Objective: To investigate off-label ophthalmic medications, and provide an effective and safe evidence-based reference for the rational use of ophthalmic drugs. Methods: On the basis of collecting the off-label drug use recorded in 21 Aier Eye Hospital Group which including ophthalmic central cities and provincial capital level hospitals, and spot checking the prescription and doctor’s order drug use, this article conducted full demonstration and evaluation of off-label drug use which referred to the off-label drug used consensus of Guangdong and Shandong, and other literature on the off-label drug use in ophthalmology. The paper conducted statistics, analysis and induction, and solicited the opinions of relevant ophthalmology clinical experts. Results: Sorting out the evidence of the guides,consensus, journal papers and other evidence-based medicine in ophthalmic medication, recommending 8 items of level 1, 29 items of level 2, and 24 items of level 3, we compiled the “Reference catalogue for the off-label drug use in ophthalmic hospital (2021 edition)” within the group which can providing reference for clinical use. There were 61 off-label drugs commonly used in ophthalmology, involving 32 drugs. Among them, 32 items (52.5%) were used by over administration route, 13 items (21.3%) were used by over indication, and 14 items (23.0%) were used by over indication and administration route. Antibacterial drugs were the most frequently used in the varieties and items of off-label drug use, accounting for 13 (40.6%) and 26 (42.6%) respectively. Conclusion: Ophthalmic off-label medications are common owing to the special route of administration. Such as intraocular injection or eye drop have played a good role in the treatment of some ocular infectious diseases. Standardizing the off-label drug use of ophthalmology is an effective measure to reducing medical risks.

慢性移植物抗宿主病(chronic graft-versus-host disease，cGVHD)是骨髓移植后最具有破坏性并发症之一。移植物抗宿主病(graft-versus-host disease，GVHD)发生在10%~80%的造血干细胞移植(hematopoietic stem cell transplantation)受者中，而眼睛是人身体最脆弱的器官之一，有40%~60%接受HSCT的患者发生眼部GVHD，它主要影响泪腺、睑板腺、角膜和结膜等。cGVHD相关性干眼(dry eye associated with chronic graft-versus-host disease，cGVHD-DE)是眼部GVHD最多见的表现形式。cGVHD-DE的长期治疗因涉及多学科、多重结合治疗，至今仍然具有挑战性，其除了全身免疫抑制和眼部润滑剂外，通常还使用局部类固醇、环孢霉素和他克莫司滴眼液。针对中度和重度cGVHD-DE的治疗干预包括使用自体血清滴眼液和佩戴巩膜镜等，新兴起的治疗方案包括重链透明质酸 (heavy chain-hvaluronan/穿透素(pentraxin 3)结膜下注射、间充质基质细胞静脉注射、抑制纤维化药物等。

Chronic graft-versus-host disease (cGVHD) is one of the most devastating complications following bone marrow transplantation. GVHD develops in 10–80% of patients after hematopoietic stem cell transplantation (HSCT). The eye is one of the most vulnerable organs of the human body. Ocular GVHD occurs in 40–60% of patients with GVHD undergoing HSCT, and it mostly affects the lacrimal glands, meibomian glands, cornea, and conjunctiva. The most common form of ocular GVHD is dry eye disease (DED). The long-term treatment of cGVHD-related dry eye syndrome remains challenging and involves a multidisciplinary approach. Besides systemic immunosuppression and ocular lubricants, topical steroids, topical cyclosporine, and topical tacrolimus are commonly prescribed. Newer therapeutic interventions for moderate and severe cGVHD-related DED include using serum eye drops and scleral contact lenses. Emerging treatment options include subconjunctival injection of heavy chain-hyaluronan (HC-HA)/ pentraxin 3 (PTX3), intravenous injection of mesenchymal stromal cells, antifibrotic drugs, etc. This article reviews the mechanisms, clinical findings, and treatment of cGVHD-related dry eye syndrome.

