年龄相关性黄斑变性(age-related macular degeneration,AMD)是一种发生在黄斑区的退行性变,其中湿性年龄相关性黄斑变性(wet age-related macular degeneration,wAMD)以黄斑区新生血管为主要病理特征,是导致老年人视力受损甚至失明的重要原因,视网膜下纤维化是wAMD最常见的自然后遗症,可导致光感受器、视网膜色素上皮(retinal pigment epithelial,RPE)和脉络膜毛细血管受损,导致不可逆转的中心视力丧失。多种基线特征被发现是视网膜下纤维化的危险因素,可用于预测早期视网膜下纤维化的发生。迄今为止,还没有有效的抗纤维化治疗方法,抗血管内皮生长因子(anti-vascular endothelia growth factor, anti-VEGF)治疗是wAMD的一线治疗方案,该治疗方法不能改善视网膜下纤维化,但及时启动治疗可能有助于预防或延缓纤维化的进展,目前多种靶向分子药物正被研发用于抗纤维化的治疗。该文综述了wAMD视网膜下纤维化的临床表现及意义、预测纤维化形成的基线特征、基本发病机制及潜在的抗纤维化治疗方法,旨在为临床诊治工作提供参考。
Age-related macular degeneration (AMD) is a degenerative disease of the macular, and wet age-related macular degeneration(wAMD) is mainly characterized by macular neovascularization, which is an important reason of visual impairment or even blindness in the elderly. Subretinal fibrosis is the most common natural sequelae of wAMD, which can lead to irreversible central vision loss by damaging photoreceptors, RPE, and choroidal capillaries. Multiple baseline features have been identified as the risk factors for subretinal fibrosis, which can be used to predict the early subretinal fibrosis. Heretofore, no anti fibrotic treatment method is effective. Anti vascular endothelial growth factor (anti VEGF) treatment is the first-line treatment for wAMD. This therapy cannot improve subretinal fibrosis, but timely initiation of treatment may help prevent or delay the progression of fibrosis. Currently, multiple targeted molecular drugs are being developed for anti fibrotic treatment. This article reviews the clinical manifestations and significance of subretinal fibrosis in wet age-related macular degeneration, baseline features for predicting the formation of fibrosis, basic pathogenesis, and potential anti-fibrosis treatment methods,aiming to provide reference for clinical diagnosis and treatment.
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.

Late-onset TASS is less common than typical TASS, and the epidemiological characteristics are vary with intraocular lenses. Almost all the factors that can cause typical TASS can cause late-onset TASS, in addition, aluminum element may play a key role in the occurrence of delayed TASS. The clinical manifestations of late-onset TASS are similar to those of typical TASS, with the involvement of the posterior segment more common and hormone therapy effective.
睑板腺功能障碍(meibomian gland dysfunction,MGD)是眼科常见疾病,是蒸发过强型干眼的主要原因。基于人群流行病学的调查显示:MGD亚洲的发病率为46.2%~69.3%。目前,MGD治疗的方式包括眼睑清洁、热敷、睑板腺按摩、人工泪液、抗生素等,其中热敷为常用的家庭治疗方法。由于不同的热敷方式、温度、时间、频次及依从性,导致应用热敷治疗MGD到目前为止还没有统一标准。另外,热敷的不良反应如视物模糊、皮肤烫伤等,也没有引起临床足够重视。因此,为提高热敷的临床疗效及减少其不良反应,未来进行热敷的规范化指导或治疗很有必要。
Meibomian gland dysfunction (MGD) is a common ophthalmic disease, which is the main cause of evaporative dry eye. Population-based studies have suggested that the prevalence of MGD is high in Asia, with a reported incidence of 46.2% to 69.3%. Current modalities of MGD treatment include lid hygiene, warm compresses,massage, artificial lubricants, systemic and topical antibiotics, etc., among which warm compress is a common at-home treatment. Due to different eyelid warming methods, temperature, durations of heat application, frequency and compliance, there is no uniform standard for the application of warm compress to the treatment of MGD.In addition, adverse events of warm compress, such as blurred vision and thermal damage, have not attracted enough attention in clinical practice. Therefore, in order to improve the clinical efficacy of warm compress and reduce its adverse events, it is necessary to conduct standardized guidance or treatment of warm compress in the future. Based on the above considerations, this article will briefly review the application of warm compress to the treatment of MGD.
