The Fundus Photo Viewer is a comprehensive viewing tool for research and education. It is not used for clinical grading - it is designed for learning, training, and research purposes.

Target audience

Screeners in training, medical students, residents, researchers, and instructors.

Powerful dual-viewer

The same dual-panel viewer as the Grading Module - side-by-side comparison, full zoom and pan, brightness and contrast controls - but without the clinical grading workflow.

Educational features

• Educational overlays: toggle pathology annotations, DR severity explanations, and comparison with reference images.
• Case library: browse de-identified cases organized by DR grade, pathology type, and image quality.
• Teaching mode: instructors can create quizzes ("What grade is this image?") with immediate feedback.
• Self-assessment: graders can practice and track their own agreement with expert grades (kappa score).
