泪膜的不同组成成分通过相互作用共同维持眼球表面的湿润，从而维持眼部健康。当这些组成成分出现病理性改变，将会不同程度的影响泪膜稳态，从而导致干眼的发生。而瞬目运动一定程度上影响着泪膜组成成分的分布，随着对干眼相关机制研究的逐步深入，以泪膜为导向的诊断(tear-film-oriented diagnosis，TFOD)的新概念被提出，并被逐渐被接受。我们可以通过泪膜破裂方式来确定眼球表面所缺乏的组成成分，并在此基础上对干眼进行诊断，从而定向补充泪膜缺失成分，重新恢复泪膜稳态。本文将着重分析瞬目、泪膜形成及泪膜破裂机制之间的关系，从而进一步明确泪膜定向诊断的新概念及发展方向。
Different components of the tear film work together to maintain the wettability of the ocular surface, thus maintaining eye health. When the pathological changes of these components occur, the tear film homeostasis will be affected to varying degrees, leading to dry eye. Blinking movement affects the distribution of tear film components to some extent. With the continuous development of research and understanding of the concept and mechanism of dry eye, new concepts of tear-film-oriented diagnosis (TFOD) have been gradually proposed and widely accepted. We can determine the components lacking on the surface of the eye through the tear film breakup patterns (BUPs). On this basis, dry eye is diagnosed, so as to replenish the lacking components of tear film directionally and restore the stability of tear film. This paper will focus on analyzing the relationship between blinking, tear film formation and tear film break-up mechanism, so as to further clarify the new concept and development direction of tear-film oriented diagnosis.

During the follow-up within 3 months, the patient’s lens and fundus showed no obvious abnormalities. The injury mechanism of arc light caused by electrical short to the eyeball is discussed.
患儿因“左眼红肿12 d”就诊。左上睑红肿(++++)，眼眶鼻侧可触及约黄豆大小硬结，界不清，质地中等，压痛(?)，伴上睑下垂，遮盖角膜下缘。双眼眼位正，左眼眼球外转轻度受限。眼眶及视神经MRI显示左眼上睑软组织肿胀，考虑炎性改变。入院诊断为左眼特发性眼眶炎性假瘤(Idiopathic orbital inflammatory pseudotumor，IOIP)。予以激素治疗后症状好转且随访期间无复发。本例患儿为拒绝外院活检而就诊于暨南大学附属第一医院的小儿IOIP病例，提示早期规范治疗是降低此病复发率的关键，尤其是儿童患者。
The pediatric patient was referred to our hospital with a 12-day history of left eye redness and swelling. On the orbital and nasal side of the eye, there was a firm, nontender mass about the size of soybeans, with unclear boundary, medium texture. Orbital examination showed left ptosis, covering limbus. Motility examination revealed both eyes were in normal position, and the left eye was slightly limited in extraocular rotation. Magnetic resonance imaging (MRI) revealed evidence of diffuse inflammation of left eyelid, and orbital inflammatory was considered. Excluding other etiologies, the child was diagnosed initially with idiopathic orbital inflammatory. The symptoms improved after hormone therapy and there was no recurrence during follow-up. This case was a case of IOIP in a child who was admitted to the First Affiliated Hospital of Jinan University for refusing biopsy from another hospital. The paper suggests that early standardized treatment is the key to reduce the recurrence rate of this disease, especially in children.

视网膜疾病大多以周边视网膜病变为首要表现，后者的早期诊断、监测对于视网膜疾病的治疗及预防起着至关重要的作用。以往传统眼底成像技术仅能提供20°视网膜的可视范围，即便使用蒙太奇拍摄技术，也只能采集部分眼底范围。目前眼底成像技术已步入最新的超广角时代，其所提供的眼底视野至少可达200°，并且基于该技术的超广角眼底彩色照相、荧光素血管造影、光学相干断层扫描及其血管造影等已广泛应用于临床实践中，对于诊断及评估视网膜疾病发挥重要作用，如糖尿病性视网膜病变、视网膜静脉阻塞、早产儿视网膜病变、视网膜色素变性及视网膜脱离等。本文将从超广角成像技术的产生、发展及其国内外的临床应用现状作一综述，旨在为临床工作及研究提供指导意义。
Retinal diseases primarily feature with peripheral retinopathy, and its early diagnosis as well as the later following up both play a vital role in the treatment and prevention of retinal diseases. In the past, traditional fundus imaging technology can only provide the visual range of 20 degrees. Even if montage photography technology is used, it can only partially reveal the fundus field. At present, fundus imaging technology has entered the latest era of ultra-wide-field, which provides at least 200-degree fundus field of vision. Ultra-wide-field fundus photochromy, fluorescein angiography, optical coherence tomography and angiography based on this technology have been widely used in clinical practice, and play an important role in the diagnosis and evaluation of retinal diseases, such as diabetes retinopathy, retinal vein occlusion, retinopathy of prematurity, retinitis pigmentosa and retinal detachment. This article aims to review the occurrence and development of ultra-wide-field fundus imaging technology and its clinical applications up to now to provide a relative guideline for clinic and research.
