1. Introduction

The rapid advancements in artificial intelligence (AI), particularly in deep learning and natural language processing, have opened new avenues for revolutionizing healthcare. Vision-language models (VLMs), capable of understanding and generating text descriptions of visual content, have shown remarkable potential in various applications, including medical image analysis. This paper presents the development plan for FERMED-3-VISION-16K, a specialized VLM designed for automated glaucoma diagnosis from medical images such as Optical Coherence Tomography (OCT) scans, fundus photographs, and visual field test results. Furthermore, we introduce the concept of FERMED-PRO-900B, a visionary large-scale multimodal model envisioned to provide comprehensive diagnostic capabilities across a wide range of medical specialties.

Glaucoma, a leading cause of irreversible blindness worldwide, is characterized by progressive optic nerve damage [1]. Early detection and management are critical for preserving vision. The current diagnostic process relies on a comprehensive evaluation involving multiple imaging modalities and expert interpretation, which can be time-consuming and resource-intensive. FERMED-3-VISION-16K aims to address this challenge by automating the analysis of these images and providing detailed diagnostic reasoning, thereby improving diagnostic accuracy and efficiency.

Building upon the principles of specialized VLMs, FERMED-PRO-900B is conceptualized as a transformative AI system capable of analyzing a vast array of medical data, including images, text reports, laboratory results, and patient histories. With an envisioned 900 billion parameters, this model would be trained on a massive dataset encompassing diverse medical specialties, enabling it to achieve near-human-level diagnostic accuracy and reasoning capabilities. Such a system could revolutionize healthcare by providing rapid, accurate, and accessible diagnostic support to medical professionals worldwide.

This phase leverages pre-trained VLMs like Gemini-2.0 or similar models. While not specifically trained for medical images, these models possess strong image understanding and text generation abilities.

Image-to-Text Generation: The pre-trained VLM will generate initial descriptions for 100,000 eye fundus images.
Expert Refinement: A team of expert ophthalmologists will review, refine, and correct these descriptions, ensuring medical accuracy and adherence to established diagnostic criteria.

2.1.2. Phase 2: Fine-tuning with Specialized Dataset and CoT Prompting

This phase involves fine-tuning a base open-source language model, such as Phi-3.5-mini, on the curated dataset of images and refined descriptions.

Dataset Creation: 100,000 eye fundus images paired with expert-refined descriptions, split into training, validation, and testing sets.
Base Model Selection: Phi-3.5-mini, known for its strong performance and compact size.
Prompt Engineering: A detailed Chain-of-Thought (CoT) prompt will guide the model through a structured diagnostic process, as outlined in the previous response. This prompt is designed to elicit step-by-step reasoning, connecting findings across different modalities (OCT, fundus, visual field) and offering a possible diagnosis with a differential diagnosis.
Fine-tuning Process: The base model will be fine-tuned using the dataset and CoT prompt to optimize its parameters for accurate image analysis and diagnostic report generation.
Evaluation Metrics: Model performance will be evaluated using metrics such as diagnostic accuracy, completeness of analysis, coherence of reasoning, adherence to output format, BLEU, ROUGE, METEOR, and clinical utility as assessed by ophthalmologists.
