全身疾病通过一定途径累及眼球,产生眼部病变,这些眼部病变的严重程度与全身疾病的进展密切相关。人工智能(artificial intelligence,AI)通过识别眼部病变,可以实现对全身疾病的评估,从而实现全身疾病早期诊断。检测巩膜黄染程度可评估黄疸;检测眼球后动脉血流动力学可评估肝硬化;检测视盘水肿,黄斑变性可评估慢性肾病(chronic kidney disease,CKD)进展;检测眼底血管损伤可评估糖尿病、高血压、动脉粥样硬化。临床医生可以通过眼部影像评估全身疾病的风险,其准确度依赖于临床医生的经验水平,而AI识别眼部病变评估全身疾病的准确度可与临床医生相媲美,在联合多种检测指标后,AI模型的特异性与敏感度均可得到显著提升,因此,充分利用AI可实现全身疾病的早诊早治。
Systemic diseases affect eyeballs through certain ways, resulting in eye diseases; The severity of eye diseases is closely related to the progress of systemic diseases. By identifying eye diseases, artificial intelligence (AI) can assess systemic diseases, so as to make early diagnosis of systemic diseases. For example, detection of the degree of icteric sclera can be used to assess jaundice. Detection of the hemodynamics of posterior eyeball can be used to evaluate cirrhosis. Detection of optic disc edema and macular degeneration can be used to evaluate the progress of chronic kidney disease (CKD). Detection of ocular fundus vascular injury can be used to assess diabetes, hypertension and atherosclerosis. Clinicians can estimate the risk of systemic diseases through eye images, and its accuracy depends on the experience level of clinicians, while the accuracy of AI in identifying eye diseases and evaluating systemic diseases can be comparable to clinicians. After combining various detection indexes, the specificity and sensitivity of AI model can be significantly improved, so early diagnosis and early treatment of systemic diseases can be realized by making full use of AI.
碳点是一种新型荧光碳纳米材料,直径一般小于10 nm,具有自发荧光、高生物组织相容性、易于修饰、成本低廉等优点,在生物医学领域拥有广阔的应用前景。眼球因其独特的屏障结构,常规药物停留时间短、穿透性差,通过局部滴眼到达病灶的药物浓度有限,需要增加给药频次以保持药效。另外,糖尿病性黄斑水肿(diabetic macular edema,DME)、脉络膜新生血管(diabetic macular edema,CNV)等疾病的治疗给药则需依赖于玻璃体腔注射,该方法属于有创操作,有引起潜在并发症的可能,且需多次注射,给患者造成了沉重的心理和经济负担。优化眼部给药方法一直是眼科学领域的研究热点。基于碳点的优异特性,碳点在眼部药物递送、眼部成像、眼疾病诊疗中已展现出优秀的应用潜力。本综述将综合介绍碳点的特点及近十年来碳点在眼科疾病诊疗中的研究进展,旨在提供关于碳点在眼科应用现状的系统性认识,为未来研究提供方向。
Carbon dots is a new type of fluorescent carbon nanomaterial, which the diameter is generally less than 10 nm, has the advantages of self-fluorescence, remarkable biocompatibility, easy modification, low cost and so on, has a broad application prospect in the biomedical field. Due to the unique barrier of the eye, conventional drugs have a short residence time and poor penetration, so the concentration of drugs that can reach the lesions through local eye drops is limited, and for what to increase the frequency of administration to maintain efficacy. Up to now, the treatment of posterior eye diseases, such as diabetic macular edema (DME), choroidal neovascularization (CNV) and other diseases still rely on repeated vitreous injection, which is an invasive procedure with potential complications, and need multiple injections, causing a heavy psychological and economic burden on patients. Optimizing the method of ocular drug delivery has always been a hot topic in the field of ophthalmology. Carbon dots have shown excellent application potential in the ocular drug delivery, ocular imaging, and diagnosis and treatment of ocular disease based on its excellent characteristics. This review will systematically introduce the characteristics of carbon dots and the application of carbon dots in the diagnosis and treatment of eye diseases, aiming to provide a comprehensive understanding of the current situation of the application of carbon dots in ophthalmology and provide directions for future research.

It is estimated that there are nearly 1.4 billion myopic people in the world, and myopia becomes a significant global health problem. Myopia not only affects visual health, but also leads to serious complications such as macular degeneration and retinal detachment, which can cause blindness in severe cases. Apart from its impact on health, myopia also imposes a substantial economic burden. This burden includes direct medical costs (e.g., expenses for eyeglasses, contact lenses, and corrective surgeries) as well as indirect costs (e.g., reduced productivity, learning abilities, and quality of life). The prevalence of myopia is particularly high in China, posing a threat not only to individual health, but also to society and the economy. International studies on the economic burden of myopia have examined the direct medical costs, patient time costs and productivity loss. These studies help governments and health authorities understand the economic impact of myopia to develop effective public health and resource allocation strategies.. By optimizing medical resources and reducing social costs, these measures aim to alleviate the economic burden. This article provides an overview of the economic burden of myopia, including its definition, measurement, current status at home and abroad, and the importance of prevention and alleviation. It also highlights the current research directions and findings, to provide focusing fields and foundations for future research.
糖尿病视网膜病变是最为常见的糖尿病微血管并发症,主要由糖尿病引起的机体代谢紊乱导致。而然在临床工作中发现,部分患者通过单纯控制血糖以延缓糖尿病视网膜病变进展,所取得效果不甚理想,一些其他因素对于糖尿病视网膜病变的发生、发展,也起到不可忽视的作用。研究表明,在并发高脂血症的糖尿病视网膜病变患者中,胆固醇代谢异常是诱发视网膜病变的主要原因之一。胆固醇代谢异常通过减弱肝脏X受体,导致胆固醇在视网膜上不断积累,降低视网膜血管内皮功能,从而造成视网膜缺血、缺氧环境的形成,又可通过增加炎症因子和细胞黏附分子-1的表达,使原本病态的糖尿病视网膜血管变得更加脆弱,该文总结了糖尿病视网膜病变的病理因素,对比分析当前糖尿病视网膜病变的主要治疗手段,通过分析胆固醇逆向转运(cholesterol reverse transport,RCT)途径转运对糖尿病视网膜病变发生、发展的影响,发现降低高血脂可提高糖尿病视网膜病变的治愈率,这将为糖尿病视网膜病变的临床防治工作提供新思路。
Diabetic retinopathy is the most common diabetic microvascular complication, which is mainly caused by metabolic disorders caused by diabetes. However, in clinical work, it is found that some patients do not achieve satisfactory results in delaying the progress of diabetic retinopathy by simply controlling blood sugar, and some other factors contribute to the occurrence and development of diabetic retinopathy. Also played a role that can not be ignored. Studies have shown that abnormal cholesterol metabolism is one of the main causes of retinopathy in diabetic retinopathy patients with hyperlipidemia. Abnormal cholesterol metabolism leads to the accumulation of cholesterol in the retina and the decrease of retinal vascular endothelial function by weakening the X receptor in the liver, resulting in the formation of retinal ischemia and hypoxia environment. it can also increase the expression of inflammatory cytokines and cell adhesion molecule-1 to make the originally morbid retinal vessels more fragile. This paper summarizes the pathological factors of diabetic retinopathy. By comparing and analyzing the main treatment methods of diabetic retinopathy at present, and by analyzing the influence of cholesterol reverse transport (cholesterolreversetransport,RCT) pathway on the occurrence and development of diabetic retinopathy, it is found that reducing hyperlipidemia can improve the cure rate of diabetic retinopathy, which will provide new ideas for the clinical prevention and treatment of diabetic retinopathy.
