Information About Diabetic Retinopathy

We Have to Know about the Diabetic Retinopathy

  • Retinopathy refers to diseases that affect the retina
  • Abnormalities in the blood vessels can cause several forms of retinopathy.
  • Retinopathy can cause partial loss of vision or complete blindness.
  • It can develop slowly or occur suddenly.
  • Diabetic retinopathy develops in people with diabetes

Could be dangerous, if the answer is YES for any one of the following questions

  • Is there a sudden loss of vision?

Causes of Diabetic Retinopathy

  1. Nonproliferative retinopathy– existing blood vessels in the retina deteriorate. Deteriorating blood vessels can become blocked or can develop balloon-like deformities called aneurysms. Fluids, fats, and proteins leak out of the abnormal blood vessels. Fluid can collect in the area of the retina that is responsible for sharp vision (the macula). Macular swelling (edema) impairs the fine vision necessary for reading and detail work.
  2. Proliferative retinopathy- new blood vessels grow on the surface of the retina and cause frequent small bleeding, causing local irritation with scar formation. In these scar areas vitreous adhere to the retina and distort its shape and cause a pull. This force can pull apart the layers of the retina so that the retina can’t function. This separation of layers is known as retinal detachment Sudden bleeding into the vitreous also can obscure vision, often quite suddenly

Do’s and Don’ts –Diabetic Retinopathy

  • Control blood sugar and blood pressure are essential to prevent diabetic retinopathy
  • Annual eye exams are crucial for people with diabetes. If an abnormality is discovered during an exam, treatment can start before sight is affected and can delay vision impairment

Signs & Symptoms of Diabetic Retinopathy

  • Blurred vision
  • Sudden loss of vision in one or both eyes
  • Black spots
  • Flashing lights
  • Difficulty reading or seeing detailed work

Medical advice for Diabetic Retinopathy

Treatment for Diabetic Retinopathy

  • To keep diabetic retinopathy from getting worse, blood sugar and blood pressure must be controlled to avoid complications
