The data consists of various parts:

1. 1120 fundus color images (4 fields per eye, 2 eyes per subject, 2 exams per subject; PNG files).
2. 1120 normalized images (greyscale PNG files).
   
3. 280 intra-visit mosaics (image; PNG and movie; AVI)
   
4. 280 inter-visit mosaics (movie; AVI)
5. Patient information and all grades/ranks assigned by the graders (CSV)
   

Because the total data set is rather large (4.6 GB), we also provide a small subset of the image/movie data. This allows you to quickly check whether the data is of use to you. Please select the file you would like to download.

• Subset of data, containing all grades/ranks and images/movies of 4 eyes (132 MB).
