Diabetes Can Affect Sight
If you have diabetes mellitus, your body does not use and store sugar properly. High blood-sugar levels can damage blood vessels in the retina, the nerve layer at the back of the eye that senses light and helps to send images to the brain. The damage to retinal vessels is referred to as diabetic retinopathy.
Types of Diabetic Retinopathy
There are two types of diabetic retinopathy - nonproliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR).
NPDR, commonly known as background retinopathy, is an early stage of diabetic retinopathy. In this stage, tiny blood vessels within the retina leak blood or fluid that causes the retina to swell or to form deposits called exudates.
PDR is present when abnormal new vessels (neovascularization) begin growing on the surface of the retina or optic nerve. The main cause of PDR is widespread closure of retinal blood vessels, preventing adequate blood flow. The retina responds by growing new blood vessels in an attempt to supply blood to the area where the original vessels closed. Unfortunately, the new, abnormal blood vessels do not resupply the retina with normal blood flow. The new vessels are often accompanied by scar tissue that may cause wrinkling or detachment of the retina. PDR may cause more severe vision loss than NPDR because it can affect both central and peripheral vision.
Diagnosing Diabetic Retinopathy
A medical eye examination is the only way to detect changes inside your eye. The doctors of Eye Surgical Associates can often diagnose and treat serious retinopathy before you are aware of any vision problems. The ophthalmologist determines your risk by dilating your pupil and looking inside your eye with an ophthalmoscope. If a diagnosis of diabetic retinopathy is made, a treatment plan will be prescribed.
