Visual Field, August 19, 1910. The question in this specimen is to decide between aneoplasm and an organizing inflammatory exudate. Whilethere are a few fields in which the structure of sarcoma orglioma is closely simulated, taken in its entirety, we seemto be dealing with a massive retinal exudate gradually be-coming changed into connective tissue. Another sectionmade in the same plane, but on a lower level than that justdescribed, shows chronic choroiditis. The choriocapillaris 840 Friedenwald: Retinitis With Massive Exudation. is almost obliterated, and is covered by several layers ofconnective tissue of varying density, in some of whichpigment is abundant and hyaline degeneration is seen. Asthis newly formed connective tissue is followed it becomesbroader, and beautiful areas of forming and mature osseoustissue are seen. The haversian canals, lacunae and lamellaeand osteoblasts are typical. This section is a typical pictureof ossifying choroiditis. It is not poss
