    在过去的十年里,人工智能(AI)及其子领域,深度学习和机器学习,已经成为眼科不可或缺的一部分,尤其是在眼科成像领域。已经出现了各种各样的算法阵列以促进许多医学和外科视网膜状况的自动诊断。这些算法的发展需要使用大的视网膜图像数据集进行广泛的训练。这种方法显示出了有希望的影响,特别是在提高非专业临床医生对各种疾病的诊断准确性和远程医疗领域,眼科护理受到限制。并行,机器人技术在医疗领域取得了重大进展,包括眼科.机器人手术领域的绝大多数研究都集中在眼前节和玻璃体视网膜手术上。这些系统在准确性方面提供了潜在的改进,并解决了诸如手抖等问题。然而,广泛采用面临障碍,包括与这些系统相关的大量成本和外科医生陡峭的学习曲线。这些挑战目前限制了机器人手术系统在眼科中的更广泛实施。这篇小型评论讨论了当前的研究和挑战,强调人工智能和机器人系统在视网膜疾病领域的实施有限但不断增长。
    Over the past decade, artificial intelligence (AI) and its subfields, deep learning and machine learning, have become integral parts of ophthalmology, particularly in the field of ophthalmic imaging. A diverse array of algorithms has emerged to facilitate the automated diagnosis of numerous medical and surgical retinal conditions. The development of these algorithms necessitates extensive training using large datasets of retinal images. This approach has demonstrated a promising impact, especially in increasing accuracy of diagnosis for unspecialized clinicians for various diseases and in the area of telemedicine, where access to ophthalmological care is restricted. In parallel, robotic technology has made significant inroads into the medical field, including ophthalmology. The vast majority of research in the field of robotic surgery has been focused on anterior segment and vitreoretinal surgery. These systems offer potential improvements in accuracy and address issues such as hand tremors. However, widespread adoption faces hurdles, including the substantial costs associated with these systems and the steep learning curve for surgeons. These challenges currently constrain the broader implementation of robotic surgical systems in ophthalmology. This mini review discusses the current research and challenges, underscoring the limited yet growing implementation of AI and robotic systems in the field of retinal conditions.

    缺氧诱导因子(HIF)在调节细胞水平的氧敏感和适应中起着至关重要的作用。监督细胞氧稳态,红细胞产生,血管生成,和线粒体代谢.缺氧敏感性HIF-1α亚基促进组织适应缺氧条件,包括刺激促血管生成因子。早产儿视网膜病(ROP)是视网膜的增生性血管疾病,对早产儿童构成重大风险。如果未经治疗,ROP会导致视网膜脱离,严重的视力障碍,甚至失明。ROP的发病机制尚不完全清楚;然而,报告表明,早产导致未成熟的眼组织暴露于高水平的外源性氧气和高氧,增加活性氧的合成并抑制HIF的表达。在缺血期,缺氧敏感性视网膜中HIF-1α的表达受到刺激,导致促血管生成因子的过度产生和病理性新生血管的发展。鉴于HIF-1α在ROP发生发展中的重要作用,将其视为治疗策略的潜在分子靶标似乎是合理的.这篇综述使用PubMed、谷歌学者,和基地,重点关注HIF-1α在ROP发病机制中的作用及其作为新疗法靶点的潜力。
    Hypoxia-inducible factor (HIF) plays a crucial role in regulating oxygen sensing and adaptation at the cellular level, overseeing cellular oxygen homeostasis, erythrocyte production, angiogenesis, and mitochondrial metabolism. The hypoxia-sensitive HIF-1α subunit facilitates tissue adaptation to hypoxic conditions, including the stimulation of proangiogenic factors. Retinopathy of prematurity (ROP) is a proliferative vascular disease of the retina that poses a significant risk to prematurely born children. If untreated, ROP can lead to retinal detachment, severe visual impairment, and even blindness. The pathogenesis of ROP is not fully understood; however, reports suggest that premature birth leads to the exposure of immature ocular tissues to high levels of exogenous oxygen and hyperoxia, which increase the synthesis of reactive oxygen species and inhibit HIF expression. During the ischemic phase, HIF-1α expression is stimulated in the hypoxia-sensitive retina, causing an overproduction of proangiogenic factors and the development of pathological neovascularization. Given the significant role of HIF-1α in the development of ROP, considering it as a potential molecular target for therapeutic strategies appears justified. This review synthesizes information from the last six years (2018-2024) using databases such as PubMed, Google Scholar, and BASE, focusing on the role of HIF-1α in the pathogenesis of ROP and its potential as a target for new therapies.

