Diabetic eye screening is a test to check for eye problems caused by diabetes, eye problems caused by diabetes are called diabetic retinopathy. This can lead to sight loss if it's not found early. The eye screening test can find problems before they affect your sight. Pictures are taken of the back of your eyes to check for any changes.

Diabetes screening tests are also advisable for people with a number of risk factors for type 2 diabetes such as being overweight or obese, having a close family member with type 2 diabetes or being of African-Caribbean, Middle Eastern or South Asian origin. Screening for gestational diabetes should either  occur between weeks 24 and 28 weeks of pregnancy or, if you have had gestational diabetes in a previous pregnancy, between 16 and 18 weeks and, if negative, followed by a second test at 28 weeks.
