On October 17, 1957, a 2-year old American Saddlebred gelding was admitted to the Stange Memorial Clinic. The only history given was "something wrong with the right eye". Examination showed a soft swelling in the area of the lower eyelid. A hard object could be palpated in this area. There was also considerable exudate present on the eye, but no break in the continuity of conjunctiva or skin.
