Diabetic Retinopathy

What is Diabetic Retinopathy?

Diabetic retinopathy is a diabetes complication that affects the eyes. It’s caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). At first, diabetic retinopathy may cause no symptoms or only mild vision problems. However, it can eventually lead to blindness. The condition can develop in anyone who has type 1 or type 2 diabetes. The longer you have diabetes and the less controlled your blood sugar is, the more likely you are to develop this eye complication. Regular monitoring and maintaining good blood sugar control can help prevent its progression.

There are two main stages of diabetic retinopathy: non-proliferative (early) and proliferative (advanced). In the early stage, there are no vision problems and treatment may not be necessary. In the advanced stage, new blood vessels may grow in the retina and cause vision problems, including vision loss, blurriness, and floaters. Proliferative diabetic retinopathy causes profound and sometimes permanent changes in the vision as the retina is damaged.

Common Diabetic Retinopathy Symptoms

The symptoms of diabetic retinopathy include:

  • Blurred vision
  • Floating spots
  • Fluctuating vision
  • Dark or empty areas in vision
  • Poor night vision
  • Colours appear faded or washed out
  • Vision Loss

Diabetic Retinopathy Causes

Diabetic retinopathy is primarily caused by prolonged high blood sugar levels, leading to damage in the tiny blood vessels that serve the retina. As these vessels become blocked or leaky, the eye compensates by growing fragile new vessels. These new vessels can easily bleed, introduce fluids that swell the macula (central part of the retina), and even form scar tissue that may detach the retina. Furthermore, the nerve tissue in the eye can be affected, resulting in diabetic macular ischemia. Factors that exacerbate the risk include the duration of diabetes, how effectively it’s managed, concurrent high blood pressure and cholesterol, genetic factors, and other medical conditions. Proper management of diabetes and associated health parameters is crucial in mitigating the onset and progression of this eye complication.