    目的:这项研究的目的包括调整患者信息工具以满足whānau(大家庭)毛利人的需求,识别和审查提供的早产儿眼部检查视网膜病变(ROPEE)的书面信息,并确定ROPEE书面信息的改善。
    方法:ROPEE患者信息(印刷传单,网站,app)是从新西兰奥特罗阿(Aotearoa)的所有三级新生儿重症监护病房获得的。使用经过调整的“20个良好设计原则”指南对信息进行了审查,并给出了星级评定和Flesch-Kincaid可读性评分,以确定患者的可接受性和可用性。
    结果:对七个ROPEE信息材料进行了审查,并与经过调整的良好设计原则工具保持一致。基于适应的良好设计原则,在书面信息的许多方面确定了改进的机会,包括文字和语言,语气和意义,内容和设计。Flesch-Kincaid年级阅读分数的范围为12-22岁。书面资料也没有使用毛利语(Aotearoa土著语言)或广泛使用毛利语图像。
    结论:存在改善ROPEEwhānau信息的机会,包括使内容更具可读性,可理解和视觉上的吸引力。为Aotearoa全国优化ROPEE的临床信息将支持whānau决策,使书面信息与毛利人(奥特罗阿土著人民)保持一致是一个优先事项。
    OBJECTIVE: The aims of this research include adapting a patient information tool for whānau (extended family) Māori needs, identifying and reviewing written information provided for the retinopathy of prematurity eye examination (ROPEE) and identifying improvements to ROPEE written information.
    METHODS: ROPEE patient information (printed leaflets, website, app) was obtained from all tertiary neonatal intensive care units in Aotearoa New Zealand (Aotearoa). Information was reviewed using an adapted \"20 good-design principles\" guide and given a star rating and Flesch-Kincaid readability score to identify acceptability and usability for patients.
    RESULTS: Seven ROPEE information materials were reviewed and varied in alignment with the adapted good-design principles tool. Based on the adapted good-design principles, opportunities were identified in many aspects of the written information for improvement, including words and language, tone and meaning, content and design. The Flesch-Kincaid grade level reading scores ranged from 12-22 years reading age. Written information also did not use te reo Māori (Aotearoa Indigenous language) or extensively use Māori imagery.
    CONCLUSIONS: Opportunities exist to improve ROPEE whānau information, including making content more readable, understandable and visually appealing. Optimising the clinical information on ROPEE nationally for Aotearoa will support whānau decision making, and aligning written information with Māori (Indigenous peoples of Aotearoa) is a priority.

    背景:早产儿视网膜病变(ROP)是全球儿童失明的主要原因。及时的诊断和治疗在ROP管理中至关重要。因此,识别突出的风险因素可以促进立即采取行动。在各种危险因素中,分娩方式对ROP的影响尚不清楚.因此,本研究旨在评估不同分娩方式对ROP发生率的相关性.
