The important complications of staphylococcic blepharitis (the second most common type of marginal blepharitis) include chronic conjunctivitis, hordeola, meibomitis, trichiasis, marginal infiltrates and ulcers, infectious eczematoid dermatitis, mercury and silver staining, epithelial keratitis and, rarely, a nontuberculous type of phlyctenulosis with pannus. The disease is not self-limited and successful treatment is difficult in old, complicated cases. Early treatment of the disease, which often starts in childhood, is of first importance. The use of corticosteroids to suppress inflammation carries a real danger of encouraging Candida superinfection. © 1969.
