Diabetic retinopathy is a condition occurring in persons with diabetes, which causes progressive damage to the retina, the light sensitive lining at the back of the eye. It is a serious sight-threatening complication of diabetes.
Diabetes is a disease that interferes with the body’s ability to use and store sugar, which can cause many health problems. Too much sugar in the blood can cause damage throughout the body, including the eyes. Over time, diabetes affects the circulatory system of the retina.
Diabetic retinopathy is the result of damage to the tiny blood vessels that nourish the retina. They leak blood and other fluids that cause swelling of retinal tissue and clouding of vision. The condition usually affects both eyes. The longer a person has diabetes, the more likely they will develop diabetic retinopathy. If left untreated, diabetic retinopathy can cause blindness.
Symptoms of diabetic retinopathy include:

  • Seeing spots or floaters in your field of vision
  • Blurred vision
  • Having a dark or empty spot in the center of your vision
  • Difficulty seeing well at night-  American Optometric Association

DR screening software performs well in clinical tests

An automated screening system for grading diabetic retinopathy (DR) patients for referral is ready to progress to clinical use following positive preliminary study results.
A validation study, involving 627 patients, compared automated grading using IDx-DR software against three independent retina experts. The grading software, which was granted a CE mark in 2013, showed high sensitivity and specificity, 87% and 89% respectively. 
Primary investigator of the study,Professor Giel Nijpels, of the EMGO institute at VU University Medical Centre Amsterdam, said: “Current screening methods for diabetic retinopathy are becoming quite costly due to the rising prevalence of diabetes. Based on these results and the easy implementation in our daily clinical practice, I’m convinced that automated detection is a safe and cost-effective method providing a breakthrough in [diabetic retinopathy]-screening.” ….
