角膜移植手术是治疗角膜病变重要且有效的手段。但对眼表功能完全失代偿、多次角膜移植排斥等类型的患者，常规同种异体角膜移植手术成功率却非常低。对于这类患者，人工角膜植入术成为复明的新希望。随着人工角膜的设计和植入方式的不断改进，人工角膜的功效及优点已渐渐突显。目前，波士顿I型(领扣型)人工角膜在全球范围内应用最为广泛。现就波士顿I型人工角膜的基本特征、临床应用及未来发展等方面进行阐述。

The corneal transplantation is an effective option for visually impaired patients with keratopathy to restore vision function. However, the success rate of allograft keratoplasty is still very low for those patients with end-stage ocular surface or repeated corneal graft rejection. For those patients, artificial keratoplasty might be a promising alternative option. The efficacy and advantages of artificial keratoplasty have been gradually highlighted, after consistent improvement of the product design and implantation procedure. Nowadays, the Boston type I (collar button) corneal prosthesis is the most widely used product around the world. In this review, the history, indications, postoperative complications and future prospect of Boston type I corneal prosthesis will be summarized.

玻璃体替代物是玻璃体切割术后的必需品，用于填充玻璃体腔，恢复玻璃体的支撑视网膜、屈光和细胞屏障等功能。严重眼外伤及复杂视网膜脱离引起的视网膜/脉络膜脱离，如选用传统的玻璃体替代物(如硅油)填充，部分患者会出现硅油依赖眼或眼球萎缩，眼球难以保全。折叠式人工玻璃体球囊(foldable capsular vitreous body,FCVB)是我国独立研发的挽救眼球的人工玻璃体，属于国际首创，可以精细模拟自然玻璃体的结构，恢复玻璃体的部分功能。目前临床研究证实FCVB不仅可以有效避免硅油的并发症，还可以维持后房空间，缓慢恢复睫状体的功能，从而治疗硅油依赖眼，阻止眼球进一步萎缩。该文综述了FCVB的研究背景、结构特点、临床应用和拓展研究进展。

Vitreous substitutes are necessary after vitrectomy to fill the vitreous cavity and restore the vitreous to support retinal, refractive, and cellular barrier functions. Severe ocular trauma-induced retinal/choroidal detachment filled with traditional vitreous substitutes (e.g., silicone oil) can lead to silicone oil-dependent eyes and ocular atrophy in some patients, making it difficult to preserve the eye. Foldable capsular vitreous body (FCVB) is an artificial vitreous body independently developed in China to save the eye, which is the first of its kind in the world and can finely simulate the structure of natural vitreous body and restore some of the functions of vitreous body. It has been clinically proven that it can not only effectively avoid the complications of silicone oil, but also maintain the posterior chamber space and slowly restore the function of the ciliary body, thus treating silicone oil-dependent eyes and preventing further atrophy of the eye. This article reviews the research background, structural features, clinical applications and extended studies of FCVB.

甲状腺相关眼病是一种器官特异性自身免疫性疾病，其发病机制复杂，是成人最常见的眼眶疾病，且发病率逐年升高。该病不仅会导致眼球突出、眼睑退缩、睑裂扩大、眼球运动障碍等外观上的变化，且患者往往伴发眼红、眼痛、干涩、异物感、复视、视力下降等不适症状，其中眼表疾病的发病率较正常人明显增高，但其具体发病机制尚待进一步挖掘。目前研究表明甲状腺相关眼病患者的眼表损伤主要与眼表暴露增加、炎症侵犯、激素改变有关。角膜、结膜、泪膜、睑板腺等组织受累发生病理改变是患者表现出不同临床症状的直接原因。文章通过分析近年来国内外关于甲状腺相关眼病与眼表疾病等方面的相关研究，针对甲状腺相关眼病眼表损伤的病理改变及机制研究进展做一综述。

Tyroid-associated ophthalmopathy is an organ-specifc autoimmune disease with complex pathogenesis. It is the most common orbital disease in adults, and its incidence increases year by year. Tis disease can not only lead to appearance changes such as eyeball protrusion, eyelid retraction, eyelid cleat enlargement, eye movement disorders, and patients are ofen accompanied by red eyes, eye pain, dryness, foreign body sensation, diplopia, vision loss and other uncomfortable symptoms, among which the incidence of ocular surface diseases is signifcantly higher than that of normal people, but its specifc pathogenesis needs to be further explored. Current studies have shown that ocular surface injury in patients with thyroid-associated ophthalmopathy is mainly related to increased ocular surface exposure, infammatory invasion, and hormonal changes. Te pathological changes of cornea, conjunctiva, tear flm, meibomian gland and other tissues involved are the direct causes of different clinical symptoms of patients. In this paper, through the analysis of recent domestic and foreign studies on thyroid-associated ophthalmopathy and ocular surface diseases, the pathological changes and mechanism of ocular surface injury in thyroid-associated ophthalmopathy were reviewed.

