Early and timely detection of this problem is critical for a good prognosis. An automated system for this purpose contains several phases like identification and classification of lesions in fundus images. Machine learning techniques based on manual extraction of features and automatic extraction of features with convolution neural network have been presented for diabetic retinopathy detection. The recent developments like capsule networks in deep learning and their significant success over traditional machine learning methods for a variety of applications inspired the researchers to apply them for diabetic retinopathy diagnosis. In this paper, a reformed capsule network is developed for the detection and classification of diabetic retinopathy. Using the convolution and primary capsule layer, the features are extracted from the fundus images and then using the class capsule layer and softmax layer the probability that the image belongs to a specific class is estimated. The efficiency of the proposed reformed network is validated concerning four performance measures by considering the Messidor dataset. The constructed capsule network attains an accuracy of 97.98%, 97.65%, 97.65%, and 98.64% on the healthy retina, stage 1, stage 2, and stage 3 fundus images.<\/jats:p>","DOI":"10.1007\/s40747-021-00318-9","type":"journal-article","created":{"date-parts":[[2021,3,17]],"date-time":"2021-03-17T17:03:18Z","timestamp":1616000598000},"page":"2651-2664","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":258,"title":["Diabetic retinopathy detection and classification using capsule networks"],"prefix":"10.1007","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8544-6930","authenticated-orcid":false,"given":"G.","family":"Kalyani","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3134-0545","authenticated-orcid":false,"given":"B.","family":"Janakiramaiah","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2245-1278","authenticated-orcid":false,"given":"A.","family":"Karuna","sequence":"additional","affiliation":[]},{"given":"L.
