01 Opening Remarks

02 Disease Burden and Clinical Challenges

2.1 Disease Burden：A Public Health Challenge That Cannot Be Ignored

China's diabetics are over 140 million people.，其中糖网患病率约23%；青光眼患者超21 Million。Behind these figures lie the health challenges faced by tens of millions of patients and their families。 随着人口老龄化加速、生活方式改变以及环境因素影响，眼底相关疾病的发病率仍呈持续上升趋势。 更值得关注的是，许多眼底疾病在早期缺乏特异性症状，患者就诊时往往已处于疾病中晚期，治疗效果和预后大打折扣。

以眼底照相as the core的Imaging学检查，是眼底疾病诊断和治疗决策的基石。 然而，Insufficient Diagnostic Consistency——这一data深刻反映了当前眼底眼底照相 + 光学相干断层扫描（OCT）诊断面临的核心挑战。 A considerable proportion of patients fail to receive an accurate diagnosis within the optimal treatment window, which not only delays treatment but also increases the medical burden and the suffering of patients。 如何提高眼底疾病的早期诊断率和Accuracy，是当前Clinical医学面临的重要课题。

2.2 Three Major Pain Points in Clinical Diagnosis

2.3 The Capability Gap in Primary Care

The shortage of ophthalmologists in China exceeds 100,000。This data reveals a stark reality：优质的眼底照相 + 光学相干断层扫描（OCT）诊断资源高度集中在大城市三甲医院， Primary-care medical institutions have obvious shortcomings in equipment, talent reserves and diagnostic capability。对于广大基层患者而言，获得高quality的眼底Diagnosis of imagesServices并非易事。

这种医疗资源分布的不均衡，不仅加剧了"看病难、看病贵"的社会问题，也制约了眼底疾病早筛早诊的推广。 如何借助人工智能技术，打破地域限制，让优质的眼底照相 + 光学相干断层扫描（OCT）诊断能力下沉到基层， is one of the core issues that Changsha Langhui Information Technology Co., Ltd. has long focused on and is committed to solving。

以深度学习为代表的人工智能技术，正在从根本上改变眼底眼底照相 + 光学相干断层扫描（OCT）的诊断范式。 AI has the following irreplaceable advantages over traditional artificial diagnosis:

3.3 Triple value of AI breakdown

人工智能技术在眼底眼底照相 + 光学相干断层扫描（OCT）Domains的应用，不仅仅是效率的提升，更是诊断模式的根本变革。 Its core values are reflected at three levels:

04 2025-2026 Frontier Technology Breakthroughs

2025 Years至2026年，是眼底照相 + 光学相干断层扫描（OCT）AI技术加速迭代的关键时期。Foundation models, self-supervised learning, Multimodal Fusion（Multimodal Fusion）等Frontier技术的快速发展，正在将眼底ImagingAI推向一个全新的高度。 The following are the five technology breakthrough directions most worthy of attention in this field。

4.1 Base model: from "special AI" to "general AI" Viet.

长期以来，眼底眼底照相 + 光学相干断层扫描（OCT）AIModels大多是针对单一Tasks进行Training的"专用Models"。 However, with the rise of foundation model technology, this landscape is undergoing a fundamental change。 A general-purpose vision foundation model pre-trained on large-scale medical imaging data can be adapted to a wide range of downstream tasks with only minimal fine-tuning, greatly reducing the cost and cycle of model development。

In 2025, several top international teams successively released foundation models designed specifically for medical imaging。These models are pre-trained on hundreds of millions or even billions of medical images, learning rich feature representations of medical images。在眼底眼底照相 + 光学相干断层扫描（OCT）Tasks上，这些基础Models展现出了惊人的性能， setting new state-of-the-art records on multiple benchmarks。More importantly, they demonstrate powerful generalization capability and few-shot learning ability, providing a new approach to solving the "data scarcity" pain point in the field of medical AI。

Changsha Langhui Information Technology Co., Ltd. is also actively positioning itself in this direction。基于80,000+例眼科Imagingdata（眼底彩照+OCT+OCTA）眼底Imagingdata， LanghuiResearch院正在Training专门针对眼底眼底照相 + 光学相干断层扫描（OCT）的Domains基础Models。 初步结果显示，该Models在多种眼底疾病诊断Tasks上均取得了优异表现， Compared with traditional single-task models, performance improves significantly and generalization capability is stronger。

