Abstract
Recent advancements in deep learning have shown significant potential for
classifying retinal diseases using color fundus images. However, existing works
predominantly rely exclusively on image data, lack interpretability in their
diagnostic decisions, and treat medical professionals primarily as annotators
for ground truth labeling. To fill this gap, we implement two key strategies:
extracting interpretable concepts of retinal diseases using the knowledge base
of GPT models and incorporating these concepts as a language component in
prompt-learning to train vision-language (VL) models with both fundus images
and their associated concepts. Our method not only improves retinal disease
classification but also enriches few-shot and zero-shot detection (novel
disease detection), while offering the added benefit of concept-based model
interpretability. Our extensive evaluation across two diverse retinal fundus
image datasets illustrates substantial performance gains in VL-model based
few-shot methodologies through our concept integration approach, demonstrating
an average improvement of approximately 5.8\% and 2.7\% mean average precision
for 16-shot learning and zero-shot (novel class) detection respectively. Our
method marks a pivotal step towards interpretable and efficient retinal disease
recognition for real-world clinical applications.
