main component of air pollution, particulate matter, can penetrate the lungs and cardiovascular system, causing ischemic heart disease, pneumonia, chronic obstructive pulmonary disease, and even lung cancer, leading to an increase in the incidence and mortality rates related to air pollution. Urban particulate matter, as the main air pollution problem faced by urban residents, has been shown to be closely related to various inflammatory eye diseases, such as allergic conjunctivitis, keratitis, and dry eye. Our research further confirms that exposure to high concentration of urban particulate matter can also cause pathological structural changes and functional abnormalities in the meibomian gland, leading to inflammatory meibomian gland dysfunction. This review comprehensively summarizes the latest research on the eye surface diseases related to urban particulate matter and their pathogenic mechanisms, aims to elucidate the damage of air pollution to eye surface tissues, identify potential therapeutic targets, and guide the diagnosis and treatment of environmentally related eye diseases in clinical practice.
