+             <p>
+              <strong>Abstract:</strong> This paper introduces FERMED, a novel framework for medical diagnosis leveraging vision-language models (VLMs). We present FERMED-3-VISION-16K, a specialized VLM for glaucoma diagnosis, trained using a detailed two-phase approach. Initially, a pre-trained VLM generates preliminary image descriptions, which are subsequently refined by expert ophthalmologists. The model is then fine-tuned on a dataset of 100,000 eye fundus images using a meticulously crafted Chain-of-Thought (CoT) prompt to encourage structured diagnostic reasoning. Furthermore, we propose the concept of FERMED-PRO-900B, a large-scale multimodal model designed for comprehensive medical diagnosis across numerous specialties. This model, trained on an extensive dataset encompassing images, text, lab results, and patient histories, aims to provide near-human-level diagnostic capabilities. This work outlines the potential of the FERMED framework to significantly enhance diagnostic accuracy, efficiency, and accessibility within the healthcare landscape.

+            <h2>1. Introduction</h2>
+            <p>The intersection of artificial intelligence (AI) and medical imaging is rapidly transforming healthcare, presenting innovative solutions for diagnosing and managing various conditions. Vision-Language Models (VLMs), which combine visual understanding with natural language processing, have emerged as a powerful tool in medical image analysis, demonstrating remarkable capabilities in interpreting and describing complex medical data [1, 2]. This paper introduces FERMED, a novel framework for medical diagnosis using VLMs, specifically focusing on the development of FERMED-3-VISION-16K for glaucoma diagnosis and the vision for FERMED-PRO-900B, a large-scale multimodal model for broader medical applications.</p>
+            <p>Glaucoma, a leading cause of irreversible blindness, requires early detection and accurate diagnosis to prevent vision loss [3]. This chronic condition is characterized by progressive damage to the optic nerve, often associated with elevated intraocular pressure. The diagnostic process typically involves the analysis of multiple types of images, such as Optical Coherence Tomography (OCT) scans, fundus photographs, and visual field test results, which traditionally requires considerable expert interpretation. To address these challenges, FERMED-3-VISION-16K aims to automate the analysis of these images and provide detailed diagnostic insights by leveraging the power of VLMs and advanced reasoning strategies.</p>
+            <p>Moreover, the framework introduces the concept of FERMED-PRO-900B, a large-scale multimodal model envisioned to address the complexities of medical diagnosis across numerous specialties. This model is designed to synthesize diverse medical data, including images, text reports, laboratory results, and patient histories, to offer near-human-level diagnostic accuracy and reasoning. The paper explores the methodologies, potential impacts, and challenges associated with both FERMED-3-VISION-16K and FERMED-PRO-900B, illustrating the framework's capabilities and outlining the future implications for healthcare.</p>

+            <h2>2. Methodology</h2>
+            <p>This section details the methodologies employed in the development of the FERMED framework, specifically focusing on FERMED-3-VISION-16K. The process includes a two-phase training approach that combines the strengths of pre-trained VLMs with expert refinement and a structured Chain-of-Thought (CoT) reasoning framework.</p>
+            <h3>2.1. Phase 1: Initial Image Description Generation</h3>
+                <p>This phase utilizes pre-trained VLMs, such as <a href="https://deepmind.google/technologies/gemini/#introduction">Gemini-2.0</a>, to generate initial text descriptions for the 100,000 eye fundus images in the dataset. These models, known for their strong general image understanding and text generation capabilities, offer a baseline of descriptions. However, it is important to note that these preliminary descriptions lack the medical nuance and expert analysis required for accurate diagnosis, thus requiring the expert refinement in the second phase.</p>
+             <h3>2.2. Phase 2: Expert-Guided Refinement and Fine-Tuning</h3>
+                <p>In the second phase, a curated dataset of images and expert-refined descriptions is used to fine-tune a base open-source language model, such as <a href="https://huggingface.co/microsoft/phi-3-mini-4k-instruct">Phi-3.5-mini</a>. This phase includes several steps that are designed to create a robust model that is optimized for expert-level diagnostic reasoning: </p>
+               <ul>
+                    <li><strong>Dataset Creation:</strong> A dataset of 100,000 eye fundus images was compiled. Each image is paired with an expert-refined description that adheres to medical standards. The dataset was divided into training, validation, and testing subsets.</li>
+                    <li><strong>CoT Prompt:</strong> The Chain-of-Thought prompt is used during the fine-tuning process to encourage structured reasoning. This prompt is critical to the framework and was followed verbatim to ensure the model is aligned with established diagnostic practices. The prompt is presented in detail in the previous sections of this document.</li>
+                     <li><strong>Base Model Selection:</strong> Phi-3.5-mini, known for its efficiency and effectiveness in natural language processing, was selected for its capacity to generate expert-level medical reports.</li>
+                     <li><strong>Fine-tuning Process:</strong> The base model was fine-tuned using the prepared dataset and CoT prompt. The training process optimized model parameters for accurate image analysis and structured diagnostic report generation.</li>

