摘要
From OCT-measured data, only the image data of the choroidal vascular network present in the layer of the choroidal layer is selectively extracted, thereby accurately obtaining the thickness of the choroidal vessels and thickness of the choroidal vascular network from the image data, to allow for quantitative evaluation of the choroidal vascular network. The optical coherence tomography apparatus has an optical coherence tomography device, and a computer that processes the three-dimensional OCT tomographic images obtained based on the OCT-measured data acquired by the optical coherence tomography device. The computer functions as a means for selectively separating out only the images of the choroidal vessels from the three-dimensional OCT tomographic images to acquire image data of the choroidal vessels, and also as a means for obtaining the data to be used in the quantitative evaluation of the shape of the choroidal vessels based on the image data of the choroidal vessels.
