Longitudinal diabetic retinopathy screening data

Type: Dataset

abstract= {This data set contains
repeated 4-field color fundus photos (1120 in total) of 70 patients in the diabetic retinopathy screening program of the Rotterdam Eye Hospital (Rotterdam, The Netherlands);
the result of intra- and inter-visit registration by two methods (i2kRetina and WeVaR); and
the grading and ranking of these results by two graders.

### Inclusion criteria:
All patients with diabetes who were screened for diabetic retinopathy during one week in June 2013.

### Exclusion criteria:
First-time patients and
Patients who were not examined in the year before.

Fundus image of both eyes of each patient were acquired using a non-mydriatic digital fundus camera (Topcon TRC-NW65) with a 45 degrees field of view after pupil dilation. Images of each visit were registered by two methods: WeVaR (see Adal et al, A Hierarchical Coarse-to-Fine Approach for Image Registration) and i2k Retina (DualAlign LLC; see here). Image mosaic movies were created from the registered, normalized fundus images and were presented to two graders. In addition, the graders compared the image mosaics side-by-side and ranked them. Images of consecutive visits were similarly registered and the image mosaic movies were again presented to two graders.

Included data:
Patient's gender and age
All color fundus images
All normalized fundus images
Intra-visit image mosaic movies for both registration methods
Intra-visit Image mosaics for both registration methods
Inter-visit image mosaic movies for both registration methods
Scores of two graders (not every movie/image was graded by both graders)
