<b>Introduction</b> <p>UoA-DR database is created as part of the research being carried out at the University of Auckland aimed at developing an automatic screening system to screen patients affected by Diabetic Retinopathy (DR). This database was developed in collaboration with three hospitals in India Al-Salama Eye hospital, Dr. Tony Fernandez Eye Hospital, and Giridhar Eye Institute. The database consists of 200 retinal images mostly affected with diabetic retinopathy.</p> <p>This database also contains the manually segmented features. These are: retinal vessels, optic discs and fovea, which can be used as a ground truth for other retinal image processing algorithms. Also, for each image in this database, the optic disc center and fovea center locations are identified manually. Medical diagnosis is provided for each image based on guidelines provided by the International Clinical Diabetic Retinopathy scale.</p> <p> </p> <p><b>Contents of the Database</b></p> <p>The following materials are included in the database</p> <p>Retinal images: 200 images taken by Fundus camera </p> <p>Images resolution: 2124 x 2056 pixels </p> <p>Extracted features: 3 per image (Retinal Vessels, Optic disc boundary and center, Fovea center location) </p> <p>Excel files: 2 (DR Classification and OD Fovea Index)</p> <p>PDF file: 1 (UoA-DR diabetic retinopathy severity classification.pdf)</p> <p>Database size ≈ 500MB</p> <p> </p> <p><b>Database Download</b></p> <p>UoA-DR database is available freely to researchers or research units on a case-by-case basis. All requests must be submitted through email to the research investigators by any researcher, institution, academic, or research unit head.