    方法:在PubMed上进行了全面的文献检索,ProQuest,EBSCOHost和Cochrane数据库,评估从开始到2023年12月的分娩方式-阴道分娩或剖宫产(剖腹产)-ROP发生率之间的关系。进行随机效应荟萃分析以估计合并的OR及其95%CI。
    结果:本综述包括5项队列研究,涉及2048名婴儿。与剖腹产相比,通过阴道分娩出生的婴儿的ROP发生率更高。荟萃分析显示,剖腹产使ROP婴儿的未调整几率降低了46%,异质性低(OR0.54(95%CI0.40至0.73);I2=40.73%)。然而,合并校正效应在中度异质性下统计学上无统计学意义(校正OR0.59(95%CI0.28至1.23);I2=70.51%),可能源于每个研究的控制变量的多种变化。
    结论:尽管有不同的统计学意义,我们的研究结果强调了理解分娩方式对新生儿眼科结局的影响的迫切需要.由于现有研究数量有限,需要进一步的研究来确认这种关联。

    BACKGROUND: Retinopathy of prematurity (ROP) is a leading cause of childhood blindness worldwide. Prompt diagnosis and treatment are crucial in ROP management. Thus, the identification of prominent risk factors could facilitate immediate action. Among various risk factors, the effects of mode of delivery on ROP remain unclear. Therefore, this study aims to assess the association between different modes of delivery on ROP incidence.
    METHODS: Comprehensive literature search was conducted on PubMed, ProQuest, EBSCOHost and Cochrane databases, to evaluate the association of mode of delivery-vaginal delivery or caesarean section (c-section)-and the incidence of ROP from inception to December 2023. Random-effects meta-analysis was performed to estimate the pooled OR along with their 95% CIs.
    RESULTS: This review included 5 cohort studies involving 2048 babies. A higher incidence of ROP was observed in infants born through vaginal delivery compared with caesarean section. Meta-analysis showed that C-section decreased the unadjusted odds of having ROP infants by 46% with low heterogeneity (OR 0.54 (95% CI 0.40 to 0.73); I2=40.73%). However, pooled adjusted effects were statistically insignificant with moderate heterogeneity (adjusted OR 0.59 (95% CI 0.28 to 1.23); I2=70.51%), possibly stemming from multiple variations in the controlled variables of each study.
    CONCLUSIONS: Despite varying statistical significance, our findings underscore the crucial need to comprehend the influence of delivery mode on neonatal ophthalmic outcomes. Due to a limited number of existing studies, further research is needed to confirm the association.
    UNASSIGNED: CRD42023486278.

    早产儿视网膜病变(ROP)是由早产儿血管异常增殖引起的视网膜病变。它可以导致视网膜脱离,在严重的情况下,失明,渲染ROP的临界条件。新生儿医学的进步提高了低出生体重和低胎龄婴儿的存活率。然而,这一进展也导致了ROP发病率的上升.目前,早产,低出生体重和高产后氧水平是ROP的独立危险因素。其他因素包括交付方式,多胎,贫血,输血,孕产妇怀孕因素,新生儿支气管肺发育不良,使用表面活性剂,动脉导管动脉和坏死性小肠结肠炎。早产儿的实验室指标,如血小板计数,血糖水平,炎症细胞,血脂、血红蛋白和输血也可能与ROP有关。然而,ROP的病因和发病机制尚不完全清楚。许多因素可能影响ROP的发生和进展,包括血小板计数减少,血红蛋白水平下降,白细胞计数增加,血糖水平升高,和脂质代谢紊乱。本研究综述了血小板计数的影响,血红蛋白,血糖,炎症细胞和因子,血脂,和血浆代谢途径对ROP的影响。
    Retinopathy of prematurity (ROP) is a retinopathy caused by abnormal proliferation of blood vessels in premature infants. It can lead to retinal detachment and, in severe cases, blindness, rendering ROP a critical condition. Advances in neonatal medicine have improved survival rates of low birth weight and low gestational age infants. However, this progress has also led to a rise in incidence of ROP. Currently, premature birth, low birth weight and high postpartum oxygen levels are independent risk factors for ROP. Other factors include mode of delivery, multiple births, anemia, blood transfusion, maternal pregnancy factors, neonatal bronchopulmonary dysplasia, use of surfactants, arterial ductus arteriosus and necrotizing enterocolitis. Laboratory indicators in premature infants such as platelet count, levels of blood glucose, inflammatory cells, lipid and hemoglobin and blood transfusion may also be associated with ROP. However, the etiology and pathogenesis of ROP are not fully understood. A number of factors may influence the onset and progression of ROP, including decreased platelet counts, decreased hemoglobin levels, increased white blood cell counts, increased blood glucose levels, and disorders of lipid metabolism. The present study reviewed the effects of platelet count, hemoglobin, blood glucose, inflammatory cells and factors, blood lipids, and plasma metabolic pathways on ROP.

