The best treatment is to prevent the development of retinopathy as much as possible.  Strict control of your blood sugar will significantly reduce the long-term risk of vision loss from diabetic retinopathy.  If high blood pressure and kidney problems are present, they need to be treated.    
                 
                Laser Surgery is often recommended for people with macular edema, PDR and neovascular glaucoma.   

                For macular edema, the laser is focused on the damaged retina near the macula to decrease the fluid leakage.  The main goal of treatment is to prevent further loss of vision.  It is uncommon for people to have blurred vision from macular edema to recover normal vision, although some may experience partial improvement.  A few people may see the laser spots near the center of their vision following treatment.  The spots usually fade with time but may not disappear.

                For PDR, the laser is focused on all parts of the retina except the macula.  This panretinal photocoagulation treatment causes abnormal new vessels to shrink and often prevents them from growing. In the future.  It also decreases the chance that vitreous vleeding or retinal distortion will occur.     

                Multiple laser treatments over time are some times necessary.  Laser surgery does not cure diabetic retinopathy and does not always prevent further loss of vision.

Diabetes (Diabetic Retinopathy) Treatment

Diabetes (Diabetic Retinopathy)

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.   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.  The leaking fluid causes the retina to swell or to form deposits called exudates.  Many people have mild NPDR, which usually does not affect their vision.  When vision is affected it is the result of macular edema, macular ischemia (, or both.  Macular edema is the swelling or thickening of the macula which is the small area in the center of the retina that allows us to see fine details clearly.  The swelling is caused by fluid leaking from retinal blood vessels.  It is the most common cause of visual loss in diabetes.  Vision loss may be mild to severe, but even in the worst causes, peripheral vision continues to function.  Macular Ischemia occurs when small blood vessels (capillaries) close.  Vision blurs because the macula no longer receives sufficient blood supply to work properly.
                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 abnormal new 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.
