[Inflammation of the uvea--the cellular immune response in the iris (author's transl)]
Ultrastructural analyses of iris biopsies in 17 cases of uveitis with different etiology revealed that all cells involved in immunological reactions are present. Many plasmacells and lymphocytes, but also macrophages and mastcells are found. Destruction of cells and even necrosis as well as damage of blood vessels are run. No specific germs could be demonstrated and etiology was not further elucidated. But there remains no doubt on the immunological nature of uveitis.
