Diabetic retinopathy is the most common form of diabetic eye disease that affects both eyes. The risk of progressing diabetic retinopathy is known to upsurge with age as well with uncontrolled blood sugar, very high blood sugar symptoms or hyperglycemia, blood glucose levels in the prediabetes range and unregulated blood pressure level. If left untreated, diabetic retinopathy can cause blindness.

Diabetic retinopathy in simple terms is referred to as a diabetic condition that impacts the eyes. It is caused when the blood sugar level is alarmingly high in the human body. High blood sugar levels damage the blood vessels in the retina, which allows visualization. They can cause the blood vessels to swell, leak and even block blood from flowing smoothly. The condition may occur among people with both, Type 1 and Type 2 diabetes.

Usual and most common symptoms of diabetic retinopathy are:

  • Vision disorder- the patient will have difficulties in visualizing and other eye related diseases may occur, which require corrective lenses and spectacles to restore proper vision.
  • Blurred vision- the patient will not be able to see properly
  • Distorted vision- the patient may view clearly but will definitely miss a clear horizon or up and down type of vision/images
  • Impaired colour vision- the person will have difficulties identifying colours
  • Spots- occur in the eye balls, maybe back or dark red.
  • Vision loss- the patient will completely lose the ability to visualization, such as in glaucoma.

The patient must control his or her blood sugar and take precautions naturally. In addition, on elevated conditions may consult the doctor for effective treatment. Common drugs to treat diabetic retinopathy are:

  • Intravitreal aflibercept (Eylea) and 
  • Ranibizumab (Lucentis).
