Photobiomodulation for the Treatment of Diabetic Macular Edema

Battery operated, hand-held, 10 cm2 Light Emitting Diode (LED) array designed to deliver 50 mW/cm2 of light for 90 seconds resulting in a light dose of 4.5 Joules/cm2

Threeintravitreous VEGF inhibitors - aflibercept (Eylea, Regeneron Pharmaceuticals), bevacizumab (Avastin, Genentech), and ranibizumab (Lucentis, Genentech) - are commonly used for the treatment of diabetic macular edema causing vision impairment and have been shown to be beneficial and relatively safe. Study participants in the anti-VEGF group will be treated with intravitreous injections of one of these agents: afibercept (2.0 mg), bevacizumab (1.25 mg) or ranibizumab (0.5 mg) at appropriate intervals as determined by the treating ophthalmologist.
