Have you ever seen fresh exudates forming on a chronic wound?

Watch as Julie Hamilton, M.D. demonstrates the the Vari-Chrome° Pro. She applies a pre-programmed setting that varies the wavelength between orange (600nm) and green (570nm). Watch as she wipes off the exudate that leaves a cooled (darker) stripe in the thermal imaging.

This is her first day using the device. It is also the first field testing of the Instant Feedback System™. The thermal imaging was a secondary test as no change was expected in the blood circulation around the wound during the visit. (Darker gray is colder.)

In the clip, Dr. Hamilton and Robert Hamilton, M.D. comment as they observe fresh exudates in the wound. Stop the video to observe wound features at different wavelengths. The top-right image shows the wound illuminated by the wavelengths in the scene video. (Please ignore the “pants on fire” on the observer in the background. The clips are presented as they were recorded.)

The clip is presented courtesy of Julie Hamilton, M.D. from HealingYourWound.com. The treatments were carried out at Prestige Regenerative Medicine, in Redding, CA.


Absorption of light may stimulate wavelength-specific wound factors to restart or accelerate healing.

Drs. Julie and Robert Hamilton were the first to test PhotoMed’s Instant Feedback System™ wound camera.
