The eye provides novel insights into general health, as well as pathogenesis and development of systemic diseases. In the past decade, growing evidence has demonstrated that the eye's structure and function mirror multiple systemic health conditions, especially in cardiovascular diseases, neurodegenerative disorders, and kidney impairments. This has given rise to the field of oculomics-the application of ophthalmic biomarkers to understand mechanisms, detect and predict disease. The development of this field has been accelerated by three major advances: 1) the availability and widespread clinical adoption of high-resolution and non-invasive ophthalmic imaging (“hardware”); 2) the availability of large studies to interrogate associations (“big data”); 3) the development of novel analytical methods, including artificial intelligence (AI) (“software”). Oculomics offers an opportunity to enhance our understanding of the interplay between the eye and the body, while supporting development of innovative diagnostic, prognostic, and therapeutic tools. These advances have been further accelerated by developments in AI, coupled with large-scale linkage datasets linking ocular imaging data with systemic health data. Oculomics also enables the detection, screening, diagnosis, and monitoring of many systemic health conditions. Furthermore, oculomics with AI allows prediction of the risk of systemic diseases, enabling risk stratification, opening up new avenues for prevention or individualized risk prediction and prevention, facilitating personalized medicine. In this review, we summarise current concepts and evidence in the field of oculomics, highlighting the progress that has been made, remaining challenges, and the opportunities for future research.
眼睛为一般健康以及全身性疾病的发病机制和发展提供了新的见解。在过去的十年中,越来越多的证据表明,眼睛的结构和功能反映了多种全身健康状况,特别是在心血管疾病、神经退行性疾病和肾脏损伤中。这导致了眼组学领域的兴起-应用眼科生物标志物来了解机制,检测和预测疾病。这一领域的发展被三个主要进展所加速:1)高分辨率和非侵入性眼科成像(“硬件”)的可用性和广泛的临床采用;2)大型研究的可用性(“大数据”);3)新型分析方法的发展,包括人工智能(AI)(“软件”)。眼组学提供了一个机会来加强我们对眼睛和身体之间相互作用的理解,同时支持创新诊断、预后和治疗工具的发展。人工智能的发展,加上将眼部成像数据与系统健康数据联系起来的大规模链接数据集,进一步加速了这些进步。眼组学还可以检测、筛选、诊断和监测许多全身健康状况。此外,人工智能的经济学可以预测全身性疾病的风险,实现风险分层,开辟新的预防途径或个性化风险预测和预防,促进个性化医疗。在这篇综述中,我们总结了目前在经济学领域的概念和证据,强调了已经取得的进展,仍然存在的挑战,以及未来研究的机会。

Tear fluid is an emerging source of disease biomarkers, drawing attention due to its quick, inexpensive, and non-invasive collection. The advancements in detection techniques enable the measurement of ultra-low biomarker levels from small sample volumes typical of tear fluid. The lack of standardized protocols for collection, processing, and analysis of tear fluid remains a significant challenge. To address this, we convened the Tear Research Network Review Taskforce in 2022 to review protocols from the past three decades, providing a comprehensive overview of the methodologies used in tear fluid biomarker research.
A total of 1484 articles published from January 1974 to May 2024 from two electronic databases, Embase and Ovid MEDLINE, were reviewed. An exponential increase in the number of articles on tear fluid biomarkers was observed from 2015 onwards. The two most commonly reported collection methods were; glass capillaries (45.2%), and Schirmer's strips (25%), with glass capillary tube collection remaining the most frequent method until 2019, when Schirmer's strips became the leading method. Most articles analyzed tear fluid proteins (65%) and focused on a single analyte (32.3%). In recent years, an increase was observed in the type and number of examined analytes.
The differences in the reported methodologies and protocols underscore the need for standardization and harmonization within the field of tear fluid biomarkers to minimize methodological differences and reduce variability in clinical outcomes. Consistent and detailed reporting is essential for improving the reproducibility and validity of tear fluid studies, in order to advance their potential clinical applications.
泪液是一种新兴的疾病生物标志物来源,因其快速、廉价和无创收集而备受关注。检测技术的进步使得从典型泪液的小样本量中测量超低生物标志物水平成为可能。缺乏收集、处理和分析泪液的标准化方案仍然是一个重大挑战。为了解决这一问题,我们于2022年召集了泪液研究网络审查工作组,对过去三十年的协议进行审查,全面概述泪液生物标志物研究中使用的方法。对1974年1月至2024年5月在Embase和Ovid MEDLINE两个电子数据库中发表的1484篇文章进行了综述。从2015年起,关于泪液生物标志物的文章数量呈指数增长。最常见的两种收集方法是;玻璃毛细管采集(45.2%)和席尔默试纸(25%),其中玻璃毛细管采集一直是最常用的方法,直到2019年,席尔默试纸成为主要方法。大多数文章分析泪液蛋白(65%),集中于单一分析物(32.3%)。近年来,检测分析物的种类和数量都有所增加。所报告的方法和方案的差异强调了泪液生物标志物领域内标准化和协调的必要性,以尽量减少方法差异并减少临床结果的可变性。一致和详细的报告对于提高泪液研究的可重复性和有效性至关重要,以促进其潜在的临床应用。

