Abstract
With the increase of patients with retinopathy, retinopathy recognition has become a research hotspot. In this article, we describe the etiology and symptoms of three kinds of retinal diseases, including drusen(DRUSEN), choroidal neovascularization(CNV) and diabetic macular edema(DME). In addition, we also propose a hybrid attention mechanism to classify and recognize different types of retinopathy images. In particular, the hybrid attention mechanism proposed in this paper includes parallel spatial attention mechanism and channel attention mechanism. It can extract the key features in the channel dimension and spatial dimension of retinopathy images, and reduce the negative impact of background information on classification results. The experimental results show that the hybrid attention mechanism proposed in this paper can better assist the network to focus on extracting thr fetures of the retinopathy area and enhance the adaptability to the differences of different data sets. Finally, the hybrid attention mechanism achieved 96.5% and 99.76% classification accuracy on two public OCT data sets of retinopathy, respectively.
Highlights
Diabetic retinopathy (DR) is a common blinding disease, mostly in diabetic patients [1]
It can be seen from the table that the F1 values obtained by ResNet50, Res2Net50, SENet and SKNet on age-related macular degeneration (AMD) and NORMAL are significantly better than their F1 values obtained on Diabetic macular edema (DME), which indicates that generalization ability of the above models has certain defects, and hybrid attention proposed in this article effectively alleviates this problem
According to the distribution of lesion features in retinopathy images, we propose a hybrid attention mechanism to help the network lock foreground information in the image more accurately
Summary
Diabetic retinopathy (DR) is a common blinding disease, mostly in diabetic patients [1]. Changes in blood components of diabetic patients cause dysfunction of vascular endothelial cells, which leads to impaired retinal barrier in diabetic patients. Periodic examinations of diabetic patients and effective control of retinal diseases can prevent patients from transient or permanent blindness [2]. Diabetic macular edema (DME) is one of the main symptoms of diabetic retinopathy (DR) [3]. The main reason for this disease is the long-term hyperglycemia state of diabetic patients, which leads to increased vascular permeability of the retina and choroid of the eye, and the water molecules and some protein components in the blood can permeate through the damaged vascular walls and form edema in the macular area
