Ocular diseases such as Cataract, Age-Related Macular Degeneration, Diabetic Retinopathy, and uncorrected refractive errors like Myopia, constitute the leading causes of visual impairment globally, predominantly affecting the elderly populations. Early diagnosis is crucial to avert irreversible vision loss. Conventional diagnostic techniques like fundus fluorescein angiography (FFA), optical coherence tomography (OCT), and fundus image analysis can be resource-intensive and reliant on the expertise of specialists. In recent times, different automated methods for diagnosis have been developed to help specialists in their work. This study presents a comparative analysis of three deep learning models: EfficientNetB3 (CNN), ViT-B-16 (Vision-Transformer), and ConvNeXtXLarge (CNN inspired by Transformers), for multiclass ocular disease classification utilizing the ODIR-5K dataset. Among the three evaluated architectures, ConvNeXtXLarge demonstrated the highest performance, achieving an area under the receiver operating characteristic curve (AUROC) of 0.892 and EfficientNetB3 achieved an AUROC of 0.870, and ViT-B-16 achieved an AUROC of 0.864. Regarding classification accuracy, ConvNeXt-XLarge reached 73.6%, exceeding EfficientNetB3 by 4.0% and outperforming ViT-B-16 by 2.0%. Grad-CAM visualizations provided additional insight since the heatmaps generated by EfficientNetB3 appeared to align more closely with clinically relevant regions than those produced by ConvNeXtXLarge or ViT-B-16. This suggests that, while ConvNeXtXLarge and ViT-B-16 show better scores, EfficientNet gives a better clinically aligned decision. Architectural design plays a pivotal role in shaping both diagnostic accuracy and the transparency of models in ophthalmic imaging, as demonstrated by this comprehensive evaluation that combines quantitative metrics with interpretability insights.
