Diabetic retinopathy is an eye disorder that can affect people with diabetes. When this happens, elevated blood sugar levels harm the retina's blood vessels. They have the potential to expand and leak. Alternately, they could close, preventing blood flow. On the retina, abnormally new blood vessels can occasionally form. These various changes may rob you of your vision. The more severe stage of diabetic eye disease is called PDR. When the retina begins to sprout new blood vessels, it occurs. The term for this is neovascularization. The vitreous frequently bleeds into these tender new vessels. You might notice a few dark floaters if they only slightly bleed. They may lose all vision if they bleed profusely. The tissue created by these new blood vessels may scar. Scar tissue has the potential to damage the macula or result in a detached retina.