Background

AI-powered image generation technology holds the potential to reshape medical practice, yet it remains an unfamiliar technology for both medical researchers and clinicians alike. Given the adoption of this technology relies on clinician understanding and acceptance, we sought to demystify its use in ophthalmology. To this end, we present a literature review on image generation technology in ophthalmology, examining both its theoretical applications and future role in clinical practice.

Methods

First, we consider the key model designs used for image synthesis, including generative adversarial networks, autoencoders, and diffusion models. We then perform a survey of the literature for image generation technology in ophthalmology prior to September 2024, presenting both the type of model used and its clinical application. Finally, we discuss the limitations of this technology, the risks of its misuse and the future directions of research in this field.

Results

Applications of this technology include improving AI diagnostic models, inter-modality image transformation, more accurate treatment and disease prognostication, image denoising, and individualised education. Key barriers to its adoption include bias in generative models, risks to patient data security, computational and logistical barriers to development, challenges with model explainability, inconsistent use of validation metrics between studies and misuse of synthetic images. Looking forward, researchers are placing a further emphasis on clinically grounded metrics, the development of image generation foundation models and the implementation of methods to ensure data provenance.

Conclusion

Compared to other medical applications of AI, image generation is still in its infancy. Yet, it holds the potential to revolutionise ophthalmology across research, education and clinical practice. This review aims to guide ophthalmic researchers wanting to leverage this technology, while also providing an insight for clinicians on how it may change ophthalmic practice in the future.
背景:人工智能驱动的图像生成技术有可能极大地重塑眼科临床实践。这项技术的采用有赖于临床医生的接受程度,但对于眼科研究人员和临床医生来说,这是一项陌生的技术。在这项工作中,我们对图像生成技术在眼科中的应用进行了文献综述,讨论了其理论应用和未来作用:首先,我们探讨了用于图像合成的主要模型设计,包括生成式对抗网络、自动编码器和扩散模型。然后,我们对 2024 年 9 月之前眼科图像生成技术的文献进行了调查,收集了每项研究使用的模型类型及其临床应用。最后,我们讨论了这项技术的局限性、滥用的风险以及该领域未来的研究方向:结果:该技术的应用包括提高诊断模型性能、跨模态图像转换、治疗和疾病预后、图像去噪和教育。将这一技术融入眼科临床实践的主要挑战包括生成模型的偏差、患者数据安全风险、模型开发的计算和后勤障碍、模型可解释性的挑战、不同研究之间使用的验证指标不一致以及合成图像的滥用。展望未来,研究人员将进一步强调临床基础指标、图像生成基础模型的开发以及确保数据来源的方法的实施:显而易见,图像生成技术有可能为眼科领域的许多任务带来益处,但与人工智能的其他医疗应用相比,它仍处于起步阶段。本综述旨在帮助眼科研究人员确定最佳模型和方法,以便更好地利用这项技术。

