Clinical Scorecard: Keeping an Eye on Diabetes

At a Glance

Key Highlights

• DESP has significantly reduced diabetic eye disease as a leading cause of blindness among working-age adults in England since 2003.
• Screening uptake remains high (~82.7%), but challenges persist in younger adults and equity across ethnic groups.
• Recent reforms include risk-stratified screening intervals, OCT implementation, and planned integration of AI-based automated retinal image analysis.

Guideline-Based Recommendations

Diagnosis

• Annual digital retinal screening offered to all people with diabetes aged 12 and over.
• Use of digital surveillance (DS) and slit lamp bio-microscopy (SLB) as part of screening pathways.
• Implementation of optical coherence tomography (OCT) in DS clinics for precise disease stratification.

Management

• Timely referral to ophthalmology for urgent and routine cases based on screening results.
• Treatment options include intravitreal anti-VEGF injections, steroid therapies, laser treatment, and vitrectomy.
• Risk-stratified screening intervals with 2-yearly screening for low-risk patients after two consecutive negative screens (R0M0).

Monitoring & Follow-up

• Continuous monitoring of screening uptake and referral outcomes.
• Performance metrics for referral timescales and coverage standards updated in 2024.
• Ongoing evaluation of AI-based automated retinal image analysis systems for screening efficiency and accuracy.

Risks

• Delayed screening attendance, especially in younger adults (18–34 years).
• Equity concerns with higher risk of progression in South Asian and Black ethnic groups.
• Sustainability challenges due to rising diabetes prevalence and resource demands.

Patient & Prescribing Data

Screening identifies patients needing ophthalmic interventions; recent reforms optimize resource use and reduce unnecessary hospital appointments.

Clinical Best Practices

• Ensure annual screening attendance, with targeted efforts to engage younger adults and underserved populations.
• Adopt risk-stratified screening intervals to maintain cost-effectiveness without compromising safety.
• Incorporate OCT in surveillance clinics to reduce unnecessary hospital referrals.
• Prepare for integration of AI-assisted grading to improve screening capacity and accuracy while maintaining human oversight.
• Address workforce concerns through training and clear communication about AI roles.
