Abstract Retinal disorders represent a growing global health crisis, particularly among the working-age population. While manual screening of fundus imagery is the standard, it remains a labour-intensive process dependent on specialized expertise. This study addresses the urgent demand for rapid, automated diagnostic tools by evaluating the efficacy of lightweight Deep learning (DL) architectures for multi-class retinal disease identification.
Utilizing a public dataset of 4,217 images, the study performed a comparative analysis of four Convolutional Neural Network (CNN) architectures: MobileNetV2, VGG16, DenseNet121, and EfficientNetB0. Each model was assigned with classifying images into four categories: Normal, Diabetic Retinopathy, Glaucoma, and Cataract. Experimental results identify MobileNetV2 as the superior model, achieving a peak accuracy of 94.08%, an F1-score of 0.9430, and a mean Average Precision (mAP) of 0.9786.
With a calculated efficiency score of 0.4157, MobileNetV2 demonstrates the ideal balance between high diagnostic precision and low computational demand. These findings highlight that streamlined CNNs are uniquely suited for real-time deployment in resource-constrained environments. Ultimately, this research provides a robust foundation for AI-assisted ophthalmic screening, facilitating earlier clinical intervention and improved patient outcomes globally.
