Abstract Purpose:To evaluate the efficacy of 577 nm subthreshold micropulse laser with navigation system on refractory diabetic macular edema.

Methods:Retrospective observational case series. Sixteen eyes of 14 patients with prolonged macular edema after prior treatment with anti-VEGF therapy, steroid injection, or vitrectomy were followed for 3 months after subthreshold laser treatment. Visual acuity and central foveal thickness on the images of optical coherence tomography were measured.

Results:Mean logMAR was 0.3±0.3 before laser treatment and 0.3±0.4 three months after treatment(p=0.51). There was no eye with decrease in visual acuity during follow-up. Mean central foveal thickness(CFT)significantly decreased to 342.4±189.3 μm at 3 month after treatment from 412.5±152.3 μm before treatment(p=0.02). Ten of 16(63%)eyes showed over 20% decrement of CFT compared to that before treatment. No eyes showed retinal damage on fundus autofluorescence images.

Conclusion:577 nm subthreshold laser has potential efficacy on refractory diabetic macular edema.
