 **Retinal Fundus Multi-disease Image Dataset (RFMiD)** consists of 3200 fundus images captured using three different fundus cameras with 46 conditions annotated through adjudicated consensus of two senior retinal experts. To the best of our knowledge, our dataset, RFMiD, is the only publicly available dataset that constitutes such a wide variety of diseases that appear in routine clinical settings. 
 This dataset will enable the development of generalizable models for retinal screening.

+The RFMiD is a new publicly available retinal images dataset consisting of 3200 images along with the expert annotations divided into two categories, as follows:
+Screening of retinal images into normal and abnormal (comprising of 45 different types of diseases/pathologies) categories.
+Classification of retinal images into 45 different categories.
+The dataset is split into 3 subsets: training 60% (1920 images), evaluation 20% (640 images), and test 20% (640 images) sets. 
+The disease wise stratification on average in training, evaluation and test set is 60 ± 7 %, 20 ± 7%, and 20 ± 5%, respectively.

+he retinal images were acquired using three different digital fundus cameras, TOPCON 3D OCT-2000, Kowa VX-10𝛼, and TOPCON TRC-NW300, all of them centered either on the macula or optic disc. These images are collected from subjects visiting an eye clinic due to a concern for their eye health.
 
-#### Who are the source data producers?
+- *Pretreatment of Samples*: Before image acquisition, pupils of most of the subjects were dilated with one drop of tropicamide at 0.5% concentration. The fundus images were captured with position and orientation of the patient sitting upright with 39 mm (Kowa VX–10) and 40.7 mm (TOPCON 3D OCT-2000 and TOPCON TRC-NW300) distance between lenses and examined eye using non-invasive fundus camera.
+- *Fundus Camera Specifications*: Regular retinal fundus images were acquired using three different digital fundus cameras. Details of camera model, hardware used, field of view (FOV), resolution, and number of images included in the dataset are given in Table 2.
+- *Data Quality*: The dataset is formed by extracting 3200 images from the thousands of examinations done during the period 2009–2020. Both high-quality and low-quality images are selected to make the dataset challenging.

+Initially, all the images were labeled by two ophthalmologists independently. 
+The reference standard for presence of different diseases was assigned based on the comprehensive evaluation of the subjects clinical records and visual fields.
+If a fundus image shows presence of more than one disease, then multiple labels are assigned to the single image. 
+After the ophthalmologists completed initial labeling of fundus photographs, the leader of the project team checked and confirmed or corrected through consultation from both the ophthalmologists when difference in diagnostic assessments was observed to get adjudicated consensus for the labels.
