| 2 | Automatic segmentation of foveal avascular zone based on adaptive watershed algorithm in retinal optical coherence tomography angiography images显示文摘The size and shape of the foveal avascular zone(FAZ)have a strong positive correlation with several vision-threatening ret inovascular diseases.The identification,segmentation and analysis of FAZ are of great significance to clinical diagnosis and treatment.We presented an adaptive watershed algorithm to automatically extract F AZ from retinal optical coherence tomography angiography(OCTA)images.For the traditional watershed algorithm,'over-segmentation'is the most common problem.FAZ is often incorrectly divided into multiple regions by redundant'dams'.This paper analyzed the relationship between the'dams'length and the maximum inscribed circle radius of FAZ,and proposed an adaptive watershed algorithm to solve the problem of'over-segmentation'.Here,132 healthy retinal images and 50 diabetic retinopathy(DR)images were used to verify the accuracy and stability of the algorithm.Three ophthal-mologists were invited to make quan titative and qualitative evaluations on the segmentation results of this algorithm.The quantitative evaluation results show that the correlation coffi-cients between the automatic and manual segmentation results are 0.945(in healthy subjects)and 0.927(in DR patients),respectively.For qualitative evaluation,the percentages of'perfect segmentation'(score of 3)and'good segmentation'(score of 2)are 99.4%(in healthy subjects)and 98.7%(in DR patients),respectively.This work promotes the application of watershed algorithm in FAZ segmentation,making it a useful tool for analyzing and diagnosing eye diseases. | Jian Liu Shixin Yan Nan Lu Dongni Yang Chunhui Fan Hongyu Lv Shuanglian Wang in Zhu Yuqian Zhao Yi Wang Zhenhe Ma Yao Yu | 2022 | Journal of Innovative Optical Health Sciences2022，15，1： | 3 |