The neuroimmune interface in retinal regeneration 视网膜再生中的神经免疫界面
IF 18.6 1区 医学 Q1 OPHTHALMOLOGY Pub Date : 2025-05-01 Epub Date: 2025-04-24 DOI: 10.1016/j.preteyeres.2025.101361

Retinal neurodegeneration leads to irreversible blindness due to the mammalian nervous system's inability to regenerate lost neurons. Efforts to regenerate retina involve two main strategies: stimulating endogenous cells to reprogram into neurons or transplanting stem-cell derived neurons into the degenerated retina. However, both approaches must overcome a major barrier in getting new neurons to grow back down the optic nerve and connect to appropriate visual targets in environments that differ significantly from developmental conditions. While immune privilege has historically been associated with the central nervous system, an emerging literature highlights the active role of immune cells in shaping neurodegeneration and regeneration. This review explores the neuroimmune interface in retinal repair, dissecting how immune interactions influence glial reprogramming, transplantation outcomes, and axonal regeneration. By integrating insights from regenerative species with mammalian models, we highlight novel immunomodulatory strategies to optimize retinal regeneration.
由于哺乳动物的神经系统无法再生失去的神经元,视网膜神经变性会导致不可逆的失明。视网膜再生包括两种主要策略:刺激内源性细胞重编程为神经元或将干细胞来源的神经元移植到退化的视网膜中。然而,这两种方法都必须克服一个主要障碍,使新的神经元沿着视神经生长,并在与发育条件明显不同的环境中连接到适当的视觉目标。虽然免疫特权历来与中枢神经系统有关,但新兴文献强调了免疫细胞在形成神经变性和再生中的积极作用。这篇综述探讨了视网膜修复中的神经免疫界面,解剖了免疫相互作用如何影响神经胶质重编程、移植结果和轴突再生。通过整合再生物种与哺乳动物模型的见解,我们强调了优化视网膜再生的新免疫调节策略。

