[Laser photocoagulation treatment of diabetic maculopathy].

Diabetic retinopathy is the main cause of decreased visual acuity in non-proliferative or proliferative diabetic retinopathy. The frequency of maculopathy rises with age and the duration of diabetes, and now represents the major therapeutic problem following the control of neovascular proliferation through pan-retinal photocoagulation. Oedematous maculopathy, focal or diffuse, and cystoid macular oedema are improved by laser photocoagulation, either focal or grid. Laser photocoagulation is not indicated for predominantly ischaemic maculopathy. The laser treatment should be carried out early in the stage of clinically significant oedema, and applied either focally or in a grid depending on the clinical and angiographic features of the diabetic maculopathy. If pan-retinal photocoagulation is also indicated it should be performed after the focal macular treatment. Laser treatment should always be accompanied by a general medical assessment, emphasising optimal glycemic control and control of associated risk factors, especially arterial hypertension.
