年龄相关性黄斑变性(ARMD)是导致老年人不可逆视力丧失的主要原因,其病理机制复杂,涉及氧化应激、炎症反应、代谢失衡等多种因素。近年来,体外细胞模型在ARMD研究中发挥了重要作用,通过模拟视网膜微环境来探讨疾病机制、筛选潜在药物,并评估治疗策略。文章系统综述了ARMD不同类型的体外细胞模型的研究进展,包括视网膜色素上皮细胞模型、3D细胞打印模型、类器官模型等,分析其构建方法、应用场景及各模型优缺点,并探讨当前研究中的争议与挑战。未来,随着微流控技术、基因编辑技术及3D打印技术的发展,这些模型有望朝着更加精准、个性化的方向发展,从而推动ARMD的早期诊断和个性化治疗的实现。

[Abstract]
Age-related macular degeneration(ARMD)is a leading cause of irreversible vision loss in the elderly, characterized by complex mechanisms such as oxidative stress, inflammation, and metabolic dysregulation. In vitro cellular models have become indispensable in ARMD research, enabling the study of ARMD pathogenesis, drug screening, and treatment evaluation through retinal microenvironment simulation. This review provides a systematic overview of recent advances in various in vitro models for ARMD research, encompassing retinal pigment epithelium(RPE)cell cultures, 3D bioprinted retinal constructs, and organoid technologies. We critically examine their development methodologies, experimental applications, as well as comparative strengths and weaknesses. The review also addresses ongoing debates and technical challenges in this research domain. In the future, continued progress in microfluidic platforms, gene-editing tools, and 3D bioprinting technologies promises to enhance the precision and patient-specific relevance of these models, ultimately facilitating earlier diagnosis and more tailored therapeutic interventions for ARMD.
