Fundus exudation, as one of the main characteristics of eye diseases, is closely related to various eye diseases. However, due to its low contrast and blurred boundaries in medical images, retinal exudation is easily overlooked or confused. This paper proposes an improved U-shaped network model for segmentation of diabetic retinal exudation. This model adopts deep residual convolution in the encoding and decoding stages, which can effectively extract deep seepage features, solve overfitting and feature interference problems, and improve the model's feature expression ability and lightweight performance. In addition, by introducing an improved context extraction module, the model can capture a wider range of feature information, enhance the perception ability of retinal lesions, and perform excellently in capturing small details and blurred edges. Finally, the introduction of Convolutional Triple Attention Mechanism allows the model to automatically learn feature weights, focus on important features, and extract useful information from multiple scales. This method improves the efficiency of computer-aided detection and segmentation of retinal exudates. It not only helps doctors overcome the subjectivity of diagnosis to a certain extent through quantitative indicators, but also provides useful reference and inspiration for the auxiliary diagnosis of other similar diseases, which has important research significance.
