Infrared images in the evaluation of the diabetic foot

Abstract

Introduction: Diabetes is a frequent pathology that has universal distribution. The incidence of the type 2 of this condition has been increasing with obesity. Early detection of dermatological, vascular, orthopedic and neurological origin pathologies helps the diagnosis and treatment of the diabetic foot. Objective: To evaluate the feet of pre-diabetic and diabetic patients bearers of onychomycosis using thermography, aiming at identifying the vascular, neurological and orthopedic impairment, as well as following up the clinical development. Methods: Capture of infrared images at baseline and after cold stimulus test, using an infrared sensor in a controlled environment. Results: This examination allowed the suspicion of peripheral neuropathy of fine fibers to be raised, as well as to verify areas of footwear pressure and to evaluate the progression of Charcot foot. Conclusions: Infrared imaging associated with dermatological examination can be a propaedeutic tool for the early identification of vasomotor alterations in the soles, even in asymptomatic patients.
