Skip to 0 minutes and 11 secondsHello, and welcome to week two. This week, we explore the public health principles behind screening and how these are applied to prevent blindness from diabetic eye disease. We consider closely the key characteristics of screening tests, the statistical measures used to understand a good test from a poor test, and examine the screening challenges faced by health systems and the people with diabetes who undergo these tests. We share examples from the UK systematic screening programs, and we hope that this will initiate a discussion on what is feasible and practical for you within your own local context. As always, you can work through the materials in each step at your own pace and track your progress.

Skip to 1 minute and 5 secondsWe encourage you to join in the discussions at the end of each step and share your thoughts, views, and experiences as you go along.

Welcome to week 2

Diabetic retinopathy (DR) is one of the many complications of diabetes. Because there are no symptoms initially, patients will not realise they have the condition until it is at the proliferative stage or they develop macular oedema when their vision becomes affected.

To prevent vision loss, early detection is needed at the pre-proliferative stage. This can only be achieved if the person with diabetes has a regular (often annual) examination of their retina, starting from when they are first diagnosed. Diabetic retinopathy screening therefore has to be timely and in accordance with locally agreed guidelines for detection, referral and treatment.

By the end of this week you should be able to:

  • Describe and apply the principles of screening to diabetic retinopathy (DR)
  • Evaluate guidelines for screening and monitoring its implementation with the DR care pathway
  • Apply the DR planning toolkit to strengthen diabetic eye care services at a local level.
