Time-domain versus SD-OCT in the generation of mirror artifacts. (A) Cirrus HD OCT five-line raster protocol with SD detection was used to acquire this scan from a patient with high myopia. The retina appeared tilted due to the long axial length of the eye. Mirror artifacts were observed in this scan (arrows). Individual retinal layers were better delineated with SD-OCT than with time-domain OCT. (B) StratusOCT with time-domain detection was used to acquire this scan from the same patient, by means of the macular thickness protocol. Although part of the retina crossed the 0-delay line (top right), no mirror artifact was observed.