4.2 Self-Supervised Learning：Unleashing the Huge Value of Unlabeled Data

In medical imaging, annotated data is costly and time-consuming to acquire, while unlabeled data is relatively abundant。 How to effectively leverage massive amounts of unlabeled data has always been one of the core topics in medical AI research。 The maturity of self-supervised learning technology provides an effective solution to this problem。

2025 Years以来，自监督学习在眼底眼底照相 + 光学相干断层扫描（OCT）Domains取得了一系列重要进展。 By designing ingenious pre-training tasks (such as image inpainting, contrastive learning and masked image modeling), 让Models从Massive的未Annotation眼底照相 + 光学相干断层扫描（OCT）Image中学习有用的特征表示。 Experiments show that models pretrained with self-supervised learning can match or even exceed fully supervised training results on downstream diagnostic tasks using only a small amount of annotated data。

This technological breakthrough has important practical significance。It means that for some rare and uncommon diseases, Even with limited annotated data, self-supervised pre-training can be used to build AI models with strong performance。 At the same time, self-supervised learning offers a new paradigm for multi-center data collaboration — individual centers do not need to share raw data or annotations, Simply sharing the knowledge from model pre-training enables collective progress。

4.3 Multimodal Fusion：Comprehensive Diagnosis Integrating Imaging, Clinical and Genomic Data

Clinical diagnosis has never been a single-modality decision。In real clinical practice, doctors need to comprehensively consider the patient's imaging findings, Clinical symptoms, laboratory tests, family history and even genetic test results must all be considered to arrive at the most accurate diagnosis。 Multimodal fusion technology is precisely what enables AI to acquire such comprehensive analytical capability。

2025-2026年，Multimodal Fusion在眼底疾病诊断中取得了显著进展。 Researchers have developed a variety of effective multimodal fusion strategies, including early fusion, late fusion and hybrid fusion architectures, as well as attention-mechanism-based cross-modal feature interaction methods。 这些技术使得AIModels能够同时Processing眼底照相 + 光学相干断层扫描（OCT）Imaging、ClinicalText、实验室data等多种信息， outputting more comprehensive and more precise diagnostic results。

以眼底肿瘤诊断为例，MultimodularAIModels不仅能够分析眼底照相 + 光学相干断层扫描（OCT）Image中的肿瘤形态学特征， It can also incorporate the patient's tumor marker levels, clinical manifestations, genetic test results and other information, making more accurate predictions of tumor benignity and malignancy, invasiveness and prognosis, providing clinicians with more valuable decision support。

4.4 Empowerment by Large Language Models：End-to-End Intelligence from Image to Report

大LanguageModels（Large Language Model, LLM）的兴起，为眼底照相 + 光学相干断层扫描（OCT）AI带来了新的想象空间。 By combining vision models with language models to build vision-language multimodal large models, 能够实现从眼底照相 + 光学相干断层扫描（OCT）Image直接生成Structured、Reg范化的诊断reports， This will greatly improve the work efficiency of radiology departments。

In 2025, several research teams have already achieved important breakthroughs in this direction。 他们构建的视觉-Language模型不仅能够准确识别眼底的各种病变， It can also generate imaging reports that comply with clinical standards and have a clear structure。 Even more exciting is that these models also possess a certain "conversational" capability, Doctors can interact with the model in natural language, asking various questions about the image, This brings a brand-new human-machine collaboration experience to clinical work。

4.5 Explainable AI: Transparent and credible AI decision-making

In the medical field, the explainability of AI models is of critical importance。A "black box" AI system, No matter how high the performance, it is difficult to gain the trust of clinicians and the approval of regulators。 2025-2026年，可解释AI（Explainable AI, XAI）在眼底照相 + 光学相干断层扫描（OCT）Domains取得了重要进展。

Research人员开发出了多种针对眼底眼底照相 + 光学相干断层扫描（OCT）AI的可解释性方Law， Including attention-based visualization methods, feature attribution-based explanation methods, concept activation vectors and more。 These methods allow doctors to clearly see which regions and which features of the image the AI model based its diagnostic decision on, greatly enhancing the transparency and trustworthiness of AI systems。

Changsha Langhui Information Technology Co., Ltd. has also conducted in-depth exploration in explainable AI。 Langhui的眼底AI系统不仅提供Diagnostic Conclusion， It also presents the basis of the model's decisions to doctors through heatmaps, feature annotations and other means, allowing doctors to "know not only what the AI concludes, but also why" when using AI assistance。