Animal models for the evaluation of retinal stem cell therapies 评估视网膜干细胞治疗的动物模型

Retinal degeneration (RD) diseases leading to severe vision loss can affect photoreceptors (PRs) that are responsible for phototransduction, or retinal pigmented epithelium (RPE) providing support for PRs. Human pluripotent stem cell (hPSC)-based therapies are a potential approach for restoration of retinal structure in patients with currently incurable RD diseases. Currently, there are two targeted hPSC therapeutics: PR rescue and PR replacement. PR rescue involves the transplantation of RPE or other neural progenitors into the subretinal space to slow down or prevent further RD. RPE transplantation plays a critical role in preserving photoreceptors by providing trophic support and maintaining retinal integrity, particularly in diseases like age-related macular degeneration (AMD). Advances in RPE transplantation methods, such as polarized monolayer cultures and scaffold-based approaches, have shown promise in enhancing graft survival and integration. However, limitations include inconsistent integration, variable neurotrophic factor secretion, and immune rejection risks in non-autologous transplants. In PR replacement, stem cell-derived photoreceptor-like cells or photoreceptor progenitors (PRP) obtained are transplanted into the eye. While PRPs are commonly obtained from retinal organoids (ROs), alternative sources, such as early differentiation stages or direct differentiation protocols, are also utilized to enhance the efficiency and scalability of PRP generation. Challenges include achieving proper integration, forming outer segments, rosette formation, and avoiding immune rejection or tumorigenicity. Various animal models that simulate human RD diseases are being used for establishing surgical feasibility, graft survival and visual functional recovery but fail to replicate clinical immune challenges. Rodent models lack macula-like structures and have limited reliability in detecting subtle functional changes, while larger animal models pose ethical, logistical, and financial challenges. Immunocompromised models have been developed for minimizing xenograft issues. Visual functional testing for efficacy includes optokinetic testing (OKN), electroretinography (ERG), and electrophysiological recordings from the retina and brain. These tests often fail to capture the complexity of human visual recovery, highlighting the need for advanced models and improved functional testing techniques. This review aims to aggregate current knowledge about approaches to stem cell transplantation, requirements of animal models chosen for validating vision benefits of transplantation studies, advantages of using specific disease models and their limitations. While promising strides have been made, addressing these limitations remains essential for translating stem cell-based therapies into clinical success.
视网膜变性(RD)疾病导致严重的视力丧失,可影响负责光传导的光感受器(PRs)或为PRs提供支持的视网膜色素上皮(RPE)。基于人类多能干细胞(hPSC)的治疗是目前无法治愈的RD疾病患者视网膜结构修复的潜在方法。目前,有两种靶向hPSC治疗方法:PR挽救和PR替代。PR救援包括将RPE或其他神经祖细胞移植到视网膜下空间,以减缓或防止进一步的RD。RPE移植通过提供营养支持和维持视网膜完整性,在保护光感受器方面起着关键作用,特别是在年龄相关性黄斑变性(AMD)等疾病中。RPE移植方法的进展,如极化单层培养和基于支架的方法,已经显示出增强移植物存活和整合的希望。然而,局限性包括不一致的整合,可变的神经营养因子分泌,以及非自体移植的免疫排斥风险。在PR置换中,获得的干细胞衍生的光感受器样细胞或光感受器祖细胞(PRP)被移植到眼睛中。虽然PRP通常从视网膜类器官(ROs)中获得,但其他来源,如早期分化阶段或直接分化协议,也被用于提高PRP生成的效率和可扩展性。挑战包括实现适当的整合,形成外节段,玫瑰花结形成,以及避免免疫排斥或致瘤性。各种模拟人类RD疾病的动物模型被用于确定手术可行性、移植物存活和视觉功能恢复,但无法复制临床免疫挑战。啮齿动物模型缺乏黄斑样结构,在检测细微功能变化方面可靠性有限,而大型动物模型则面临伦理、后勤和财务方面的挑战。免疫功能低下的模型已经开发,以尽量减少异种移植物的问题。疗效的视功能测试包括光动力学测试(OKN)、视网膜电图(ERG)和视网膜和大脑的电生理记录。这些测试往往无法捕捉到人类视觉恢复的复杂性,因此需要先进的模型和改进的功能测试技术。本综述旨在汇总目前关于干细胞移植方法的知识,验证移植研究的视力益处所选择的动物模型的要求,使用特定疾病模型的优势及其局限性。虽然已经取得了可喜的进展,但解决这些限制仍然是将干细胞疗法转化为临床成功的关键。

