The growing amount of data leads us to propose an automated support system for medical staff. The key part of the system is a classification algorithm developed with modern machine learning techniques. The main contribution is to present a new approach for the classification of eye diseases using the convolutional neural network model. The research concerns the classification of patients on the basis of OCT B-scans into one of four categories: Diabetic Macular Edema (DME), Choroidal Neovascularization (CNV), Drusen, and Normal. Those categories are available in a publicly available dataset of above 84,000 images utilized for the research. After several tested architectures, our 5-layer neural network gives us a promising result. We compared them to the other available solutions which proves the high quality of our algorithm. Equally important for the application of the algorithm is the computational time, which is reduced by the limited size of the model. In addition, the article presents a detailed method of image data augmentation and its impact on the classification results. The results of the experiments were also presented for several derived models of convolutional network architectures that were tested during the research. Improving processes in medical treatment is important. The algorithm cannot replace a doctor but, for example, can be a valuable tool for speeding up the process of diagnosis during screening tests.<\/jats:p>","DOI":"10.3390\/s22134675","type":"journal-article","created":{"date-parts":[[2022,6,22]],"date-time":"2022-06-22T04:12:01Z","timestamp":1655871121000},"page":"4675","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Fast and Efficient Method for Optical Coherence Tomography Images Classification Using Deep Learning Approach"],"prefix":"10.3390","volume":"22","author":[{"given":"Rouhollah Kian","family":"Ara","sequence":"first","affiliation":[{"name":"Institute of Telecommunications, AGH University of Science and Technology, 30-059 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1629-1821","authenticated-orcid":false,"given":"Andrzej","family":"Matiola\u0144ski","sequence":"additional","affiliation":[{"name":"Institute of Telecommunications, AGH University of Science and Technology, 30-059 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrzej","family":"Dziech","sequence":"additional","affiliation":[{"name":"Institute of Telecommunications, AGH University of Science and Technology, 30-059 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Remigiusz","family":"Baran","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering, Automatic Control and Computer Science, Kielce University of Technology, 25-314 Kielce, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pawe\u0142","family":"Domin","sequence":"additional","affiliation":[{"name":"Consultronix S.A., 32-083 Balice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5578-416X","authenticated-orcid":false,"given":"Adam","family":"Wieczorkiewicz","sequence":"additional","affiliation":[{"name":"Consultronix S.A., 32-083 Balice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1264","DOI":"10.1016\/j.ophtha.2018.01.034","article-title":"Grader Variability and the Importance of Reference Standards for Evaluating Machine Learning Models for Diabetic Retinopathy","volume":"125","author":"Krause","year":"2018","journal-title":"Ophthalmology"},{"key":"ref_2","unstructured":"Edison Artificial Intelligence Analytics (2022, May 01).
