原发性干燥综合征(primary Sj?gren’s syndrome,SS)是一种主要累及外分泌腺体的自身免疫性疾病,患者通常因为严重的干眼症状首先就诊于眼科,大多数临床医师对原发性干燥综合征相关性干眼(Sj?gren’s syndrome dry eye disease,SS-DED)认识不足,可能导致漏诊和误诊。侵入性极小的客观检查及生物标志物的发展,将有助于发现SS-DED的真面目,并可能从新的角度阐释其发病机制,为其诊断、分类及治疗提供新的思路。SS-DED的治疗没有特效的药物,大多数患者需接受多种方法的治疗,以了解哪些方法最有效。
Primary Sj?gren’s syndrome is an autoimmune disease that mainly affects exocrine glands. Patients usually refer to ophthalmologists because of severe dry eye symptoms. Most clinicians have insufficient knowledge with dry eye disease associated with primary Sj?gren’s syndrome probably leading to misdiagnosis or missing the diagnosis.The diagnosis of Sj?gren’s syndrome dry eye disease (SS-DED) is difficult, but the extremely invasive objective examination and the development of biomarkers will help to understand this disease and explain its pathogenesis from a new perspective. There is no specific treatment for the SS-DED, and most patients should receive multiple treatments to select the optimal treatment.
眼肌型重症肌无力(ocular myasthenia gravis,OMG)是一种累及神经肌肉接头突触后膜的自身免疫性疾病。OMG波动性的临床特征易导致较高的漏诊率和误诊率,严重影响患者的生活质量。因此,检测方法在早期确诊OMG中发挥重要作用。本文围绕临床检查、新斯的明试验、自身抗体检测、电生理检测等方面对OMG检测方法作一综述,以期为OMG的早期确诊提供有益的指导。
Ocular myasthenia gravis (OMG) is an autoimmune disease involving the postsynaptic membrane of the neuromuscular junction. The fluctuation of OMG and the clinical characteristics of fatigue easily lead to a high rate of missed diagnosis and misdiagnosis, which seriously affects the quality of life of patients. Therefore, detection methods play an important role in the early diagnosis of OMG. In this paper, OMG detection methods were reviewed in clinical examination, neostigmine test, autoantibody detection, electrophysiological detection, and other aspects, in order to provide useful guidance for the early diagnosis of OMG.
目的:调查民航飞行员视频终端疲劳综合征(visual display terminal syndrome,VDTS)的现状并分析其原因,为民航飞行员眼部保健工作提供依据。方法:对1 631名民航飞行员进行问卷调查,了解暴露时间,比较不同暴露强度人群的不适症状和发病率。结果:民航飞行员视频终端暴露时间为(4.43±2.24) h,VDTS发病率和不适症状检出率均随暴露时间增加而增加。结论:长时间视频终端暴露不利于眼健康。应加强对民航飞行员的眼保健教育,避免或减少视频终端暴露带来的健康危害。
Objective: To investigate the status of visual display terminal syndrome (VDTS) in civil aviation pilots and analyze the causes, so as to provide evidence for eye health care of pilots. Methods: A questionnaire survey was conducted among 1 631 pilots to understand the exposure time and to compare the incidence rate of discomfort in participants with different exposure intensities. Results: The average exposure time of pilots’video terminals was (4.43±2.24) h. The incidence rate of VDTS and the detection rate of discomfort increased with the increase of exposure time. Conclusion: Prolonged exposure to video terminal is not conducive to eye health. The eye health education for pilots should be strengthened to avoid or reduce the health hazards caused by video terminal exposure.

Ophthalmic pathology is an important branch of histopathology. As a bridge and link between basic medicine and clinical medicine, ophthalmic pathology plays an important role in understanding and revealing the characteristics of ocular diseases. The previous generations have laid a solid foundation for ophthalmic pathology with their hard work. Moreover, the advancement of ophthalmic clinical technology and systematic pathology in recent years have further facilitated the development of ophthalmic pathology. The comprehensive combination and in-depth application of cell biology and molecular biology have promoted and expanded the research field of ophthalmic pathology. In addition, new progress has been witnessed in the field of clinical pathology and experimentalpathology constantly. Under the new situation, the development of ophthalmic pathology is faced with both opportunities and challenges.
