If you have been diagnosed with diabetes, you may be at risk of losing your vision since your body does not utilize sugar properly and, when the sugar levels rise, damage to the retinal blood vessels may occur. Diabetic retinopathy is a potentially blinding complication of diabetes that damages the eye’s retina. Diabetic Retinopathy is the leading cause of blindness in working-age adults. Often, one may not be aware of any symptoms even when significant diabetic retinopathy is present. In Fig. If abnormal new blood vessels form, as in proliferative diabetic retinopathy, they may bleed and result in small specks or large floaters obscuring the vision. If abnormal new blood vessels form, as in proliferative diabetic retinopathy, they may bleed and result in small specks or large floaters obscuring the vision.
A comprehensive eye examination by an optometrist or retina specialist is the only reliable means of detecting diabetic retinopathy. Proliferative retinopathy can develop without symptoms. If diabetic retinopathy is discovered, a fluorescein dye test and/or optical coherence tomogram (OCT) may be recommended. A fluorescein angiogram involves the injection of a dye into a vein in the arm followed by several minutes of intermittent photos with a special digital camera focused on the retina. Severe vision loss is preventable in the vast majority of cases, and can possibly be improved. The body no longer is able to use insulin properly. Studies show that strict control of blood sugar levels can significantly lower the risk of vision loss from diabetic retinopathy.
What is the treatment for diabetic retinopathy? Laser surgery is often the first line of treatment if macular edema or proliferative retinopathy is present. For macular edema, the laser is focused on leaky areas of the retina to aid in reabsorbing the excess fluid. Angiogenesis is a term used to describe the growth of new blood vessels and plays a crucial role in the normal development of body organs and tissue. 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 blood vessels do not supply the retina with adequate blood flow. Injectable medications may also help reduce swelling and inflammation, and can be combined with laser therapy for the best results.
