15 What about phacoclastic inflammaton? Phacoclastic uveitis is a term used to characterize the inflammation seen around a ruptured lens as is seen in these cases. The term carries with it the implication that the inflammation is caused by the release of lens proteins otherwise sequestered. I believe that in these dogs the inflammation is do to bacterial infection and not simply exposure of lens proteins.