The visual chromophore 11-cis-retinal (11cRAL) is essential to vertebrate phototransduction and therefore, must be regenerated so vision can be sustained. 11cRAL regeneration mediated by the classical visual cycle is insufficient under photopic conditions. Expressed in the retinal pigment epithelium (RPE) and Müller glia, the retinal G protein-coupled receptor (RGR) can act as an alternative visual cycle photoisomerase, photogenerating 11cRAL in bright light conditions. While named a G protein-coupled receptor, RGR has no known coupled G protein. In the photoisomerase process, RGR bound all-trans-retinal (atRAL) is converted to 11cRAL. Here, we review how this core reaction integrates into RPE and Müller cell visual cycles. Significantly, mutations in human RGR are associated with inherited retinal degeneration and age-related macular degeneration, ocular diseases impairing vision. In this article, we comprehensively review 30 years of research into this membrane-bound protein, to comprehend RGR's i) biological role in vision, ii) association with ocular disease, iii) and surprising role in non-ocular function and disease. We discuss studies with opposing views on the proposed role of RGR as mediating a non-canonical visual cycle which photogenerates 11cRAL. We highlight knowledge gaps that current RGR research is addressing.
视觉发色团 11-顺式视网膜(11cRAL)对脊椎动物的光传导至关重要,因此必须再生才能维持视觉。在光照条件下,由经典视觉周期介导的 11cRAL 再生是不充分的。视网膜 G 蛋白偶联受体(RGR)在视网膜色素上皮细胞(RPE)和缪勒神经胶质细胞中表达,可作为另一种视觉循环光异构酶,在强光条件下光生成 11cRAL。虽然被命名为 G 蛋白偶联受体,但 RGR 并没有已知的偶联 G 蛋白。在光异构酶过程中,与 RGR 结合的全反式视网膜(atRAL)会转化为 11cRAL。在此,我们回顾了这一核心反应是如何融入 RPE 和 Müller 细胞视觉循环的。值得注意的是,人类 RGR 基因突变与遗传性视网膜变性和老年性黄斑变性这些损害视力的眼部疾病有关。在本文中,我们全面回顾了 30 年来对这种膜结合蛋白的研究,以了解 RGR 的 i) 在视觉中的生物学作用,ii) 与眼部疾病的关联,iii) 以及在非眼部功能和疾病中的惊人作用。我们讨论了关于 RGR 在介导非经典视觉循环(光生成 11cRAL)中的作用的研究,这些研究观点截然相反。我们强调了当前 RGR 研究正在解决的知识空白。

Astronauts can develop a distinct collection of neuro-ophthalmic findings during long duration spaceflight, collectively known as Spaceflight Associated Neuro-ocular Syndrome (SANS). These clinical characteristics include optic disc edema, hyperopic refractive shifts, globe flattening, and chorioretinal folds, which may pose a health risk for future space exploration. Obtaining knowledge of SANS and countermeasures for its prevention is crucial for upcoming crewed space missions and warrants a multidisciplinary approach. This review examines the potential causes and countermeasures of SANS, including space anticipation glasses, lower body negative pressure, venoconstrictive thigh cuffs, impedance threshold devices, translaminar pressure gradient modulation, centrifugation, artificial gravity, pharmaceuticals, and precision nutritional supplementation. This paper highlights future research directions for understanding the genetic, anthropometric, behavioral, and environmental susceptibilities to SANS as well as how to use terrestrial analogs for testing future mitigation strategies.

The Bruch's membrane (BM) is an acellular, extracellular matrix that lies between the choroid and retinal pigment epithelium (RPE). The BM plays a critical role in retinal health, performing various functions including biomolecule diffusion and RPE support. The BM is also involved in many retinal diseases, and insights into BM dysfunction allow for further understanding of the pathophysiology of various chorioretinal pathologies. Thus, characterization of the BM serves as an important area of research to further understand its involvement in retinal disease. In this article, we provide a review of various advancements in characterizing and visualizing the BM. We provide an overview of the BM in retinal health, as well as changes observed in aging and disease. We then describe current state-of-the-art imaging modalities and advances to further visualize the BM including various types of optical coherence tomography imaging, near-infrared reflectance (NIR), and autofluorescence imaging and tissue matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS). Following advances in imaging of the BM, we describe animal, cellular, and synthetic models that have been developed to further visualize the BM. Following this section, we provide an overview of deep learning in retinal imaging and describe advances in computational and artificial intelligence (AI) techniques to provide automated segmentation of the BM and BM opening. We conclude this section considering the clinical implications of these segmentation techniques. Ultimately, the diverse advances aimed to further characterize the BM may allow for deeper insights into the involvement of this critical structure in retinal health and disease.
布鲁氏膜(BM)是一种位于脉络膜和视网膜色素上皮(RPE)之间的细胞外基质。BM在视网膜健康中起着至关重要的作用,发挥着包括生物分子扩散和RPE支持在内的各种功能。基底膜也与许多视网膜疾病有关,对基底膜功能障碍的了解有助于进一步了解各种视网膜病理的病理生理学。因此,BM的表征是进一步了解其在视网膜疾病中的作用的一个重要研究领域。在本文中,我们提供了各种进展的回顾表征和可视化BM。我们提供了视网膜健康的BM的概述,以及在衰老和疾病中观察到的变化。然后,我们描述了当前最先进的成像方式和进一步可视化BM的进展,包括各种类型的光学相干断层成像,近红外反射(NIR),自体荧光成像和组织基质辅助激光解吸/电离成像质谱(MALDI-IMS)。随着脑基成像的进展,我们描述了动物、细胞和合成模型,这些模型已经开发出来,可以进一步可视化脑基。在本节之后,我们概述了视网膜成像中的深度学习,并描述了计算和人工智能(AI)技术的进展,以提供BM和BM开口的自动分割。我们总结本节考虑到这些分割技术的临床意义。最终,旨在进一步表征基底膜的各种进展可能会让我们更深入地了解这一关键结构在视网膜健康和疾病中的作用。

