眼睑皮脂腺癌是起源于眼睑部位皮脂腺体的恶性上皮性肿瘤,易复发、转移,主要治疗方式仍以手术切除为主,但患者整体预后并不理想,早期正确诊断和靶向治疗是改善患者预后和改进治疗的关键。眼睑皮脂腺癌临床表现复杂,早期容易误诊或漏诊进而延误治疗,病理检查是其诊断的金标准。此外,目前关于眼睑皮脂腺癌发病机制未完全阐明,癌发生发展的分子生物学过程尚未明确。因此,多方面了解眼睑皮脂腺癌发病机制为靶向治疗提供理论基础是十分必要的。本文主要从眼睑皮脂腺癌发病机制包括遗传因素、表观遗传、外源病毒感染、免疫逃逸、端粒酶学说等方面对眼睑皮脂腺癌作一综述。
Eyelid sebaceous gland carcinoma is a malignant epithelial tumor originating from eyelid sebaceous glands, which is prone to relapse and metastasis. The treatment mainly depends on surgical excision, but the overall prognosis of patients is not ideal. Early diagnosis and targeted therapy are the keys to improve the prognosis of patients.Due to its complex clinical manifestations, early misdiagnosis or missed diagnosis is easy to delay treatment, and pathological examination is still the gold standard for its diagnosis. In addition, the pathogenesis of eyelid sebaceous gland carcinoma is still unclear, and the molecular biological process of the occurrence and development is less understood. Therefore, it is very necessary to understand the pathogenesis of eyelid sebaceous gland carcinoma in various aspects to provide a theoretical basis for targeted therapy. In this paper, the pathogenesis of eyelid sebaceous gland carcinoma was reviewed from the aspects of gene , epigenetic, viral infection, immune escape, , telomerase theory and so on.
抗血管内皮生长因子(vascular endothelial growth factor,VEGF)治疗视网膜静脉阻塞(retinal vein occlusion,RVO)继发黄斑水肿(macular edema,ME)的有效性及安全性已得到广泛证实。但抗VEGF治疗方案尚无统一标准。现行的治疗方案主要包括固定治疗方案、按需(pro re nata,PRN)治疗方案、稳定性标准驱使的按需(stabilization criteria-driven PRN)治疗方案、治疗与延长(treat and extend,T&E)方案。近年来不少研究综合比较了各个治疗方案在改善视功能、量化评估疾病活动性、调整随访频率等多个维度的表现,为临床医生提供选择抗VEGF治疗方案的参考依据。本文旨在回顾并总结近年来对抗VEGF药物治疗RVO继发ME的研究,阐述抗VEGF治疗方案的研究进展。
The efficacy and safety of anti-vascular endothelial growth factor (VEGF) in the treatment of macular edema (ME) secondary to retinal vein occlusion (RVO) have been widely confirmed. However, there is no unified standard for anti-VEGF treatment regimens. Current treatment regimens mainly include fixed treatment regimen, pro re nata (PRN) treatment regimen, stabilization criteria-driven PRN treatment regimen, and treat and extend (T&E) regimen. In recent years, many studies have compared different treatment regimens in composite dimensions,including improving visual function, assessing disease activity quantitatively and adjusting the follow-up frequency,to provide clinicians with a reference of choosing anti-VEGF treatment regimens. The purpose of this article is to review and summarize recent researches on anti-VEGF drugs in the treatment of ME secondary to RVO, and to clarify the research progress in the anti-VEGF treatment regimens.
青光眼睫状体炎综合征(Posner-Schlossman syndrome,PSS)表现为单眼反复发作性非肉芽肿性前葡萄膜炎,伴有眼压升高,可发展为慢性继发性青光眼,最终导致视神经损伤。尽管PSS总体预后良好,但仍有部分患者因反复眼压骤升造成视神经损伤持续进展,甚至导致失明。目前,PSS的确切病因尚不明确,治疗方式以控制炎症及眼压为主。本文将从病因及治疗两方面阐述PSS的研究现状,以期为PSS相关基础研究及临床诊治提供思路及参考。
Posner-Schlossman syndrome (PSS), also called glaucomatocyclitic crisis, is characterized by recurrent non-granulomatous anterior uveitis, accompanied by elevated intraocular pressure. It is able to develop into chronic secondary glaucoma and eventually lead to optic nerve injury. Although the overall prognosis of PSS is favourable, there are still some patients whose optic nerve injury continues to progress and even lead to blindness due to recurrent attacks of ocular hypertension. At present, the exact cause of PSS is not clear, and the treatment is mainly to control inflammation and intraocular pressure. This article will elaborate the research status of PSS from two aspects of etiology and treatment to provide ideas and reference for the basic research clinical diagnosis and treatment of PSS.
过敏性结膜炎经典的发病机制包括了IgE介导的I型超敏反应以及T淋巴细胞介导的IV型超敏反应,其中肥大细胞、肥大细胞脱颗粒释放的组胺、嗜酸性粒细胞等在过敏性结膜炎病理发展中发挥了重要作用。然而,临床发现针对上述机制的治疗药物临床疗效欠佳,有相当数量的过敏性结膜炎患者无法获得较好的生存质量,因此研究和阐明过敏性结膜炎的新机制,寻找新的治疗手段和药物靶点具有重要的临床意义。目前研究发现Th17细胞等多种炎性细胞和IL-17等细胞因子、过敏原介导神经调节机制、菌群失调机制、脂质介质作用方面可能与过敏性结膜炎发病相关,这对过敏性结膜炎新机制的研究有着重大的临床意义。本文将对过敏性结膜炎发病机制的新进展进行综述,以期为过敏性结膜炎的治疗提供新思路。

In recent years, due to the continuous development of economy and society and the increasing social pressure, the incidence rate of mental disorders and dry eyes is increasing, which not only affects people’s physical and mental health, but also creates a certain burden on the social economy. A large number of studies have shown that mental disorder is significantly related to dry eye, and mental disorder is one of the independent risk factors of dry eye. However, in clinical work, the relationship between mental disorder and dry eye has not been paid attention in the past. This paper will start with the correlation between mental disorder and dry eye, explore the mediating effects, summarize the mental disorder factors that affect the separation of symptoms and signs of dry eye, and further advocate interdisciplinary comprehensive management to treat dry eye, form a correct perception of dry eye and reduce the level of pain and health anxiety, In order to provide a new perspective for clinical diagnosis and treatment of dry eye.
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.
