Semiautomated Segmentation of the Choroid in Spectral-Domain Optical Coherence Tomography Volume Scans

Abstract

Excellent agreement was observed between the algorithm and manual choroidal segmentation in both normal eyes and those with non-neovascular AMD. The choroid was thinner in AMD eyes. Semiautomated choroidal thickness calculation may be useful for large-scale quantitative studies of the choroid.
