The answer is no. Diabetic retinopathy, is the ocular manifestation of diabetes, which develops in patients at a certain point. The main manifestations are hemorrhage in the fundus, proliferative membrane and non-perfused areas. Depending on the condition of the garden, it is divided into six stages. The first three stages are the non-proliferative stage, which is mainly characterized by the appearance of tiny hemorrhagic spots edema and punctate hemorrhage. The last three stages are proliferative stage, appearing as proliferative membrane fundus imaging sees a large number of nonperfused areas, forming neovascular proliferation, and finally appearing as retinal detachment by traction. Therefore, after controlling the underlying diabetes, diabetic retinopathy should be strictly given to fundus laser treatment before the third stage. This prevents further fundus lesions and neovascularization, which can cause permanent vision loss. Fundus laser treatment is an invasive treatment for the fundus of the eye. Localized necrosis of the photoreceptors will occur, and the corresponding darkening and loss of visual field will occur, but the advantages outweigh the disadvantages, because once neovascularization occurs, it will quickly cause neovascular disease, manifesting as secondary diseases such as hemorrhagic blindness and high intraocular pressure, and eventually loss of vision. Therefore, early and selective retinal laser photocoagulation therapy should be given. Strict control of blood glucose and regular review of ophthalmology are required to achieve the goal of slowing down the progression of the disease.
