Morphometrics in three dimensional choroidal vessel models constructed from swept-source optical coherence tomography images.

ABSTRACT: We created three types of vessel models: vessel volume, surface, and line models from swept-source optical coherence tomography images and tested experimentally calculated three-dimensional (3D) biomarkers. The choroidal volume (CVolume), surface area (VSurface), and vessel length-associated index (VLI) were measured. The calculated 3D parameters were the mean choroidal thickness, choroidal vascularity index (CVI), vessel length density index (VLDI), vessel length to the stromal (VL-S) ratio, surface-to-volume ratio (S-V ratio), and vessel diameter index (VDI). Cluster analysis showed that the parameters were classified into two clusters: one was represented by the VVolume including the CVolume, VSurface, CVI, S-V ratio, VLI, VDI, and subfoveal choroidal thickness and the other by the VL-S
