Meibomian gland dropout is best described as

Explanation:
Meibomian gland dropout represents loss of gland tissue due to acinar atrophy. The meibomian glands are the lipid-secreting units of the eyelids; with chronic obstruction and inflammation, the acini atrophy and disappear, which is why dropout appears on imaging as missing glands. Saying acinar atrophy with meibomian gland dropout precisely describes both the underlying tissue loss and the imaging finding. Gland hyperplasia would mean more glands, ductal dilation implies widening of ducts without tissue loss, and increased lipid secretion doesn’t reflect the loss of glands seen in dropout.
