Abstract:

Quality assessment of ultra-wide optical coherence tomography angiography (UW-OCTA) images followed by lesion segmentation and proliferatived diabetic retinopathy (PDR) detection is of great significance for the diagnosis of diabetic retinopathy. However, due to the complexity of UW-OCTA images, it is challenging to achieve automatic image quality assessment and PDR detection in a limited dataset. This work presented a fully automated convolutional neural network-based method for image quality assessment and retinopathy grading. In the first stage, the dataset was augmented to eliminate the category imbalance problem. In the second stage, the EfficientNet-B2 network, pre-trained on ImageNet, was used for quality assessment and lesion grading of UW-OCTA images. We evaluated our method on the DRAC2022 dataset. A quadratic weighted kappa score of 0.7704 was obtained on the task 2 image quality assessment test set and 0.8029 on the task 3 retinopathy grading test set. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
