Fig. 1.

Intrinsic age-related morphological parameters imaged by HD-OCD in en face (EF) and cross-sectional (CS) mode. a–c Young women: a small rhomboidal furrow pattern is noticed (magenta arrow). ET (red vertical lines) is >60 µm. DEJ is jagged on cross-sectional image (green arrow) and papillary rings are regular and small (green circle). DEJ is thickest in young adult (orange line). d–f Middle aged women: less intersecting furrows are noticed resulting in larger rhomboidal furrow pattern (yellow arrows). ET (red lines) is lesser compared to young adult. More flattening of the DEJ is observed on cross-sectional image (green arrow). Papillary rings are larger and more irregular on en face imaging (green circle). DEJ is thinner compared to young adult. g–i Older aged women: a disarranged furrow pattern is observed with some linearization of the furrows (dark green arrows). ET is thinnest in this group (red vertical lines). The DEJ is flat and very thin (green arrow). This results in almost absence of papillary rings on en face image