Müller cells are a crucial retinal cell type involved in multiple regulatory processes and functions that are essential for retinal health and functionality. Acting as structural and functional support for retinal neurons and photoreceptors, Müller cells produce growth factors, regulate ion and fluid homeostasis, and facilitate neuronal signaling. They play a pivotal role in retinal morphogenesis and cell differentiation, significantly contributing to macular development.
Due to their radial morphology and unique cytoskeletal organization, Müller cells act as optical fibers, efficiently channeling photons directly to the photoreceptors. In response to retinal damage, Müller cells undergo specific gene expression and functional changes that serve as a first line of defense for neurons, but can also lead to unwarranted cell dysfunction, contributing to cell death and neurodegeneration. In some species, Müller cells can reactivate their developmental program, promoting retinal regeneration and plasticity—a remarkable ability that holds promising therapeutic potential if harnessed in mammals.
The crucial and multifaceted roles of Müller cells—that we propose to collectively call “Müller cells trophism"—highlight the necessity of maintaining their functionality. Dysfunction of Müller cells, termed “Müller cells pathology,” has been associated with a plethora of retinal diseases, including age-related macular degeneration, diabetic retinopathy, vitreomacular disorders, macular telangiectasia, and inherited retinal dystrophies.
In this review, we outline how even subtle disruptions in Müller cells trophism can drive the pathological cascade of Müller cells pathology, emphasizing the need for targeted therapies to preserve retinal health and prevent disease progression.
ller细胞是一种重要的视网膜细胞类型,参与多种调节过程和功能,对视网膜健康和功能至关重要。作为视网膜神经元和光感受器的结构和功能支持,米勒细胞产生生长因子,调节离子和流体稳态,促进神经元信号传导。它们在视网膜的形态发生和细胞分化中起着关键作用,对黄斑的发育起着重要作用。由于其放射状形态和独特的细胞骨架组织,m ller细胞充当光纤,有效地将光子直接引导到光感受器。在视网膜损伤的反应中,m ller细胞经历特定的基因表达和功能变化,作为神经元的第一道防线,但也可能导致不必要的细胞功能障碍,导致细胞死亡和神经退行性变。在某些物种中,m ller细胞可以重新激活它们的发育程序,促进视网膜再生和可塑性——这是一种非凡的能力,如果在哺乳动物中加以利用,将有很大的治疗潜力。m ller细胞的关键和多方面的作用——我们建议将其统称为“m ller细胞营养”——强调了维持其功能的必要性。网膜细胞功能障碍,被称为“网膜细胞病理学”,与大量视网膜疾病有关,包括年龄相关性黄斑变性、糖尿病视网膜病变、玻璃体黄斑病变、黄斑毛细血管扩张和遗传性视网膜营养不良。在这篇综述中,我们概述了即使是m ller细胞营养的细微破坏也可以驱动m ller细胞病理级联反应,强调需要靶向治疗来保护视网膜健康和预防疾病进展。