    背景:眼皮肤白化病(OCA)是一组影响黑色素生物合成的常染色体隐性遗传性疾病,导致头发异常,皮肤,和眼睛。早产儿视网膜病变(ROP)是一种增殖性视网膜病变,主要见于低出生体重和胎龄较早的早产儿。但它也会影响足月婴儿或体重正常的儿童,特别是在发展中国家。ROP和OCA的共存是罕见的。关于治疗方法的文件有限,由于缺乏黑色素,很少有研究报告激光治疗的积极结果。这项研究讨论了诊断为ROP和OCA的女婴的治疗挑战,并强调了遗传分析在指导这种罕见的合并症的治疗决策中的重要性。
    方法:本研究报告1例ROP与OCA同时发生。基因检测显示两种变异,c.727C>T(p。R243C)和c.1832T>C(p。L611P),在OCA2基因中,从病人的母亲和父亲那里继承下来,分别。鉴定的突变与OCA2的诊断一致,被分类为OCA的亚型。患者最初接受玻璃体内注射抗血管内皮生长因子(抗VEGF),然后是激光光凝治疗复发事件.在2个月的随访期间观察到良好的结果。
    结论:ROP和OCA的同时出现是一种罕见的现象,这是中国人口中记录的第一例。当前病例支持使用激光作为部分色素沉着受损的OCA2患者ROP的主要治疗方式。此外,遗传分析可以帮助预测该患者人群中激光光凝的有效性.
    BACKGROUND: Oculocutaneous albinism (OCA) is a group of autosomal recessive hereditary disorders that affect melanin biosynthesis, resulting in abnormalities in hair, skin, and eyes. Retinopathy of prematurity (ROP) is a proliferative retinopathy mainly observed in premature infants with low birth weight and early gestational age, but it can also affect full-term infants or children with normal weight, particularly in developing countries. The coexistence of ROP and OCA is rare. There is limited documentation regarding treatment approaches, with few studies reporting positive outcomes with laser treatment due to the absence of melanin pigment. This study discusses the treatment challenges in a female infant diagnosed with ROP and OCA, and underscores the importance of genetic analysis in guiding therapeutic decisions for this rare comorbid condition.
    METHODS: The study presents a case of ROP occurring concurrently with OCA. Genetic testing revealed two variants, c.727C > T (p.R243C) and c.1832 T > C (p.L611P), in the OCA2 gene, inherited from the patient\'s mother and father, respectively. The identified mutations were consistent with a diagnosis of OCA2, classified as a subtype of OCA. The patient initially received intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection, followed by laser photocoagulation therapy for a recurrent event. A favorable outcome was observed during the 2-month follow-up period.
    CONCLUSIONS: The co-occurrence of ROP and OCA is a rare phenomenon, and this is the first recorded case in the Chinese population. The current case supports the use of laser as the primary treatment modality for ROP in OCA2 patients with partial pigmentation impairment. Furthermore, genetic analysis can aid in predicting the effectiveness of laser photocoagulation in this patient population.

