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. In this study, the efficacy and safety of PBM with near-infrared radiation in a patient with diabetic macular edema were assessed. We present the case of a 60-year-old man with diabetic macular edema responding to 670 nm light PBM alone. 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. 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.
黄斑水肿是糖尿病患者视力下降的主要原因。近红外光辐照的光生物调节（PBM）具有抗氧化和抗炎作用。在这项研究中，评估了近红外光 PBM 在糖尿病性黄斑水肿患者中的疗效和安全性。我们报告了一例 60 岁男性糖尿病性黄斑水肿患者，仅对 670nm 光 PBM 有反应。PBM 后，他的视力提高，黄斑水肿在光学相干断层扫描（OCT）检查结果中得到解决，没有不良反应。在 16 个月的随访中，视力保持稳定，OCT 显示无水肿复发迹象。670nm 光 PBM 可被视为治疗糖尿病性黄斑水肿患者的一种潜在方法。此外，它还可以提供一种非侵入性和非昂贵的家庭治疗方法。
