All are complications of ulcerative blepharitis, EXCEPT:

Blepharitis is a chronic inflammation of lid margin. Some of the complications of ulcerative blepharitis are madarosis, trichiasis, ectropion, epiphora, tylosis and milphosis. Madarosis is said to occur when eyelashes fall out of place and and are either replaced or not replaced by few and scattered eyelashes. Trichiasis refers to misdirected and distoed cilia rubbing against the cornea. Tylosis refers to hyperophy of lid margin. Milphosis refers to permanent reddening of the lid margin.