  • 文章类型: Systematic Review
    早产儿视网膜病是全球儿童失明的重要原因。这项研究旨在鉴定与ROP发展相关的血清生物标志物。
    使用PRISMA指南进行系统评价和荟萃分析。搜索了三个数据库(Pubmed,Scopus和WebofScience)从2003年到2023年3月。仅包括调查早产儿(<37孕周)血清生物标志物水平的研究。
    荟萃分析表明,低血清IGF-1水平与ROP[SMD(95%CI)-0.46[-.63,-.30]的发展有很强的关联,p<.001]。荟萃分析表明,较高的血清葡萄糖水平与ROP的发展有关[SMD(95%CI)为1.25[.94,1.55],p<.001]。Meta分析提示血小板减少与ROP[SMD(95%CI)-0.62[-.86,-.37]的发展有关,p<.001]。
    低水平的血清IGF-1,高水平的血清葡萄糖和血小板减少症似乎都与本综述中研究的63种生物标志物中的ROP的发展具有最强的关联。这些关联凸显了它们在ROP中作为诊断生物标志物的潜在用途,尽管需要进一步的研究来确定这些生物标志物与疾病发病机理之间的确切关系。
    UNASSIGNED: Retinopathy of prematurity is a significant global cause of childhood blindness. This study aims to identify serum biomarkers that are associated with the development of ROP.
    UNASSIGNED: A systematic review and meta-analysis was conducted using PRISMA guidelines. Three databases were searched (Pubmed, Scopus and Web of Science) from 2003 to March 2023. Only studies investigating serum biomarker levels in preterm infants (<37 weeks gestation) were included.
    UNASSIGNED: Meta-analysis suggests that low serum IGF-1 levels have a strong association with the development of ROP [SMD (95% CI) of -.46 [-.63, -.30], p < .001]. Meta-analysis suggests that higher serum glucose levels were associated with the development of ROP [SMD (95% CI) of 1.25 [.94, 1.55], p < .001]. Meta-analysis suggests that thrombocytopenia is associated with the development of ROP [SMD (95% CI) of -.62 [-.86, -.37], p < .001].
    UNASSIGNED: Low levels of serum IGF-1, high levels of serum glucose and thrombocytopenia all appear to have the strongest association with the development of ROP out of the 63 biomarkers investigated in this review. These associations highlight their potential use as diagnostic biomarkers in ROP, though further research is needed to establish the exact relationship between these biomarkers and disease pathogenesis.

    巨噬细胞是先天免疫系统的重要组成部分,它们的激活对于免疫和炎症过程的各个方面都是必不可少的,组织修复,维持身体状态的平衡。巨噬细胞存在于所有眼组织中,从前表面跨越,包括角膜,到后极点,以脉络膜/巩膜为代表。神经视网膜也由称为小胶质细胞的专门驻留巨噬细胞组成。小胶质细胞/巨噬细胞的可塑性使它们能够根据组织微环境的变化采取不同的激活状态。当暴露于各种因素时,小胶质细胞/巨噬细胞分化为不同的表型,每个人都表现出独特的特征和角色。此外,大量研究表明,小胶质细胞/巨噬细胞极化与各种眼内疾病的发展和逆转密切相关.本文综述了小胶质细胞/巨噬细胞极化与眼部病理过程(包括自身免疫性葡萄膜炎,视神经炎,交感性眼炎,视网膜色素变性,青光眼,增生性玻璃体视网膜病变,视网膜下纤维化,葡萄膜黑色素瘤,缺血性视神经病变,早产儿视网膜病变和脉络膜新生血管)。还讨论了小胶质细胞/巨噬细胞极化在早产儿视网膜病中的矛盾作用。一些研究表明小胶质细胞/巨噬细胞参与眼部疾病的病理学。然而,需要进一步探索相关机制和监管程序。小胶质细胞/巨噬细胞极化所显示的功能多样性与眼内疾病的关系可能为眼内疾病的治疗提供新的方向。
    Macrophages form a crucial component of the innate immune system, and their activation is indispensable for various aspects of immune and inflammatory processes, tissue repair, and maintenance of the balance of the body\'s state. Macrophages are found in all ocular tissues, spanning from the front surface, including the cornea, to the posterior pole, represented by the choroid/sclera. The neural retina is also populated by specialised resident macrophages called microglia. The plasticity of microglia/macrophages allows them to adopt different activation states in response to changes in the tissue microenvironment. When exposed to various factors, microglia/macrophages polarise into distinct phenotypes, each exhibiting unique characteristics and roles. Furthermore, extensive research has indicated a close association between microglia/macrophage polarisation and the development and reversal of various intraocular diseases. The present article provides a review of the recent findings on the association between microglia/macrophage polarisation and ocular pathological processes (including