Verification of DR/Glaucoma ZIPs

This guide explains the verification process for Diabetic Retinopathy (DR) and Glaucoma ZIP archives uploaded from REMEDIO and compatible camera systems.

Overview

After ZIP files are uploaded and processed, they create patient encounters with DR and/or Glaucoma reports. The verification process ensures that all screening data is properly captured, validated, and made available for grading.

Accessing Verification Tools

Required Permissions

  • Admin: Full access to all verification tools
  • Data Manager: Access to encounters within assigned lab units
  • Optometrist: Access to verification for assigned encounters
  1. Log in to the system
  2. Navigate to Verify DR in the main menu
  3. View the list of DR reports organized by date
  4. Click on any report to view or edit details
  1. Log in to the system
  2. Navigate to Verify Glaucoma in the main menu
  3. View the list of Glaucoma results organized by date
  4. Click on any result to view or edit details

DR Verification Process

Step 1: Locate DR Reports

  1. In the DR verification list, browse reports by date
  2. Use filters to show:
  3. All reports
  4. Only verified reports
  5. Only unverified reports
  6. Click "Recent Unverified" to jump to the latest date with unverified reports

Step 2: Review Report Details

When viewing a DR report, check: - Patient Information: ID, examination date - Report Results: Qualitative and quantitative results - Images: All fundus images included in the encounter - PDF Reports: The original DR screening report

Step 3: Edit Report Information

In edit mode, you can: - Update patient ID - Modify capture date - Adjust result values - Mark image laterality (right/left/cannot tell)

Step 4: Verify the Report

After ensuring all information is correct: 1. Click the Verify button 2. The system will: - Mark the encounter as verified - Record who verified it and when - Automatically create grading tasks for all images - Add images to the DR grading queue

Glaucoma Verification Process

Step 1: Locate Glaucoma Results

  1. In the Glaucoma verification list, browse results by date
  2. Use filters to show:
  3. All results
  4. Only verified results
  5. Only unverified results
  6. Click "Recent Unverified" to jump to the latest date with unverified results

Step 2: Review Result Details

When viewing a Glaucoma result, check: - Patient Information: ID, examination date - VCDR Values: Vertical Cup-to-Disc Ratio for right and left eyes - Report Results: Qualitative and quantitative results - Images: All fundus images included in the encounter - PDF Reports: The original Glaucoma screening report

Step 3: Edit Result Information

In edit mode, you can: - Update patient ID - Modify capture date - Adjust VCDR values (numeric format) - Update result classifications - Mark image laterality (right/left/cannot tell)

Step 4: Verify the Result

After ensuring all information is correct: 1. Click the Verify button 2. The system will: - Mark the encounter as verified - Record who verified it and when - Automatically create grading tasks for all images - Add images to the Glaucoma grading queue

Image Laterality Tagging

Why It's Important

  • Ensures proper image identification for grading
  • Required before verification can be completed
  • Helps graders understand which eye they're evaluating

How to Tag Images

  1. In the edit view, locate each image
  2. Select the appropriate laterality:
  3. Right: Right eye (OD)
  4. Left: Left eye (OS)
  5. Cannot Tell: When laterality cannot be determined
  6. The system saves your selection automatically

Verification Requirements

  • All images must be tagged with laterality before verification
  • The system will prevent verification if any images are untagged
  • You'll see a warning message if images need tagging

Verification Status Management

Verifying Encounters

  • Marks the encounter as reviewed and approved
  • Creates grading tasks for all images
  • Records verifier identity and timestamp
  • Makes images available in the grading queue

Unverifying Encounters

  • Removes verification status
  • Deletes pending grading tasks (only if tasks are still pending)
  • Allows for corrections and re-verification
  • Requires appropriate permissions

Verification History

  • System tracks who verified each encounter
  • Timestamps are recorded for audit purposes
  • Recent verification history is available for each user

Common Verification Issues

Missing Image Laterality

  • Symptom: System prevents verification with message about untagged images
  • Solution: Tag all images with appropriate laterality before verifying

Invalid Data Values

  • Symptom: System rejects invalid VCDR values or other data
  • Solution: Ensure all numeric values are within valid ranges

Access Denied

  • Symptom: Cannot access verification for certain encounters
  • Solution: Check that you have permissions for the lab unit

Tasks Already in Progress

  • Symptom: Cannot unverify because grading has started
  • Solution: Contact graders to complete or release tasks

Best Practices for Verification

  1. Systematic Review: Follow the same review process for each report
  2. Image Quality Check: Ensure images are clear and show required structures
  3. Data Validation: Double-check all numeric values and classifications
  4. Complete Tagging: Tag all images before attempting verification
  5. Documentation: Add notes for any unusual findings or issues

Integration with Grading Workflows

Automatic Task Creation

  • Verification automatically creates grading tasks
  • Tasks are assigned to the appropriate disease (DR or Glaucoma)
  • All images in the encounter receive grading tasks

Quality Assurance

  • Verified encounters have priority in grading queues
  • Verification status is visible to graders
  • Graders can access verification details for context

Data Cleaning (Glaucoma Only)

The Glaucoma module includes a data cleaning workflow: - Extracts numeric VCDR values from text fields - Stores cleaned values in a separate table - Maintains original values for reference - Provides metrics on cleaning effectiveness

Reporting and Analytics

Verification Statistics
