Abnormalities in the retina have a profound impact on vision, and accurate diagnosis and monitoring are essential for effective clinical management. Retinal hyperreflective foci (HRF), lesions, or dots, identified using optical coherence tomography (OCT), are observed in both animals and humans and have been associated with several ocular conditions, including diabetic retinopathy (DR), age-related macular degeneration (AMD), and retinal vascular diseases. To evaluate the relevance of retinal HRF, we conducted a comprehensive scoping review of the literature published up to July 2024 including in the discussion key papers that emerged in 2025. Our search spanned electronic databases utilizing carefully identified search terms related to HRF and OCT within the last six years. We excluded publications on HRF outside the retina, treatments, non-peer-reviewed content, duplicates, studies older than 6 years, and those not focused on AMD, DR, or glaucoma. A total of 141,085 records were initially identified from various databases and further refined based on keywords and content relevance. Finally, 42 reports meeting the criteria were retained for in-depth analysis. HRF were observed mainly in OCT scans of the AMD retina, as well as in DR and, to a lesser extent, in other retinopathies and interestingly in glaucoma. In AMD, HRF are described as a marker for disease progression, often associated with a compromised photoreceptor structure. In DR, HRF indicated issues such as abnormal blood vessels and cellular changes linked to microglia activation. In glaucoma, HRF may reflect microglia and macrophage activation. Most publications concur that the presence of HRF correlates with inflammatory processes and aging in the retina, with early appearance of small HRF serving as a biomarker for ocular disease. The size of HRF and their location were consistent with disease presentation. There is an agreement that HRF of less than 30 μm are biomarkers of inflammation in the retina despite having variable intraretinal locations. HRF resulting from the effect of aging can be discerned from AMD based on their quantity and appearance. The results show the importance of HRF as a biomarker of ocular disease and confirm that HRF are indicative of an inflammatory eye disorder.
视网膜异常对视力有深远影响,准确的诊断和监测对于有效的临床管理至关重要。使用光学相干断层扫描(OCT)识别出的视网膜高反射灶(HRF)、病变或小点,在动物和人类中均有观察到,并与多种眼部疾病相关,包括糖尿病视网膜病变(DR)、年龄相关性黄斑变性(AMD)和视网膜血管疾病。为了评估视网膜HRF的相关性,我们对截至2024年7月发表的文献进行了全面的范围综述,包括在讨论中纳入2025年出现的关键论文。我们的搜索涵盖了电子数据库,使用了在过去六年中精心确定的与HRF和OCT相关的搜索词。我们排除了视网膜外HRF的出版物、治疗方法、非同行评审的内容、重复项、超过6年的研究以及那些未聚焦于AMD、DR或青光眼的研究。最初从各种数据库中识别出总共141,085条记录,并根据关键词和内容相关性进一步筛选。最后,保留了42份符合标准的报告进行深入分析。HRF主要在AMD视网膜的OCT扫描中观察到,也在DR中观察到,在较小程度上还在其他视网膜病变以及有趣的是在青光眼中观察到。在AMD中,HRF被描述为疾病进展的标志物,通常与光感受器结构受损有关。在DR中,HRF表明存在诸如异常血管和与小胶质细胞激活相关的细胞变化等问题。在青光眼中,HRF可能反映小胶质细胞和巨噬细胞的激活。大多数出版物一致认为,HRF的存在与视网膜中的炎症过程和衰老相关,小HRF的早期出现可作为眼部疾病的生物标志物。HRF的大小及其位置与疾病表现一致。尽管HRF在视网膜内的位置各不相同,但人们一致认为小于30μm的HRF是视网膜炎症的生物标志物。基于其数量和外观,可以将衰老影响导致的HRF与AMD区分开来。结果表明HRF作为眼部疾病生物标志物的重要性,并证实HRF指示炎症性眼病。
