甲状腺相关眼病(thyroid-associated ophthalmopathy,TAO),又称Graves眼病,是与甲状腺疾病密切相关的一种器官特异性自身免疫性疾病。眼球突出是TAO的主要临床表现之一,也是临床上多数患者就诊的原因。眼球突出一方面会影响美观,另一方面可因眼睑闭合不全导致暴露性角膜炎或因眼眶压力增大导致压迫性视神经病变。眼眶减压术用于重度TAO已有过百年历史,从最早经外眦皮肤切开的传统外部切口入路进行骨性眼眶减压及脂肪减压到内镜下经鼻入路眼眶减压术,其安全性和有效性均已得到肯定。术后复视是眼眶减压术常见的并发症。近年来,随着眼眶减压术的发展,其越来越多地用于美容目的以矫正眼球突出。然而术后的新发复视仍然是困扰众多相关眼科医疗工作者的难题。近年来,多项研究对术后新发复视的相关因素进行了探讨,并由此对眼眶减压术进行改良,在对术后新发复视的减少方面取得不同程度的进展。该文对眼眶减压术后新发复视的研究进展进行综述,旨在促进专科医生更精准地开展TAO的手术,进而提高手术患者术后的生活质量及手术满意度。
Thyroid-associated ophthalmopathy (TAO), known as Graves’orbitopathy, is an organ specific autoimmune disease closely related to thyroid diseases. Exophthalmos is one of the main clinical manifestations of thyroid related ophthalmopathy and is also the reason for most patients seeking medical atention in clinical practice.Eyeball protrusion can afect aesthetics on the one hand, and on the other hand, it can lead to exposed keratitis due to incomplete closure of the eyelids or compressive optic neuropathy due to increased orbital pressure.Orbital decompression has been used to treat severe TAO that threatens vision for over 100 years, and its safety and efectiveness have been confrmed.However, postoperative new diplopia remains a challenge for many ophthalmic medical workers.In recent years, many studies have explored the relevant factors of postoperative new diplopia, and improved the surgery, achieving varying degrees of progress in reducing postoperative new diplopia.Tis article reviews the research progress of new diplopia afer orbital decompression, aiming to promote more accurate surgery for thyroid related eye diseases by specialized doctors.
房角镜辅助的内路360°小梁切开术(Gonioscopy-Assisted Transluminal Trabeculotomy,GATT)是近年来国内外开展的新型微创青光眼手术,是一种改良的小梁切开术。GATT将微导管(iTrack)环穿Schlemm's管后,利用微导管张力全周切开小梁网及Schlemm's管内壁,重建生理性房水流出通道,避免小梁网阻力,实现房水从前房直接进入集液管,通过增加房水流出机制降低眼压。GATT适应证广泛,主要应用于开角型青光眼,包括原发型开角型青光眼和继发性开角型青光眼,同时可运用于闭角型青光眼。GATT微创、不依赖滤过泡、能明显减少降眼压药物的使用、中远期疗效稳定、安全性高、较少发生威胁视力的并发症,可作为开角型青光眼的首选手术方式。本文将对GATT在青光眼中的应用、手术步骤、作用机制、有效性、并发症及影响疗效的因素等进行综述,以期为其临床运用提供参考。
As a modifed trabeculotomy, Gonioscopy-Assisted Transluminal Trabeculotomy (GAT) is a new type of minimally invasive glaucoma surgery developed at home and abroad in recent years. GAT inserts a microcatheter (iTrack) into the Schlemm's canal and advance the catheter through the canal circumferentially 360°, then circumferentially fracture the trabecular meshwork and inner wall of Schlemm’s canal. Tis method can reduce intraocular pressure by increasing the outfow of aqueous humor. Te physiological outfow pathway of aqueous humor is reconstructed, which can avoid the resistance of trabecular meshwork and realizing the direct entry of the aqueous humor directly into the collector channel from the anterior chamber. With a wide range of indications, GAT is mainly used in open-angle glaucoma, including primary open-angle glaucoma and secondary open-angle glaucoma, and is also used in primary closed- angle glaucoma. Additionally, GATT can be the preferred surgical modality for open-angle glaucoma, as it has the following advantages: minimally invasive, independent of fltration bleb, can signifcantly reduce the use of medications, stable medium- and long-term efcacy, high safety, and has fewer sight-threatening complications. In order to provide a reference for clinical application, this article reviews the indications, mechanism of action, surgical procedures, efectiveness, complication and factors afecting therapeutic efect.

Primary pterygium is a non-neoplastic degenerative tissue that grows subepithelially, and its pathogenesis is mainly related to ultraviolet exposure, however, the full mechanism of primary pterygium remains unclear. In recent years, with the development of medical research, it is found that the occurrence and development of primary pterygium are closely related to a variety of factors. Viral infection, oxidative stress, inflammatory response, inactivation of tumor suppressor genes, DNA methylation and other factors have been shown to be involved in the pathogenesis of pterygium. In addition, imbalances of apoptosis and proliferative proteins, extracellular matrix regulators, and epithelial-mesenchymal cell transformation also play important roles in the pathogenesis of primary pterygium. These can lead to abnormal cell growth and division, which in turn induces the formation of pterygium. However, the interaction between these factors and their specific mechanisms of action in the pathogenesis process still need to be further studied. In this article it reviews the current pathogenesis of primary pterygium, and deeply explores the pathogenesis of primary pterygium and the interaction of different related factors in the pathogenesis of primary pterygium. By understanding the role of different factors in the pathogenesis process, we can provide more precise and effective prevention and treatment strategies for clinical practice, and better treatment outcomes and quality of life for patients.