高度近视(high myopia，HM)作为一种特殊类型的屈光型眼病，不仅会导致进行性、退行性眼底改变，其视神经损伤的患病率也很高。青光眼是全球范围内最常见的一种不可逆致盲性眼病，原发性开角型青光眼(primary open-angle glaucoma，POAG)是最常见的青光眼类型。近年来的研究发现HM与POAG的病理改变存在相似之处。由于HM眼底改变与早期POAG眼底改变容易混淆，HM患者早期发现POAG对延缓或阻止疾病进展很重要。HM患者长期随访不仅要观察黄斑病变，视神经形态与结构改变的观察也不容忽视。

As a special type of refractive eye disease, high myopia (HM) not only causes progressive and degenerative fundus changes, but also has a high prevalence of optic nerve damage. Glaucoma is the most common form of irreversible blinding eye diseases worldwide, among which, primary open-angle glaucoma (POAG) is the most common type. In recent studies, HM is found to have similarities on pathological changes as that of POAG. And HM fundus changes are easily confused with early stage POAG fundus changes; thus, the early detection of POAG on HM patients is highly important on disease deferment or prevention of disease progression. Macular degeneration as well as optic nerve morphology and structural changes are to be observed in the long-term follow-up for HM patients.

眼健康是国民健康的重要组成部分，包括盲在内的视觉损伤严重影响人民群众的身体健康和生活质量，加重家庭和社会负担，威胁社会经济生产活动，是涉及民生的重大公共卫生问题和社会问题。弱视作为幼儿期起病的主要视觉障碍性疾病之一，是致使青少年低视力的首要因素，影响青少年自身学业和心理健康，增加致盲风险，故做好弱视的预防及康复工作刻不容缓。通过梳理研究发现，国内外对弱视的传统治疗方法有遮盖疗法、屈光矫正、压抑疗法等，知觉学习、视功能训练、电子视频游戏、针灸等则是近年逐渐新兴起并被广泛运用的弱视康复治疗方法，近年来关于年龄对弱视康复治疗影响的相关研究也较多。通过整理前人研究成果，提出建立儿童青少年视力档案、建立五位一体弱视康复治疗布局模式、进行联合临床治疗青少年弱视的对策，以期为青少年弱视提供康复治疗手段参考和选择，促进青少年弱视康复治疗眼健康事业发展。

Eye health is an important part of national health. Visual impairment, including blindness, seriously affects people’s physical health and quality of life, increases the burden on families and society, threatens social and economic production activities, and is a major public health and social problem related to people’s livelihood. Amblyopia,as one of the main visual disorders in early childhood, is the primary factor causing low vision in adolescents, which affects their academic and mental health and increases the risk of blindness. Therefore, it is urgent to do a good job in the prevention and rehabilitation of amblyopia. By summarizing existing studies, it is found that traditional treatment methods for amblyopia at home and abroad include occlusion therapy, refractive correction, and depressive therapy, while perceptual learning, visual function training, electronic video games, acupuncture and so on are gradually emerging in recent years and widely used in recent years. There are numerous studies on the impact of age on the rehabilitation of amblyopia. By sorting out the previous research results, this paper puts forward the countermeasures of establishing visual acuity files for children and adolescents, establishing the five- in-one rehabilitation treatment layout model, and combining clinical treatment for adolescent amblyopia, in order to provide reference and choice for the rehabilitation treatment of adolescent amblyopia, and promote the development of the eye health cause of adolescent amblyopia rehabilitation.

Ahmed青光眼引流阀植入术作为难治性青光眼的主要治疗方案，能很大程度控制眼压，且疗效和预后均优于常规滤过性手术。但是远期引流盘周围被纤维包裹后会阻塞房水流出，引起术后高眼压，导致手术失败。因此，解决引流盘纤维包裹能很大程度地提高青光眼阀植入术后远期成功率，这也是目前的研究热点。目前临床上主要采用术前预防及术后二次操作对纤维包裹进行干预，但长期效果欠佳。本文就青光眼引流阀纤维包裹发生的组织病理学及分子机制、临床目前解决方案、前沿研究进展以及对Ahmed青光眼阀门的材料改造的探索进行综述。

Ahmed glaucoma valve implantation, as the main treatment option for refractory glaucoma, can control intraocular pressure (IOP) to a large extent. And its efficacy and prognosis are superior to those of conventional filtration surgery. IOP is well-controlled in the early postoperative stages. However, long-term fibrosis of encapsulated bleb inhibits fluid exchange and causes elevated IOP, leading to surgical failure. Therefore, treating fibrosis of encapsulated bleb can improve the long-term success rate after glaucoma valve implantation, which is also a research hotspot. Currently, the main clinical interventions are preoperative prophylaxis and postoperative secondary operations for fiber wrapping, but its long-term efficacy is not satisfactory. This article reviews the occurrence, histopathology and molecular mechanism of fibrous encapsulation, treatment in a clinical setting, cutting-edge research progress, and exploration on material modification of Ahmed glaucoma valve.
