This script is for quantification of retinal vessel tortuosity in fundus/OPTOS images. Several measures of tortuosity is calculated and saved in an excel file. Tortuosity measures are based on vessel centerline within a circumpapillary region centered on the optic nerve head (ONH). The user needs to select the center of ONH and its diameter. Also, the user can modify thresholds for vessel segmentation. Additionally, the user needs to select endpoints of each vessel for extracting the centerline and calculating its tortuosity.
Please see the user manual Retinal Vessel Tortuosity.pdf for further instruction.
