Globally, glaucoma is a leading cause of visual impairment and vision loss, emphasizing the critical need for early diagnosis and intervention. This research explores the application of deep learning for automated glaucoma diagnosis using retinal fundus photographs. We introduce a novel cross-sectional optic nerve head (ONH) feature derived from optical coherence tomography (OCT) images to enhance existing diagnostic procedures. Our approach leverages deep learning to automatically detect key optic disc characteristics, eliminating the need for manual feature engineering. The deep learning classifier then categorizes images as normal or abnormal, streamlining the diagnostic process. Deep learning techniques have proven effective in classifying and segmenting retinal fundus images, enabling the analysis of a growing number of images. This study introduces a novel mixed loss function that combines the strengths of focal loss and correntropy loss to handle complex biomedical data with class imbalance and outliers, particularly in OCT images. We further refine a multi-task deep learning model that capitalizes on similarities across major eye-fundus activities and metrics for glaucoma detection. The model is rigorously evaluated on a real-world ophthalmic dataset, achieving impressive accuracy, specificity, and sensitivity of 100%, 99.8%, and 99.2%, respectively, surpassing state-of-the-art methods. These promising results underscore the potential of our deep learning algorithm for automated glaucoma diagnosis, with significant implications for clinical applications. By simultaneously addressing segmentation and classification challenges, our approach demonstrates its effectiveness in accurately identifying ocular diseases, paving the way for improved glaucoma diagnosis and early intervention.
在全球范围内,青光眼是导致视力损害和视力丧失的主要原因,这凸显了早期诊断和干预的迫切需求。本研究探索了深度学习在利用视网膜眼底照片进行青光眼自动诊断中的应用。我们引入了一种从光学相干断层扫描(OCT)图像中提取的新型横断面视神经乳头(ONH)特征,以增强现有的诊断程序。我们的方法利用深度学习自动检测关键视盘特征,无需手动进行特征工程。然后,深度学习分类器将图像分类为正常或异常,简化了诊断过程。深度学习技术已被证明在对视网膜眼底图像进行分类和分割方面是有效的,能够分析越来越多的图像。本研究引入了一种新型混合损失函数,该函数结合了焦点损失和核熵损失的优势,以处理具有类别不平衡和异常值的复杂生物医学数据,特别是在OCT图像中。我们进一步优化了一个多任务深度学习模型,该模型利用主要眼底活动和青光眼检测指标之间的相似性。该模型在一个真实世界的眼科数据集上进行了严格评估,分别实现了令人印象深刻的100%、99.8%和99.2%的准确率、特异性和敏感性,超过了现有最先进的方法。这些有前景的结果强调了我们的深度学习算法在青光眼自动诊断方面的潜力,对临床应用具有重要意义。通过同时解决分割和分类挑战,我们的方法证明了其在准确识别眼部疾病方面的有效性,为改进青光眼诊断和早期干预铺平了道路。
