Answer

Posterior blepharitis is principally related to dysfunction of the meibomian glands. Alterations in secretory metabolism and function lead to disease. The meibomian secretions become more waxlike and begin to block the gland orifices. The stagnant material becomes a growth medium for bacteria and can seep into the deeper eyelid tissue layers, causing inflammation. These processes lead to gland plugging, inspissated lipid secretory material, inflamed orifices, and formation of hordeola and chalazia.

Various corneal changes can also result from posterior blepharitis.
