IPM Take
The sharp signal is that screening is no longer just about inviting everyone at the same interval. England is trying to use risk more intelligently: lower-risk patients can be screened less often, while higher-risk findings are channelled into more targeted surveillance and hospital referral. That is sensible for capacity, but it creates a fairness test. Risk-based screening only works if programmes monitor whether some groups, including younger people and ethnic minority communities, are disadvantaged by longer intervals.
Executive Summary
A 2026 Eye Open review describes recent changes in the English NHS Diabetic Eye Screening Programme. These include two-yearly screening for certain low-risk groups, refinement of the R2 grade into low-risk and high-risk categories, and introduction of an Optical Coherence Tomography surveillance pathway. The UK National Screening Committee states that people aged 12 and over with diabetes who have had two consecutive screens showing no diabetic retinopathy can be offered screening every two years instead of every year.
Why it matters
- Public authorities: Need to show that risk-based screening protects capacity without delaying detection for groups at higher risk.
- Clinicians / hospitals: Should prepare for more differentiated referral routes, including OCT-supported surveillance and clearer thresholds for hospital eye service review.
- Patients / advocates: Should track whether longer intervals are communicated clearly and whether people know when to seek care between screening invitations.
Previously, diabetic eye screening in England invited every person with type 1 or type 2 diabetes annually. That universal rhythm helped reduce diabetic retinopathy-related blindness, but rising diabetes prevalence, workforce pressure and hospital eye service demand made the model harder to sustain.
What has changed is the move toward more differentiated screening. Low-risk patients with two consecutive negative screens may move to two-yearly invitations. The R2 category has been refined into lower-risk and higher-risk groups, and OCT surveillance can help decide which maculopathy cases need hospital eye service referral. The Eye Open review presents these changes as a response to growing programme pressure and the need to use specialist capacity more efficiently.
The affected population is people with diabetes who are eligible for eye screening, particularly those whose screening interval or referral pathway may change. This is not a reduction in screening for everyone. Higher-risk patients should continue to receive more frequent monitoring or referral.
For IPM, the implementation message is direct: risk-based screening can protect capacity and reduce unnecessary appointments, but it must be monitored carefully. If longer intervals delay detection in some communities, the system will need to adjust.
