This paper presents a methodology for glaucoma detection based on measuring displacements of blood vessels within the optic disc (vascular bundle) in human retinal images. The method consists of segmenting the region of the vascular bundle in an optic disc to set a reference point in the temporal side of the cup, determining the position of the centroids of the superior, inferior, and nasal vascular bundle segmented zones located within the segmented region, and calculating the displacement from normal position using the chessboard distance metric. The method was successful in 62 images out of 67, achieving 93.02% sensitivity, 91.66% specificity, and 91.34% global accuracy in pre-diagnosis.
本文提出了一种基于测量人视网膜图像中视盘（血管束）内血管位移的青光眼检测方法。该方法包括分割视盘的血管束区域，在杯的颞侧设置参考点，确定位于分割区域内的上、下和鼻血管束分段区域的质心位置，并使用棋盘距离度量计算从正常位置的位移。该方法在 67 张图像中的 62 张成功，在预诊断中达到了 93.02%的灵敏度、91.66%的特异性和 91.34%的整体准确性。
