The current treatment for diabetic retinopathy is mainly laser therapy, which can stop the formation of retinal neovascularization and prevent the development of retinopathy, thus saving further deterioration of vision. If the lesion is too severe to be treated with retinal photocoagulation, if there is a lot of bleeding in the fundus, or if a proliferative membrane is formed in front of the retina and the retina detaches, early surgery is needed to remove the cloudy vitreous and peel off the proliferative membrane to reset the retina. The onset of diabetic eye disease is a slow process, and early symptoms may not be obvious, but once obvious symptoms appear, it means that the complications have been there for some time. Therefore, it is important for diabetic patients to have their vision and fundus checked regularly at the ophthalmology department for early detection and treatment to avoid serious damage to their vision and to improve their quality of life.
