RESUMEN
BACKGROUND AND OBJECTIVE: Previous studies in a hairless Guinea pig model showed that transdermal application of glycerol effected a temporary reduction in dermal scatter of light. This study focuses on the application of this protocol on human patients. STUDY DESIGN/MATERIALS AND METHODS: After stratum corneal removal, glycerol was applied to human subjects using a low pressure transdermal application device. Optical coherence tomography imaging showed increased intensity of radiation reaching deeper regions in the skin and photographs showed enhanced visualization of dermal structures. RESULTS/CONCLUSION: Topically applied glycerol increased light penetration of in vivo corneal-stripped skin. This minimally invasive approach to temporary dermal scatter reduction has the potential to improve the efficacy of light-based diagnostic or therapeutic devices.
