Figure 9. The 3D meibomian gland of subject D (68 years old, female) with mild MGD (meiboscore grade 0 or 1).

A: Although the extent of the meibomian gland loss seemed minimal, we saw definite atrophic changes in the acini attached to the central ducts. The contours of the acini were ill-defined and the acini small; B: These findings are consistent with noncontact meibography showing ill-defined acini.
