The Grading Module is a comprehensive dual-viewer for ophthalmologists who grade fundus images for diabetic retinopathy severity.

Dual-panel viewer

Side-by-side display of left and right eye, or current versus previous screening. Full zoom, pan, brightness, and contrast adjustment.

AI pre-grade overlay

The AI's suggested grade is shown as a starting point. The ophthalmologist confirms, adjusts, or overrides the AI assessment. The AI does not operate autonomously - ophthalmologist oversight is always maintained.

Multi-grader workflow

• First grader: initial assessment.
• Second grader: blinded review if required by local guidelines.
• Arbitration: senior ophthalmologist resolves disagreements.

Structured reporting

• Standardised grading forms based on the International Clinical DR Scale (5 levels), macular edema assessment, and image quality rating.

Compliance & quality

• Audit trail: every grading action is logged with timestamp, grader identity, and reasoning - full traceability for regulatory compliance.
• Worklist management: queue of images awaiting grading, priority sorting, deadline tracking.
• Grading statistics: per-grader accuracy, inter-grader agreement (kappa), turnaround time.
• DICOM compatibility: import and export in standard medical imaging format.
