We often find patients with severe diabetic retinopathy in our outpatient clinics, and whenever this happens, both I and my colleagues will be very distressed and chastise the patients, saying, “Why are you only coming now? Why are we so distressed? It is because diabetic retinopathy can have a good outcome if treated in time. But if the patient does not understand this disease, can’t consult the doctor in time, wait until after the loss of vision or even intraocular hemorrhage, some patients have lost the best time for treatment, despite the many surgeries done will also have good vision again, loss of ability to work and a good quality of life. Therefore, it is important for everyone to understand diabetes and its complications. If a diabetic patient does not have good control of blood sugar, diet, high blood cholesterol and high blood pressure, then the patient has a high chance of getting retinopathy. Retinopathy is a type of microangiopathy in diabetic patients and may be accompanied by microangiopathy in other areas, such as diabetic nephropathy due to microangiopathy in the kidneys. It may also be associated with diabetic heart disease, and in some patients it is a painless heart attack that leads to life-threatening conditions. Diabetic patients may also suffer from intracranial lacunar infarction and other cardiovascular diseases. Therefore it is important to control blood sugar. You must seek help from an endocrinologist to get a treatment plan that suits you. And review it on time to adjust the treatment plan at any time. How can diabetic patients be monitored for the development of diabetic retinopathy? Patients who have had the disease for ten years may develop fundopathy if their blood sugar is not well controlled. Therefore, patients should visit the ophthalmologist for regular checkups after diabetes is detected. Depending on the fundus examination, the doctor will ask for a review once a year if the fundus is in good condition. If a small amount of microangioma is found in the fundus, a six-monthly review will be requested. If it is more severe then a one to three month review is requested. In some of these patients, the doctor will order a fundus fluoroscopy to determine whether to proceed with laser treatment. However, some patients think that everything is fine after laser treatment and do not come to the hospital for follow-up. Then one day some patients will find that they suddenly can’t see. There are two possible reasons for this: one could be an intraocular hemorrhage, and some people need very complicated surgery to get the condition under effective control. The second could be neovascular glaucoma, where once vision is lost it can never be regained. That is why we strongly promote and call on diabetic patients to have regular fundus examinations to detect the lesions in time for laser treatment. After laser treatment, not one time or one course of laser treatment can solve all the problems! Be sure to still have regular follow-ups after laser treatment so that your doctor can evaluate the effectiveness of laser treatment in a timely manner, and some patients still need supplemental laser treatment. The occurrence and development of fundus lesions are closely related to poor control of blood sugar. So be sure to control blood sugar well. Be sure to check the fundus regularly. Only in this way can we detect fundus lesions in time, treat them with laser in time, and review them regularly to maintain good vision. Never to the time of vitreous hemorrhage vision loss, in the emergence of neovascular glaucoma to go blind, both labor and injury, and then regret may have been too late. Diabetic patients should cherish ah!
