A – Section 258 (masson trichrome, X10 magnification), with Border Tissue highlighted with white arrows. This histologic section was located immediately adjacent to the section shown in Figure 7. Note that the Border Tissue of Elschnig is seen as a connective tissue strut (stained blue) connecting the anterior sclera to Bruch’s membrane and enclosing the choroid. A more complete view of this section is shown in Figure 9.
B – The Border Tissue signal in the matched interpolated B-scan is highlighted using white arrows. SD-OCT appears to accurately capture the orientation of the Border Tissue with an internally oblique configuration seen nasally (left) and an externally oblique configuration seen temporally (right).28
