Blurred vision in diabetes should first be treated for the primary disease, and eye surgery can be considered if conservative treatment is ineffective. Blurred vision in diabetes is most likely caused by high blood sugar, first of all, we should treat the primary disease, reduce the blood sugar to normal level, and the patient does not have any substantial disease in the eye, the vision will gradually improve, or even return to normal. If the patient’s vision still does not improve after controlling blood sugar, the doctor needs to examine the eye, if the lesion has occurred in the fundus, such as hemorrhage, macular degeneration, then the effect of conservative treatment is more limited, and we need to choose the appropriate surgical treatment, such as laser surgery and so on. If blurred vision in diabetes occurs, it is recommended to consult a doctor in time for treatment under the guidance of the doctor.
