The severity of macular degeneration in the eye is determined by the type of macular degeneration. As we age, the type of macular degeneration will show up in different forms. In young people, mesoplasia is common, which causes edema in the macular area, resulting in loss of vision and distortion of visual objects. In middle-aged people, macular edema and neovascularization are mainly caused by retinal vein obstruction or diabetes, which can also cause vision loss. In the elderly, macular degeneration and diabetic neovascularization are the main causes. Macular degeneration and neovascularization have a more serious impact on vision. Macular edema caused by retinal vein obstruction will cause vision loss, and vision will be improved faster after treatment. If the macular edema caused by middle pulp in young people is mild, it is self-healing, if it is severe macular edema, it needs active treatment, and the prognosis is also better.
