In conclusion, EDI-OCT imaging for SFCT measurement has recently emerged as a powerful adjunct to pathogenesis and prognosis and remains a research focus. However, a linear artifact is located stably at a depth of 485 μm beneath the retinal pigment epithelium in 81.88% of subjects which might confound the measurement of SFCT. Images must be assessed with care and awareness of the existence of linear artifacts when determining the sclerochoroidal interface, especially when it is approximately 485 μm.
