Among the most striking cells in diseases of the retina, especially where pseudogliomata are concerned, are the fatty granular cells, generally believed to be fat phagocytes. Coats (1908) believed they were degenerate leukocytes; Leber (1915) said they were derived from the pigment epithelium; Marshall and Michaelson (1933) believed them to be reticuloendothelial cells, and there have been other less likely suggestions. Each point of view has had its supporters.Despite the fact that pseudogliomata are fairly commonplace in India, there emerges from the case to be reported here several interesting features, although that dealing with the retinal pigment epithelium seems the most important; the present study supports Leber's view as to the origin of the fatty granular cells.