青光眼不仅常见,而且严重损伤患者的视功能,被认定为全球首位不可逆致盲性眼病。仔细观察发现诊断不及时、治疗不合理、随诊不规律是导致青光眼患者致盲的常见原因。机会性筛查是临床早期发现青光眼患者的主要手段。为了提高筛查的效率,筛查时应当密切关注青光眼的高危人群,包括原发性青光眼患者的直系亲属、老年人群和高度近视患者。此外,要对发生青光眼全过程加深了解,无论是原发性闭角型青光眼,还是原发性开角型青光眼,其病情的进展都存在一个连续体概念。应当在青光眼患者出现症状或严重视功能损伤之前加以诊断。合理治疗应当包括应用适当的药物、激光或手术治疗,将每只患眼的眼压控制到与该眼的视盘和视野改变相适应的目标眼压范围内,尽量提高患者用药的依从性。对青光眼的持续性防治取决于是否有能力评估治疗效果以及发现病情的不稳定性状态,并加以恰当的处理。青光眼是可防可治的眼病。通过加强青光眼的早期诊断、合理治疗和长期随诊,可降低青光眼的致盲率,从而改变青光眼是首位致盲性眼病的现状。
Glaucoma not only is common, but also seriously damages the visual function of the patients, and is recognized as the first irreversible blinding disease in the world. After careful observation, we recognize that untimely diagnosis,unreasonable treatment and irregular follow-up are leading causes to blindness. Opportunistic screening is a main measure to early find the glaucoma in clinical practice. To improve the screening efficiency, the high-risk mass of glaucoma, such as immediate family members of glaucoma patients, older adults and high myopia should be closely focused. In addition, the ophthalmologists should understand the whole process of glaucoma. The development of the primary angle closure glaucoma or primary open angle glaucoma is a concept of continuum. We should make the diagnosis of glaucoma before the patients have any symptoms or serious damage of the visual function. Reasonable treatment should include controlling intraocular pressure in the scope of the target pressure adopting to the optic damage and visual field defect in that eye by drugs, laser or surgery, and as far as possible to improve the drug compliance. Sustained control of glaucoma management depends on the ability to assess the effect of treatment, and to find the instability of the disease and the appropriate management. Glaucoma is a preventable and treatable eye disease. We can decrease the blinding rate and change the current status of the first blinding eye disease for glaucoma.
近视性黄斑病变(myopic maculopathy,MM)是近视最常见的并发症,也是影响病理性近视视功能下降的主要原因。目前,MM的分类系统尚不能完全解释患者黄斑部发生的多种变化,迫切需要一个全面、统一的分类系统来协助沟通和比较临床试验以及国际多中心研究的结果。随着眼底成像技术的发展与应用,最新的近视性黄斑病变分类,即ATN分类系统[萎缩(A)、牵拉(T)、和新生血管(N)]结合眼底照片与光学相干断层扫描(optical coherence tomography,OCT)图片,把黄斑病变分为3类,每一类又根据其严重程度进行分级,这对MM的诊断和治疗提供了较大的临床价值。
Myopic maculopathy (MM) is the most common complication of myopia, which is also the main cause of poor visual function in pathologic myopia. Presently, the classification system of MM cannot properly explain the numerous changes that occur in the patient’s macula. Therefore, a comprehensive and unified classification system is urgently needed to facilitate in communicating and comparing the results of clinical trials and international multicenter studies. With the development and application of fundus imaging technology, the latest classification of MM, namely ATN (atrophy, A; traction, T; neovascularization, N) classificationsystem, which combines fundus photographs and optical coherence tomography (OCT) images, classifies macular lesions into 3 categories according to its severity, generating greater clinical value for the diagnosis and treatment of MM.

干眼是一种临床常见慢性眼表疾病。它不仅能引发患者眼部不适及损害,还易导致患者出现心理障碍。目前最常见的干眼相关心理障碍主要为焦虑、抑郁和睡眠障碍。干眼病情的缓解,不仅需要针对干眼本身的积极治疗,还需要患者保持健康的心理状态。因此,应该关注干眼相关焦虑、抑郁等心理障碍的发病机制及预防、治疗措施。
Dry eye disease (DED) is a common chronic ocular surface disease. It can not only cause discomfort and damage to the eyes but also easily lead to psychological disorders in patients. The most common psychological disorders related to DED are anxiety, depression and sleep disorder. To alleviate the condition of DED, in addition to active treatment for DED itself, it is also necessary for the patients to maintain a healthy psychological state. Therefore, attention should be paid to the pathogenesis, prevention and treatment measures of DED-related anxiety, depression and other psychological disorders.
