How EQA works
This platform is designed for structured diabetic retinopathy screening QA, retinal image education, and clinically meaningful reviewer feedback.
Structured image review
Grade assigned retinal images using the built-in clinical tools, structured grading fields, and practical lesion review controls.
Consensus and QA
Support consistency through shared grading workflows, comparison against consensus or gold standards, and structured QA review.
Feedback and improvement
Use progress, agreement, outcome, and ROC-oriented review pages to strengthen calibration and educational development over time.
EQA grading guidance
1. Review the image first
Always inspect the retinal image carefully before grading, especially near the edge of the field.
2. Use the image tools
Zoom, black & white, negative, and contrast controls can reveal subtle lesions more clearly.
3. Use the fovea / disc tool
Distance from the fovea matters. Use the built-in tool when lesion position relative to disc diameters is important.
4. Grade visible disease even in poor images
If clearly referable disease is visible, it should still be graded even if overall quality is reduced.
5. Use masks for training review
Saved annotation boxes help highlight lesions, support education, and make later review more useful.
6. Learn from consensus and feedback
Use question-level, field-level, and ROC-style review outputs to improve calibration and consistency over time.
Frequently asked questions
What is the purpose of External Quality Assurance?
EQA promotes consistency in retinal screening and grading. It supports education, confidence, professional development, and cross-centre alignment of outcomes.
How is EQA organised?
Graders work through shared or equivalent image sets and structured tests during a defined assessment period, allowing results to be compared and reviewed consistently.
What feedback will I receive?
Depending on your workflow, you can review progress, agreement, referable outcomes, field breakdowns, and ROC-style performance summaries after grading.
