Each local diabetic eye screening service is required to have a single collated list (SCL) of all people in the local population who are eligible for screening.
This guidance is to help commissioners and provider organisations manage individuals not included on the SCL, including newly identified diabetic patients who were previously unknown to the screening service and should now be included on the list.