autoimmune uveitis, optic neuritis, sympathetic ophthalmia, retinitis pigmentosa, glaucoma, proliferative vitreoretinopathy, subretinal fibrosis, uveal melanoma, ischaemic optic neuropathy, retinopathy of prematurity and choroidal neovascularization). The paradoxical role of microglia/macrophage polarisation in retinopathy of prematurity is also discussed. Several studies have shown that microglia/macrophages are involved in the pathology of ocular diseases. However, it is required to further explore the relevant mechanisms and regulatory processes. The relationship between the functional diversity displayed by microglia/macrophage polarisation and intraocular diseases may provide a new direction for the treatment of intraocular diseases.

    Preterm birth remains a significant global health concern as it can lead to various health complications and long-term developmental challenges. Early nutrition intervention plays a crucial role in optimizing the growth, development, and overall health outcomes of premature infants. This review aims to summarize and analyze the existing literature regarding the effect of early nutrition interventions on premature babies. A comprehensive search was conducted through various electronic databases, including PubMed, Scopus, and Google Scholar, focusing on nutrition interventions specifically targeting premature infants. The review highlights the benefits of early nutrition interventions, including enteral and parenteral feeding, human milk, and the provision of specific nutrients. These interventions have been shown to enhance growth rates, promote neurodevelopmental outcomes, reduce the incidence and severity of retinopathy of prematurity (ROP), reduce the risk of infection, and improve overall morbidity and mortality rates in premature babies. Overall, the findings from this review suggest that early nutrition interventions have a positive impact on the health and developmental outcomes of premature babies. However, further research is required to determine the optimal approaches, optimal timing, and long-term effects of various interventions. Collaboration between healthcare providers, researchers, and families is crucial in implementing evidence-based nutrition practices and supporting the growth and development of premature infants.

    人工智能(AI)已成为快速发展的眼科领域的研究重点。然而,该领域缺乏对人工智能健康经济学的系统研究。这篇综述考察了来自PubMed的研究,谷歌学者,和采用定量分析的Web数据库,直到2023年7月。大多数研究表明,人工智能可以节省成本并提高眼科效率。另一方面,一些研究表明,在医疗保健中使用人工智能可能会增加患者的成本,特别是考虑到劳动力成本等因素时,基础设施,和患者的依从性。未来的研究应该涵盖更广泛的眼科疾病,而不是常见的眼部疾病。此外,开展广泛的卫生经济研究,旨在收集与其自身环境相关的数据,对于中国来说,促进人工智能在国内的临床实施是当务之急。
    Artificial Intelligence (AI) has become a focus of research in the rapidly evolving field of ophthalmology. Nevertheless, there is a lack of systematic studies on the health economics of AI in this field. We examine studies from the PubMed, Google Scholar, and Web of Science databases that employed quantitative analysis, retrieved up to July 2023. Most of the studies indicate that AI leads to cost savings and improved efficiency in ophthalmology. On the other hand, some studies suggest that using AI in healthcare may raise costs for patients, especially when taking into account factors such as labor costs, infrastructure, and patient adherence. Future research should cover a wider range of ophthalmic diseases beyond common eye conditions. Moreover, conducting extensive health economic research, designed to collect data relevant to its own context, is imperative.