白内障作为一种常见的眼科疾病，是全球第一位致盲眼病，目前尚无药物能够治疗，手术是唯一有效的办法。随着现代眼科手术技术的发展以及人工晶状体(intraocular lens，IOL)设计和功能的更新升级，人们对视觉质量的要求越来越高，白内障超声乳化联合IOL植入术已经从单纯的复明手术转变为个性化的屈光手术。为满足不同需求的患者术后获得较好的视觉质量，IOL经历了从单焦点到多焦点、球面到非球面的发展，还有散光型IOL和各类功能性IOL的临床应用，也为患者提供了更多的选择。充分了解不同类型IOL的优势和特点，根据患者自身眼部情况、日常用眼习惯以及需求，个性化地选择IOL植入对视觉质量的恢复和满意度起着至关重要的作用。因此本文将针对不同类型的IOL，从设计与分类、术后临床效果及适应人群进行综述，为IOL的选择提供指导建议。
As a common eye disease, cataract is the first-leading cause of blindness in the world. Currently, there is no drug to treat it, and surgery is the only effective way. With the development of modern ophthalmic surgical technology and the updating and upgrading of the design and function of intraocular lens (IOL), people have higher and higher requirements for visual quality. Cataract phacoemulsification combined with IOL implantation has transformed from a simple vision restoration to personalized refractive surgery. In order to meet the needs of patients with different needs to obtain better visual quality after surgery, IOL has experienced the development from monofocal to multifocal, spherical to aspherical, as well as the clinical application of astigmatic IOL and various functional IOLs, which also provides more choices for patients. Fully understanding the advantages and characteristics of different types of IOLs, according to the patient’s own eye conditions, daily eye habits and needs, individualized selection of IOL implantation plays a crucial role in the recovery and satisfaction of visual quality. Therefore, this article will review different types of IOLs from the aspects of design and classification, postoperative clinical effects and adaptation to the population, and provide guidance for the selection of IOLs.
泪膜是覆盖于眼球表面的一层液体薄膜，从内而外分为黏液层、水液层和脂质层，每层成分的改变都会导致泪膜不稳定，进而导致干眼的发生。在研究泪膜破裂方式及相关泪液成分改变的基础上，学者Yokoi及其团队分别在2012年和2013年提出了有关干眼治疗和诊断的新概念，称为泪膜导向治疗(tear film-oriented therapy，TFOT)和泪膜导向诊断(tear film-oriented diagnosis，TFOD)，就是根据泪膜破裂模式(tear film break-up pattern，TFBUP)的不同，推断出相应的泪膜成分改变，补充不足的泪膜成分，这种诊疗方法目前正逐渐被接受。本文对不同泪膜破裂方式与泪膜成分改变的关系做了汇总分析，旨在为干眼的诊断和治疗提供更为科学实用的指导方案。
Tear film is a layer of fluid film covering the surface of eye global, which is divided into mucus layer, aqueous layer and lipid layer from inside to outside. The change of each layer composition will lead to tear film instability, resulting in the occurrence of dry eye. On the basis of numerous studies on the correlation between tear composition and tear film break-up patterns, Yokoi and his team proposed new concepts on the diagnosis and treatment of dry eye called tear film-oriented therapy (TFOT) and tear film-oriented diagnosis (TFOD) in 2012 and 2013. That is according to different tear film break-up patterns (TFBUP), so changes in tear film composition can be deduced and supplemented, and this diagnosis and treatment method is gradually being accepted. In this paper, we summarized and analyzed the relationship between different tear film break-up patterns and changes in tear film composition to provide a more scientific and convenient guidance program for the diagnosis and treatment of dry eye.
