Macular edema is the major cause of decreased vision in patients with diabetes. Antioxidative and anti-inflammatory effects of photobiomodulation (PBM) have been reported with near-infrared irradiation.
Objective:
In this study, the efficacy and safety of PBM with near-infrared radiation in a patient with diabetic macular edema were assessed.
Methods:
We present the case of a 60-year-old man with diabetic macular edema responding to 670 nm light PBM alone.
Results:
After PBM, his vision improved and macular edema resolved on optical coherence tomography (OCT) findings without adverse events. In 16 months follow-up, visual acuity remained stable and OCT showed no evidence of recurrence of edema.
Conclusions:
Six hundred seventy nanometers light PBM can be potentially considered as a therapeutic method in diabetic patients with macular edema. Also, it provides a noninvasive and nonexpensive treatment in home.
