Treating Diabetic Retinopathy with Light Therapy

LED Light Therapy (photomedicine) is a non-invasive, inexpensive, and easily administered treatment.  Early studies show that light therapy inhibits further damage caused by diabetic retinopathy, and has no known side effects making it a much simpler and safer treatment alternative to laser treatment.


One 90 second dose directly over each closed eye twice per day.

Results of a Clinical Study on Light Therapy for Diabetic Retinopathy

The purpose of the study was to investigate the therapeutic efficacy of 670-nm photobiomodulation (PBM) in rodent and cultured cell models of diabetic retinopathy.

Beneficial effects of PBM were observed on the neural and vascular elements of retina. Daily 670-nm PBM treatment (6 J/cm(2)) and resulted in significant inhibition in the diabetes-induced death of retinal ganglion cells, as well as a 50% improvement of the ERG amplitude (photopic b wave responses) (both P < 0.01).

PBM ameliorated lesions of diabetic retinopathy in vivo and reduced oxidative stress and cell death in vitro. PBM is noninvasive, inexpensive, and easy to administer and carries minimal risk.  PBM is a simple adjunct therapy to help reduce the development of diabetic retinopathy
