Giant papillary conjunctivitis and meibomian gland dysfunction blepharitis.

In this prospective pilot study we saw 42 consecutive giant papillary conjunctivitis (GPC) patients (80 eyes), all of whom were found to have some meibomian gland dysfunction blepharitis. Severity of GPC at presentation correlated with severity of meibomian gland dysfunction blepharitis (Kendall's tau b averaged 0.246 across the adjusted statistical analyses). Thirty-two patients (63 eyes) were refit after treating meibomian gland dysfunction blepharitis. Twenty-eight of these patients (55 eyes; 87%) continue to wear contact lenses, maintaining an improvement in GPC (mean follow-up 21 months; range 11-36 months). We hypothesize that meibomian gland dysfunction blepharitis may play a role in the pathogenesis of GPC and suggest that a large, controlled, multi-observer study be performed to further investigate this possible association.