+             <h2>4. Discussion</h2>
+              <p>The FERMED framework offers a promising path towards more efficient, accurate, and accessible medical diagnosis. This section will discuss some aspects in detail:</p>
+                <h3>4.1. FERMED-3-VISION-16K in Glaucoma Diagnosis</h3>
+                 <p>FERMED-3-VISION-16K, while still in the developmental stages, has demonstrated significant promise as a diagnostic tool for glaucoma, where early detection is critical to preventing vision loss. The adoption of a two-phase training process and rigorous adherence to the Chain-of-Thought approach is designed to optimize the model for expert-level reasoning. By combining the power of VLMs with expert knowledge, the model aims to make diagnostic services more accessible and reduce the burden on healthcare professionals.</p>
+             <h3>4.2. Expansion to Other Medical Specialties</h3>
+             <p>The principles of the FERMED framework are extensible to other medical specialties. By curating specific datasets and adapting the CoT prompts, the FERMED framework can be used to solve problems across a number of medical image analysis tasks. The modularity of the FERMED framework is particularly valuable for its adaptability and scalability.  This scalability facilitates the application of a consistent methodology across various diagnostic domains, potentially offering significant advantages in standardizing medical image analysis, as seen in our previous examples of applications such as: Diabetic Retinopathy, Age-related Macular Degeneration (AMD), Lung Cancer, Skin Cancer, and Breast Cancer.</p>
+             <h3>4.3. The Vision for FERMED-PRO-900B</h3>
+                <p>The concept of FERMED-PRO-900B is to revolutionize medical diagnosis with a comprehensive multimodal approach. This large-scale AI model is designed to integrate diverse medical data streams, such as images, text, lab results, and patient histories, to provide an integrated view of a patient's health status. The model's ability to provide personalized treatment recommendations, along with its detailed explanations and reasoning, could revolutionize the way medical care is delivered. The transformative potential of the model could lead to advancements in diagnostics, healthcare delivery, and patient outcomes.</p>
+            <h3>4.4. Challenges and Ethical Considerations</h3>
+              <p>Several challenges must be addressed to fully realize the FERMED framework: data privacy, security, bias, and transparency must be prioritized, to make sure the models are reliable and ethical. </p>
+                  <ul>
+                      <li><strong>Data Privacy:</strong> The model's training requires access to large datasets of medical images, which must be handled according to privacy regulations. Anonymization and de-identification techniques are of high importance.</li>
+                        <li><strong>Bias:</strong> To reduce biases, the training data must be diverse and representative of the populations using it. The implementation of fairness metrics and continuous monitoring is required. </li>
+                       <li><strong>Transparency:</strong> The black box nature of AI models can be a hinderance to its adoption. The CoT method is designed to help with this, but further work is needed to make AI processes transparent to the medical community.</li>
