Transactions . on of the right eye, which hadbeen removed, was made by Dr. Standish McCleary, whofurnished me with the following report: A horizontal section through the equator of the eyeshows that more than half of the area normally filled by thevitreous is occupied by a mass measuring by lens is missing. The vitreous is more cellular thannormal and contains newly formed capillaries. 838 Friedenwald: Retinitis With Massive Exudation. The mass of tissue above mentioned is firmly attachedto or rather continuous with the retina at one point andlaterally is connected by a delicate reticulum of hyalinefibers. At the point of attachment the tissue is fullyorganized fibrous tissue, and is loaded with pigment whichcan be directly traced to the pigmented layer of the greater part of the mass is quite cellular and containsa great number of blood-vessels which are in immediatecontact with the cells (Fig. 10). A low-power view isstrongly suggestive of glioma or sarcoma. Careful study. Fig. 8.—Case 2. Visual Field, March 19, 1910. of the mass with higher magnification shows a great diversityboth in the character of the cells and the amount and natureof the intercellular substance in various fields (Fig. 11).Some individual fields present an exact picture of mixed-cellsarcoma, but adjoining them can be seen areas of lympho-cytes, plasma cells, fibroblasts and developing connective tis-sue in all stages from the faintest fibrillation to well-maturedtissue. Beautiful fibrin network, as well as masses of hyalineand canalized fibrin, are seen in the less cellular areas.
