Despite diverse clinical manifestations, these conditions share systemic endothelial dysfunction (ED) as a common pathophysiological hallmark. The retina, accessible through non-invasive imaging, provides a unique window into systemic microvascular health. Over the past decades, retinal vessel analysis (RVA), both static and dynamic, has emerged as a robust tool for detecting and predicting microvascular alterations in inflammatory diseases. Large population-based cohorts, including the Atherosclerosis Risk in Communities (ARIC, n > 9000 participants) study and the Rotterdam Study (n > 5000), have shown that retinal diameter changes independently predict incident CV events and all-cause mortality. Recent UK Biobank (n > 45,000) analyses further demonstrate incremental value in stroke prediction beyond traditional risk factors (AUC 0.739 to 0.752; p < 0.001). Other retinal imaging modalities, such as optical coherence tomography angiography (OCTA) and adaptive optics (AO), provide complementary high-resolution structural data on capillary architecture and perfusion integrity. The retinal vascular phenotype reflects both shared and disease-specific mechanisms of ED. Therefore, accurate interpretation of retinal biomarkers requires an understanding of the molecular pathways that shape ED across disease entities, thereby forming the conceptual foundation of oculomics. We synthesize current evidence linking systemic ED to retinal microvascular structure and function across major categories of inflammatory disease. We integrate findings from static and dynamic RVA, OCTA, and AO, discuss their mechanistic interpretation within the emerging framework of oculomics, and critically evaluate challenges for clinical translation. Finally, we outline how artificial intelligence (AI) may facilitate robust, scalable implementation of retinal biomarkers for risk stratification, disease monitoring, and outcome prediction.

This review aims to redefine AMD progression through a Müller glial cell-centered framework that integrates cellular homeostasis, structural transitions, and stage-dependent therapeutic implications. Emerging transcriptomic, histologic, and functional evidence demonstrates that Müller glial cells actively participate in AMD pathobiology, including complement regulation, metabolic coupling, redox control, and inflammatory signaling. In early AMD, Müller glial cells exhibit adaptive responses that preserve retinal integrity despite increasing metabolic and extracellular stress. Progressive accumulation of basal laminar deposits and extracellular remodeling imposes diffusion constraints and inflammatory burden, promoting glial reprogramming. A critical transition occurs at external limiting membrane (ELM) descent, which corresponds to loss of photoreceptor support, disruption of retinal compartmentalization, and onset of irreversible degeneration. Beyond this threshold, Müller glial cells undergo structural remodeling and contribute to formation of subretinal glial membranes, reflecting a shift from homeostatic support to containment. This framework proposes a biologically testable staging axis from preserved Müller glial cell function to progressive dysfunction, aligning disease progression with therapeutic windows. Pre-ELM stages are characterized by retained plasticity and suitability for neuroprotective and metabolic interventions, whereas post-ELM stages require strategies focused on stabilization and limiting degeneration. Importantly, current clinical trials do not incorporate Müller glial cell state or ELM integrity as stratification variables, contributing to outcome insensitivity. In conclusion, Müller glial cells function as central regulators of retinal homeostasis and disease progression in AMD. Integrating glial biology with structural biomarkers may enable stage-specific precision therapies and improve clinical trial design.","PeriodicalId":21159,"journal":{"name":"Progress in Retinal and Eye Research","volume":"26 1","pages":""},"PeriodicalIF":17.8,"publicationDate":"2026-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147681455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ORT arises from sustained photoreceptor and retinal pigment epithelium (RPE) injury, leading to the reorganization of surviving cones ensheathed by gliotic Müller cell processes. This review integrates historical, histological, and imaging data to elucidate ORT's cellular composition, formation mechanisms, and disease-specific patterns. We introduce a novel etiological classification of ORT, categorized as degenerative, fibrotic, or edematous ORT according to predominant pathogenic drivers, to facilitate cross-disease comparison and prognostic stratification. Clinically, ORT serves as a non-exudative biomarker of chronic retinal injury, aiding differential diagnosis and informing treatment strategies. In age-related macular degeneration, ORT is associated with subretinal fibrosis and poor visual outcomes; in geographic atrophy, it may signal slower lesion progression. In inherited retinal dystrophies, ORT reflects genotype-specific vulnerabilities and residual photoreceptor survival, with implications for therapeutic targeting.
