Abstract
Macular disease is one of the major causes of blindness. Optical coherence tomography (OCT) is a commonly used ophthalmic diagnostic technique to assist ophthalmologists in their analysis and treatment. However, manual analysis is a time-consuming, heavy and subjective process. In this paper, we propose an improved EfficientNet model for retinal OCT image classification, named TL-RA-EfficientNet. It introduces a Re-Attention module to enable the model to identify the lesions with small areas and fuzzy shapes. During training, a data augmentation strategy is introduced to solve the class-imbalance problem, and a transfer learning strategy is adopted to speed up the convergence of the model. The experimental results on the UCSD dataset show that the average recognition accuracy, sensitivity and specificity of our model are 99.9%, 99.9% and 99.97%, respectively, which are more effective than previous classification methods.
