This has occurred as the result of inoculation of the aqueous humor in
the smaller animals, and as a spontaneous localization of the disease in
cattle (Hess, Röder, Fischöder, etc.). In Hess’s case, the left eye was
shrunken to half the size of the sound right eye, and small caseated
tubercles were present in both iris and choroid. There are usually
coincident tubercles in other organs, and these with the nodular
appearance of the iris swellings, if visible in life, may assist in
diagnosis. (See _Symptomatic Iritis_, and _Tuberculosis_.)
