Abstract

Diabetic keratopathy (DK) is a common ocular complication of diabetes mellitus (DM), affecting almost half of all diabetic patients. It is characterized by delayed healing of epithelial wounds, reduced corneal sensitivity, and persistent epithelial defects, which, in turn, significantly impair vision and quality of life. The limited understanding of its pathogenesis and the lack of effective treatments highlight the urgent need for more physiologically relevant experimental models. The three-dimensional (3D) models currently available provide valuable information on the pathophysiology of DK, although none of them yet fully reproduce the diabetic corneal phenotype complex. After a brief overview of corneal anatomy, the present review aims to systematically analyze the current 3D in vitro models developed for the study of DK, in terms of tissue architecture, presence of diabetic stimuli, and ability to replicate pathological traits.
