Diabetic Retinopathy (DR) is a serious eye disease caused by long-term diabetes and may lead to blindness if not detected early. Deep Learning (DL) and Convolutional Neural Network (CNN) models are widely used for automated DR detection from retinal fundus images. In this study, an enhanced activation function is proposed to improve CNN performance by reducing training loss and computational complexity while increasing accuracy. Multiple public datasets, including DIARETDB0, DRIVE, CHASE, and Kaggle DR datasets, were used for evaluation. Among the tested models, ResNet-152 achieved the highest accuracy of 99.41% on the Kaggle dataset. The results demonstrate the effectiveness of the proposed approach for accurate and reliable DR diagnosis.
KEYWORDS
The proposed deep learning–based diabetic retinopathy detection system provides an efficient and automated approach for retinal image classification. By integrating CLAHE preprocessing, data augmentation, CNN-based feature extraction, ResNet architecture, and ensemble learning, the system aims to achieve accurate and reliable diabetic retinopathy stage detection. The methodology enhances feature learning, improves classification robustness, and reduces prediction variability. Automated retinal screening can support ophthalmologists in early diagnosis, minimize manual workload, and enable large-scale clinical screening. Overall, the proposed framework demonstrates the potential of artificial intelligence and deep learning techniques in improving healthcare accessibility, diagnostic efficiency, and prevention of vision-related complications.
