In case of macular zone lesions, in mild cases, there will be blurred vision, distorted vision, larger or smaller vision, and darkened vision; in severe cases, there will be edema and hemorrhage in the macular zone, and vision will be drastically reduced, or even completely blind. At present, the more effective eye drops for macular lesions are Sturgeon eye drops, also known as seven-leaf digitalis eye drops. Seven-leaf digitalis eye drops can improve the microcirculation of macular blood vessels by strengthening the vascular closure, reducing the permeability of blood vessels, reducing the leakage of macular blood vessels to promote the absorption of edema, eliminating the edema of macular area, and achieving the effect of improving vision and vision. It can be used four times a day and can be used for a long time.
