Macular edema is a common cause of visual loss in patients with retinal vascular diseases represented by diabetic retinopathy and retinal vein occlusion. Laser photocoagulation has been the main treatment for this kind of diseases for decades. With the advent of antagonist of vascular endothelial growth factor and dexamethasone implant, diabetic macular edema and macular edema secondary to retinal vein occlusion have been well controlled; the use of laser therapy is decreasing. However, considering possible risks and complications, lack of extended inspection of efficacy and safety of intravitreal pharmacotherapy, laser therapy cannot be replaced by now. Therefore, the efficacy and safety of laser therapy will improve by sober realization of role of photocoagulation and proper selection of treatment indication.