铁死亡是一种以铁沉积和脂质过氧化为主要特征的新型细胞死亡方式,目前在眼科方面的研究不断深入。视网膜因其本身功能和结构特点,易受到氧化应激的影响,而铁死亡已被证明在年龄相关性黄斑变性、青光眼、糖尿病性视网膜病变、视网膜色素变性等视网膜退行性疾病进程中发挥了重要作用。铁代谢途径作为铁死亡的主要调控方式之一,可通过调控细胞内铁稳态,介导芬顿反应形成脂质过氧化物,从而调控细胞铁死亡。转铁蛋白(transferrin,TF)、二价金属转运蛋白1(divalent metal transporter 1,DMT1)、铁蛋白(ferritin,FT)、铁转运蛋白1(ferroportin 1,FPN1)等铁代谢途径关键蛋白涉及细胞内铁离子的摄入、利用、储存、输出等多个方面,对细胞内铁稳态具有重要影响。通过调控铁代谢途径关键蛋白减少铁沉积而抑制铁死亡,可能成为延缓和治疗视网膜退行性疾病的新途径。文章对铁死亡概念、视网膜与铁死亡、铁死亡调控途径、铁代谢途径关键蛋白与视网膜退行性疾病的研究进展进行综述。
Ferroptosis, a novel form of cell death primarily characterized by iron deposition and lipid peroxidation, has been increasingly studied in the feld of ophthalmology. Te retina, due to its specifc functions and structure, is susceptible to oxidative stress. Ferroptosis has been proven to play a crucial role in the progression of retinal degenerative diseases such as age-related macular degeneration, glaucoma, diabetic retinopathy, and retinitis pigmentosa. Te iron metabolism pathway is one of the main regulatory mechanisms of ferroptosis, regulating intracellular iron homeostasis and mediating the formation of lipid peroxides through the Fenton reaction, thereby controlling cellular ferroptosis. Iron metabolism pathways, as one of the main regulatory mechanisms of ferroptosis, can regulate intracellular iron homeostasis and mediate the formation of lipid peroxides through the Fento reaction, thereby controlling cellur ferroptosis. Key proteins involved in iron metabolism pathways, including transferrin (TF), divalent metal transporter 1 (DMT1), ferritin (FT), and ferroportin 1 (FPN1), act as important roles in various aspects such as intracellular iron intake, utilization, storage, and export, exerting signifcant impacts on intracellular iron homeostasis. Regulating key proteins in iron metabolism pathways to reduce iron deposition and inhibiting ferroptosis may emerge aas a novel approach for delaying and treating retinal degenerative diseases. Tis article provides a comprehensive review of the concept of ferroptosis, the relationship between the retina and ferroptosis, the regulatory mechanisms of ferroptosis, and the research progress on key proteins in iron metabolism pathways and retinal degenerative diseases.
哺乳动物雷帕霉素靶蛋白(mammalian target of rapamycin,mTOR)是一种蛋白激酶,在体内主要参与营养水平、生长代谢的调节。mTOR是癌症、衰老和其他代谢相关病理性疾病的重要靶点,参与了增殖、转分化、自噬等多种生物学过程。眼被认为是具有免疫特权的区域,由于血管系统会影响视力,眼的血管系统位于中心光路以外。眼的许多区域都有将免疫细胞运输至发育不良、受损或衰老有关的病变部位的机制。尽管免疫应答主要是为了修复或保护自身,但是免疫细胞可能会分泌一些细胞因子,导致炎症或纤维化,进而损害视力。研究证实,mTOR与翼状胬肉、年龄相关性黄斑变性(age-related macular degeneration,AMD)、青光眼、白内障、糖尿病视网膜病变(diabetic retinopathy,DR)、眼部肿瘤等多种眼病密切相关。目前,mTOR抑制剂通常被用作免疫抑制剂,用于癌症的治疗,但mTOR抑制剂用于眼部疾病的报道尚少。因此,该文就mTOR信号通路在相关眼科疾病中的作用、调控机制、药物治疗等方面进行简要综述,为相关眼科疾病的病理机制与治疗提供思路,以便后续开展更深入的研究。
Mammalian target protein of rapamycin (mTOR) is a protein kinase that primarily involves in the regulation of nutrient levels andgrowth metabolism in vivo. mTOR serves as a crucial target for cancer, aging, and other metabolic related pathological diseases, participating in various biological processes such as proliferation, transdifferentiation, and autophagy. Te eye is considered an area with immune privilege, as the vascular system afects vision and is located outside the central light path. Many areas of the eye have mechanisms for transporting immune cells to the afected areas related to developmental, damaged, or aging. Although the immune response is primarily aimed at reparing or protecting itself, immune cells may secrete some cytokines, leading to infammation or fbrosis, which in turn can damage vision. Results from studies have confirmed that mTOR is closely related to pterygium, age-related macular degeneration (AMD), glaucoma, cataract, diabetic retinopathy (DR), eye tumors and other eye diseases. Currently, mTOR inhibitors are widely used as immunosuppressants and approved for cancer treatment; however, there are few reports on the use of mTOR inhibitors for eye diseases. Therefore, in the article it provides a brief overview of the role, regulatory mechanisms, and drug treatment of the mTOR signaling pathway in related ophthalmic diseases, providing ideas for the pathological mechanisms and treatment of related ophthalmic diseases, in order to carry out more in-depth research in the future.
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。
