Here is an article about a vast group of diabetic patients had been treated for comparison for techniques for treatment of diabetic macular edema. Diabetes is a metabolic disorder characterized by hyperglycemia or high blood sugar and other signs, as distinct from a single illness or condition.

The scientist and researchers recognizes three main forms of diabetes, type 1, type 2, and gestational diabetes which occurs during pregnancy, also which have similar signs, symptoms, and consequences, but different causes and population distributions. Eventually, all forms are due to the beta cells of the pancreas being unable to produce sufficient insulin to prevent hyperglycemia. Type 1 is usually due to autoimmune destruction of the pancreatic beta cells, which produce insulin. This can be clearly seen under a digital microscope. And Type 2 is characterized by tissue-wide insulin resistance and varies widely; it sometimes progresses to loss of beta cell function. Diabetes can also cause several complications. Acute complications hypoglycemia, ketoacidosis or nonketotic hyperosmolar coma may occur if the disease is not adequately controlled. Serious long-term complications include cardiovascular disease, chronic renal failure, diabetic nephropathy is the main cause of dialysis in developed world adults, retinal damage which is said can lead to blindness and is the most significant cause of adult blindness in the non-elderly in the developed world, nerve damage of several kinds, and microvascular damage, which may cause erectile dysfunction or impotence and poor healing. You can see this under a digital microscope.

Poor healing of wounds, particularly of the feet, can lead to gangrene which can require amputation the leading cause of non-traumatic amputation in adults in the developed world. Adequate treatment of diabetes, as well as increased emphasis on blood pressure control and lifestyle factors, such as not smoking and keeping a healthy body weight, may improve the risk profile of most aforementioned complications that can be seen under a digital microscope. Diabetic retinopathy often has no early warning signs as they say. Even macular edema, which may cause vision loss more rapidly, may not have any warning signs for some time. In general, however, a person with macular edema is likely to have blurred vision, making it hard to do things like read and drive. In some cases, the vision will get better or worse during the day. Macular edema occurs when fluid and protein deposits collect on or under the macula of the eye, a yellow central area of the retina, causing it to thicken and swell. This can be clearly seen under a digital microscope.

The swelling may distort a person’s central vision, as the macula is near the center of the retina at the back of the eyeball. This area holds tightly packed cones that provide sharp, clear central vision to enable a person to see form, color, and detail that is directly in the line of sight. In their study they have gathered around two hundred subjects with previously untreated diabetic macular edema and had a result those 12 months after treatment, their technique was less effective at reducing optical coherence tomography measured retinal thickening than the more extensively evaluated current modified laser photocoagulation approach. Having known these results, a larger long-term trial of their technique is not justified as of now. More on this topic
