Macular degeneration is a type of fundus lesion that seriously affects vision, including macular degeneration and hemorrhage caused by high myopia, age-related macular degeneration, central exudative retinopathy, macular hemorrhage and edema caused by various reasons, and there is no effective means to completely cure and restore normal. But it is not incurable, with the development of medicine, a large proportion of cases can still be effectively treated, which is of great importance to improve the quality of survival. Early treatment is of great importance for the prognosis. Early and correct treatment can preserve vision or improve it. Many patients do not pay attention or hesitate in the early stage and keep missing the time of treatment. As the lesion progresses, the death of retinal cells is irreversible, so the longer the time, the worse the effect. Medium-term treatment. As the lesion progresses, the necrosis of retinal cells and the formation of scars can lead to further loss of vision, making treatment difficult, but there is still a need for active treatment, which can preserve a large part of useful vision. Late stage treatment. If the lesion is completely scarred, the retinal cell function has been completely lost, the effect of treatment is very limited, whether or not to treat depends on your own decision, that is, the dead horse is a living horse.
