Laser photocoagulation continues to be the treatment of choice in conjunction with the use of steroids and anti-angiogenics, but these treatments include possible ocular complications. The nutritional supplement Alzer (whose primary active ingredient is Ginkgo biloba, a powerful antioxidant that acts on vascular factors and oxidative damage, which are two of the mechanisms implicated in the pathogenesis of diabetic macular edema), which has been used on other non-diabetic macular conditions, along with the Diamel nutritional supplement has been shown to be effective on glycemic control and could represent a treatment alternative for mild to moderate macular edema by reducing the thickness of the macular retina and preventing the progression of other more advanced clinical presentations that are harder to treat. Objective: Identify the effect of Alzer along with Diamel in reduction of the thickness of the macular retina among patients with mild to moderate diabetic macular edema. Materials and Methods: A phase II double-blind clinical trial was conducted in 64 patients with non-severe diabetic macular edema over the course of non-proliferative diabetic retinopathy, who attended the ophthalmology service of the Institute of Endocrinology of Havana from January 2016 to December 2016. The treatment was randomly assigned to two groups: one received Alzer plus Diamel (n = 32) and the other group received Alzer placebo + Diamel placebo (n =
