(A) Anterior uveitis typically seen in noneffusive cases of FIP. Mild iridal neovascularization (rubeosis iridis) and hyphema are evident in the anterior chamber of the right eye (OD). (B) Fibrin formation, hypopyon, and evidence of mild diapedesis are suggestive of blood–ocular barrier breakdown associated with mild anterior uveitis. (C) Severe iritis, with rubeosis iridis, aqueous flare, hypopyon, and keratitic precipitates. These precipitates, known as “mutton-fat” precipitates, are suggestive of a chronic granulomatous disease process.
