TUBERCULOSIS OF THE IRIS.
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.
