  People with diabetes are more likely to develop diabetic retinopathy (DR)
than healthy people. However, DR is the leading cause of blindness. At present,
the diagnosis of diabetic retinopathy mainly relies on the experienced
clinician to recognize the fine features in color fundus images. This is a
time-consuming task. Therefore, in this paper, to promote the development of
UW-OCTA DR automatic detection, we propose a novel semi-supervised semantic
segmentation method for UW-OCTA DR image grade assessment. This method, first,
uses the MAE algorithm to perform semi-supervised pre-training on the UW-OCTA
DR grade assessment dataset to mine the supervised information in the UW-OCTA
images, thereby alleviating the need for labeled data. Secondly, to more fully
mine the lesion features of each region in the UW-OCTA image, this paper
constructs a cross-algorithm ensemble DR tissue segmentation algorithm by
deploying three algorithms with different visual feature processing strategies.
The algorithm contains three sub-algorithms, namely pre-trained MAE, ConvNeXt,
and SegFormer. Based on the initials of these three sub-algorithms, the
algorithm can be named MCS-DRNet. Finally, we use the MCS-DRNet algorithm as an
inspector to check and revise the results of the preliminary evaluation of the
DR grade evaluation algorithm. The experimental results show that the mean dice
similarity coefficient of MCS-DRNet v1 and v2 are 0.5161 and 0.5544,
respectively. The quadratic weighted kappa of the DR grading evaluation is
0.7559. Our code will be released soon.
