Researchers have developed an ordinal latent diffusion model designed to generate color fundus images, specifically addressing the continuous nature of disease progression in ophthalmology. Unlike standard conditional diffusion models that treat disease stages as independent classes, this new model incorporates the ordered structure of diabetic retinopathy (DR) severity. By using a scalar disease representation, the model facilitates smooth transitions between adjacent stages, improving visual realism and clinical consistency. Evaluations on the EyePACS dataset showed a reduction in Fréchet inception distance for most DR stages and an increase in quadratic weighted kappa from 0.79 to 0.87, demonstrating its ability to capture a continuous spectrum of disease progression.
