The assessment of skin conditions by digital images as part of the evaluation of treatment efficacy is not widely
used in podiatry. The main objective of our study was to evaluate quantitative measuring of tinea pedis (athlete's foot)
related medical endpoints via digital images of the affected feet areas before and after treatment as a supporting tool for
podiatrists. In order to do so, we analyzed photographs taken of patients who had participated in a previous clinical study.
During this already published study, the patient's fungal feet infections were treated only by wearing of antifungal socks
containing copper oxide. The efficacy of the treatment was then determined solely by clinical observations of the
podiatrist. In the current study, we randomly and blindly analyzed 282 digital images of patient's feet taken before and
after using the socks in the pilot study. The affected feet areas, in which the tinea pedis infection was manifested by
fissuring, scaling, erythema and/or vesicular eruptions, were determined before and after treatment by using ImageTool
software. Statistical analysis of these determinations demonstrated a significant reduction in the severity of all 4 endpoints
analyzed (p<0.05). This is in accordance with the results described in the published study, further establishing that using
socks containing copper oxide is efficacious in treating tinea pedis. The present study thus demonstrates that statistical
analysis of quantitative data obtained from digital images taken during treatment of tinea pedis is feasible and may serve
as a tool for podiatrists in monitoring treatment.
