Optical coherence tomography: a novel imaging approach to visualize and quantify cutaneous microvascular structure and function in patients with diabetes.

The relative changes in OCT-derived diameter from baseline in response to local heating were significantly different between groups (p<0.001, one-way ANOVA) where the responses were much lower in the DFU group (18.8%±13.6%, p<0.001) and the DNU group (35.8%±17.2%, p=0.044) compared with CON group (53.1%±25.1%), and the difference between the DFU and DNU groups was borderline significant (p=0.050).
