*The use of low energy photon therapy (LEPT) in venous leg ulcers: a
double-blind, placebo-controlled study.*

BACKGROUND: Venous ulcers are estimated to be present in 0.2 to 0.4% of
the population. Although new therapies have significant promise,
nonhealing ulcers still represent a significant problem. OBJECTIVE: To
evaluate the efficacy of low energy photon therapy (LEPT) in the
treatment of venous leg ulcers. METHODS: A placebo-controlled,
double-blind study using low energy photon therapy was performed in nine
patients with 12 venous ulcers. Treatment was given three times a week
for 10 weeks, using two monochromatic optical sources. One source
provided a wavelength (lambda) of 660 nm (red) while the second source
delivered a wavelength of 880 nm (infrared). Two optical probes were
used, one consisted of an array of 22 monochromatic sources, operating
at a wavelength of 660 nm and covering an area 6 x 10 cm2. The second
probe had seven infrared sources, operating at a wavelength of 880 nm
and covering an area of 4 cm2. The above configuration of optical probes
was selected to cover the majority of the ulcer area being treated. The
patients who were randomized to placebo treatment received sham therapy
from an identical-appearing light source from the same delivery system.
RESULTS: Nine patients with 12 venous ulcers were randomized to receive
LEPT or placebo therapy. At the conclusion of the study, the percentage
of the initial ulcer area remaining unhealed in the LEPT and placebo
groups was 24.4% and 84.7%, respectively (P = 0.0008). The decrease in
ulcer area (compared to baseline) observed in the LEPT and placebo
groups was 193.0 mm2 and 14.7 mm2, respectively (P = 0.0002). One
patient dropped out of the study, complaining of lack of treatment
efficacy; he was found to be randomized to the placebo group. There were
no adverse effects. CONCLUSION: In this placebo-controlled, double-blind
study LEPT was an effective modality for the treatment of venous leg ulcers.

under control results in many additional health risks including skin
ulcers that are extremely hard to cure. Laser therapy has been seen to
be effective. This study shows that two wavelengths, 660 and 880 nm,
when used together seems to be more effective than other forms of light
therapy. This hypothesis will be tested with larger populations.

respond very well to the red 660 light. One man had a big ulcer on his leg that
the docs could not heal up for many months. Application of the light closed it
up mostly in a couple days.
