Non-invasive in-vivo imaging of mechanoreceptors in skin using confocal microscopy
View Patent ↗Meissner's Corpuscles (MCs) are touch-pressure sensation receptors in glabrous skin. They are imaged by reflectance confocal microscopy to provide a non-invasive, in vivo quantification of their density or size to allow screening for, diagnosis or monitoring of sensory neuropathy and other peripheral nervous system disorders related to diabetes, HIV, or other conditions.
