Abstract

The optic disc and the macular are two major anatomical structures in the human eye. Optic discs are associated with the optic nerve. Macular mainly involves degeneration and impaired function of the macular region. Reliable optic disc and macular segmentation are necessary for the automated screening of retinal diseases.A swept-source OCTA system was designed to capture OCTA images of human eyes. To address these segmentation tasks, firstly, we constructed a new Optic Disc and Macula in fundus Image with Optical Coherence Tomography Angiography (OCTA) dataset (ODMI). Secondly, we proposed a Coarse and Fine Attention-Based Network (CFANet).The five metrics of our methods on ODMI are 98.91%, 98.47%, 89.77%, 98.49%, and 89.77%, respectively.Experimental results show that our CFANet has achieved good performance on segmentation for the optic disc and macula in OCTA.
