Everything you need after restoration.

Compare the source, quantify visible changes, and inspect regions before you write a report.

Image

Restore the source

Start with a fundus photograph. RRIN creates a cleaner version for side-by-side review.

Analysis

Measure what changed

See lesion counts, area estimates, quadrant distribution, and image quality in one place.

Review

Inspect before you report

Click into regions, compare outputs, and keep the evidence next to the finding.
