An experimental model of acute immune-complex uveitis.

We developed an experimental model of anterior uveitis by injecting ovalbumin or bovine serum albumin into the anterior chamber of sensitized rabbits. All the eyes showed leakage of serum proteins into the aqueous humor within 30 min. and developed uveitis within 24 hrs. which lasted at least a week. On histological examination, large numbers of polymorphonuclear (PMN) leucocytes and only occasional mononuclear cells were seen in the iris, the ciliary body and the irido-corneal angle. Immunohistological examination revealed 7s gamma globulin in the walls of blood vessels, in the interstitium and inside the PMN leucocytes. Contact radiographs of eyes challenged repeatedly showed extensive neovascularization of the iris and ciliary body.

Immunological studies of human anterior uveitis.

Immunofluorescent studies revealed extracellular deposits of IgG and C3 as well as immunoglobulin containing inflammatory cells in the affected iris of a patient suffering from endogenous acute uveitis. Antibodies to uveal components were detected in the serum of 4 out of a total of 23 endogenous uveitis patients examined. Examination of these 23 sera also revealed antinuclear activity in one, antismooth muscle activity in one, and anti-mitochondrial activity in three. None of the sera showed anti-thyroglobulin activity. Antibodies to uveal components or immune complexes containing 'auto-antibodies' do not appear to be a common source of tissue damage in human endogenous anterior uveitis.
