Yes, and that’s an important point. In addition
to looking for meibomian gland atrophy (Figure 3) you
have to express the meibomian gland to identify MGD,
which epidemiological studies show will be present but
not obvious in some of your dry eye patients

“drop out” (atrophy) can be seen in the space

Disfunzione delle ghiandole di Meibomio
Associazioni meno comuni
ma importanti includono il trattamento dell’acne vulgaris
con isotetrinoina, che porta a un’atrofia reversibile delle
ghiandole di Meibomio, perdita della densità acinare alla
meibografia, ridotto volume e maggiore viscosità delle secrezioni(

Abstract

BACKGROUND:

Secretions from the meibomian gland are believed to be important in reducing ocular surface water evaporation and preventing dry eye. Patients with blepharitis frequently have meibomian gland dysfunction with loss of meibomian glands (drop out). The authors hypothesized that dry eye that often occurs in patients with chronic blepharitis is secondary to increased evaporation associated with gland loss.
