Example of a linear artifact line (small linear segment) below, at the same level as or above the sclerochoroidal interface (bidirectional arrow) in EDI-OCT images. (A) A female chronic primary angle closure glaucoma patient with a linear artifact line below the sclerochoroidal interface with a SFCT of 429 μm. (B) A control male subject in which the linear artifact was at the same level as the sclerochoroidal interface with a SFCT value of 485 μm. (C) A central serous chorioretinopathy patient with a linear artifact line above the sclerochoroidal interface with a SFCT of 573 μm. SFCT: subfoveal choroidal thickness.
