With the rapid development of artificial intelligence (AI) technology, its application in the field of healthcare is bringing revolutionary changes. Cataracts, as one of the most common reversible visual impairments worldwide, still face many practical issues in terms of limited medical resources, low diagnostic accuracy, and low referral efficiency. Therefore, it is crucial to utilize AI technology's powerful computational analysis and intelligent decision-making capabilities to optimize traditional medical practices and safeguard people's visual health.This article investigates the applications of AI technology on a new model of hierarchic diagnosis and treatment for cataracts, including automatic analysis and recognition of cataract images, remote healthcare, and referral support. These applications can bring significant benefits and important impacts to cataract patients, society, and governments. They can help improve the efficiency of cataract diagnosis and treatment, alleviate the imbalance of medical resources, optimize the allocation and management of healthcare resources, and promote societal health progress.However, the practical application of AI technology also faces risks and challenges. It is important to fully prioritize and protect patients' data privacy and security by establishing strict regulatory and oversight mechanisms. Additionally, continuous efforts should be made to enhance technological innovation and comprehensively evaluate the robustness, fairness, and interpretability of AI algorithms to further improve the accuracy and trustworthiness of AI systems.
据统计，目前全球有近14亿近视人口，近视已成为全球主要的健康问题。近视不仅影响个人的视力健康，还可能引发多种严重的并发症，如高度近视相关的黄斑变性和视网膜脱离等，严重时可导致失明。除了对个人健康的影响，近视还带来了巨大的经济负担，包括直接医疗成本(如眼镜、隐形眼镜、矫正手术等费用)和间接成本(如生产力下降、学习能力降低和生活质量的下降)。在中国，近视的问题尤其显著，近视患病率居高不下，这不仅对个人健康构成威胁，也对社会和经济造成重大影响。国际上，近视的经济负担研究涵盖了医疗直接成本、患者时间成本及生产力损失等方面，可以帮助政府和卫生部门了解近视疾病的经济影响，从而制定合理的公共卫生政策和资源分配策略，优化医疗资源使用，减少社会成本。该文从近视疾病经济负担的构成及其测算方式、国内外经济负担现况等方面对近视疾病经济负担进行简要综述，旨在提供一个关于近视疾病经济负担的综合性认识，指出当前研究的方向和成果，以及预防近视和减轻其经济负担的重要性，为未来研究提供方向和基础。
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.
