Previous studies in our laboratory have demonstrated pollen-specific IgG antibodies in the tears of patients with vernal conjunctivitis (VC) and elevated tear IgG levels in patients with contact lens-induced giant papillary conjunctivitis (GPC). Tear secretions were examined for complement (C) proteins to determine the role of this effector system in the pathogenesis of these ocular disorders. The tears of VC (15) and GPC (10) patients with active disease had elevated tear levels of both C3 and factor B. By use of transferrin as a marker for the leakage of plasma proteins into the tears, most C3 was locally produced by the conjunctival tissues. Although immune complexes could not be detected in the tear secretions, increased levels of C3 des Arg were present in the tears that suggested complement activation with the generation of anaphylatoxins. These studies suggest that complement may be important in the inflammatory ocular process of VC and GPC and that the generation of anaphylatoxins (C3a), even by nonimmune mechanisms, may contribute to basophil and mast cell activation with the release of inflammatory mediators into the tear secretions.
