Automated segmentation and extraction of posterior eye segment using OCT scans [PDF]
arXiv, 2021 This paper proposes an automated method for the segmentation and extraction of the posterior segment of the human eye, including the vitreous, retina, choroid, and sclera compartments, using multi-vendor optical coherence tomography (OCT) scans. The proposed method works in two phases.

Choroidalyzer: An open-source, end-to-end pipeline for choroidal analysis in optical coherence tomography [PDF]
arXiv, 2023 Purpose: To develop Choroidalyzer, an open-source, end-to-end pipeline for segmenting the choroid region, vessels, and fovea, and deriving choroidal thickness, area, and vascular index. Methods: We used 5,600 OCT B-scans (233 subjects, 6 systemic disease cohorts, 3 device types, 2 manufacturers).
