Every diabetic should know Many diabetics do not realize that they will only have symptoms when diabetic retinopathy has become very severe and that treatment is most effective when symptoms are present, so by the time they are discovered, the disease is often already severe. In order to detect, control and delay the development of diabetic retinopathy early, every diabetic should know that: 1. Good control of blood glucose and blood pressure can reduce the damage of diabetes to the eyes. However, in practice, both type 1 and type 2 diabetics are unable to achieve strict blood sugar control and will eventually develop some diabetic changes. 2. Regular retinal examinations (such as fundus examination, fundus photography, fundus fluorescence angiography and optical coherence tomography) are necessary to detect diabetic retinopathy. In the absence of obvious fundus lesions, the examination should be done once a year; if fundus changes have appeared, the interval between examinations should be shortened following medical advice. 3. Early detection, early treatment and regular checkups can significantly reduce the chance of blindness. Timely and appropriate laser treatment can delay and control the disease. 4.Modern treatment can help delay and control the disease, but cannot restore the lost vision. After the above introduction, we hope that each diabetic patient can pay attention to regular eye examination and timely treatment accordingly, control blood sugar and blood pressure, delay and control the development of blinding diabetic eye complications, and improve the quality of life.