糖尿病视网膜病变是糖尿病引起的微血管病变之一，是不可逆性致盲的眼病。根据其病程可分为根据其病程可分为非增殖期和增殖期，其中还包括糖尿病性黄斑水肿。全科医师需要检测量裸眼视力、矫正视力和眼压，通过裂隙灯显微镜评估眼前节以及眼底检查来评估眼部整体情况。控制血糖、血压、血脂对改善预后很重要。需要重视餐前、餐后血糖，糖化血红蛋白和代谢记忆，一线降血压药物包括血管紧张素转化酶抑制剂和血管紧张素Ⅱ受体阻断剂，调脂药物首选他汀类，而非诺贝特有额外的视网膜保护作用。干预生活方式，宣教，早期发现也同样重要。全科医师需要进行眼底筛查和评分，及时转诊至眼科治疗。眼科治疗包括全视网膜激光光凝术、经平坦部玻璃体切除术、玻璃体抗血管内皮生长因子药物注射术。

Diabetic retinopathy is one of the microvascular diseases caused by diabetes, it is an irreversible blindness eye disease. According to its course, it can be divided into non-proliferative diabetic retinopathy and proliferative diabetic retinopathy, including diabetic macular edema. Te general practitioner needs to measure the uncorrected visual acuity, corrected visual acuity intraocular pressure, use the slit lamp microscope to exam the anterior segment and fundus to evaluate the overall condition of the eye. Controlling blood glucose, blood pressure and blood lipid is very important to improve the prognosis. Attach importance to pre- and postprandial blood glucose, glycosylated hemoglobin and metabolic memory should be carried out. The first-line antihypertensive drugs are angiotensin converting enzyme inhibitors and angiotensin II receptor blockers. Statins are the first choice for lipid-lowering drugs, fenofibrate has additional protective efect of retinal. Intervention in lifestyle, education and early detection are is important. Te general practitioner needs to perform fundus screening and scoring, timely refer to ophthalmology department for treatment. Ophthalmic treatment includes panretinal laser photocoagulation, pars plana vitrectomy, and intravitreal injection of anti-vascular endothelial growth factor drugs.

该文报道一例中年男性患者，因“头痛伴左侧听力下降”就诊于我院神经外科，经影像学检查诊断为“左侧三叉神经鞘瘤”， 手术前实验室检查发现血象异常，经血液科会诊后诊断为多发性骨髓瘤IgDλ型，于化疗期间并发神经麻痹性角膜炎(neurotrophic keratitis,NK)，可于角膜中央偏下方的上皮及前基质层见到类圆形的灰白色浑浊，呈胶冻样，经局部药物治疗后好转，但残留角膜基质白色浑浊。由于现阶段临床对NK尚欠缺充分认识，易延误诊治，并且本文报道的此例NK患者，因其有化疗病史且于治疗期间出现相关体征，易被误诊为化疗并发细菌性角膜炎，文章通过分析其角膜病变的特征及简单回顾NK的临床特征、鉴别诊断及治疗，以期临床早期识别及治疗此类患者，恢复角膜的光学特性，维持良好的视觉体验。

Tis article reports a case of a middle-aged male patient who visited the Department of Neurosurgery of our hospital due to headache and lef hearing loss. He was diagnosed with lef trigeminal schwannoma by imaging examination and abnormal blood routine before surgery. During chemotherapy and paralytic keratitis (neurotrophic keratitis, NK), can be seen in the lower part of the corneal center of the epithelium and the prestromal layer of round gray and white turbidities, jelly like, afer local drug treatment improved, but residual corneal stromal white turbidities. Due to the lack of full understanding of NK in clinic at the present stage, diagnosis and treatment is easy to be delayed. In addition, the NK patient reported in this paper was easily misdiagnosed as bacterial keratitis complicated by chemotherapy due to his history of chemotherapy and related signs during treatment. Tis paper analyzed the characteristics of keratopathy and briefy reviewed the clinical characteristics, diferential diagnosis and treatment of NK, in order to identify and treat these patients in early clinical stage, restore the optical characteristics of cornea and maintain good visual experience.
