Thus I have seen cases of syphilitic choroiditis in which a largebluish-gray exudation has occupied the region of the yellow spot, and aroundthis were scattered to a considerable distance numerous smaller exudationsand atrophic patches, the periphery of the fundus being almost free fromany exudations. These appearances (more especially the gray, nebulouseffusion) at the yellow spot were almost identical in both eyes. [In syphilitic choroiditis there is said to be a peculiar dust-like punctateopacity of the vitreous, which at first is movable, but later the particlesbecome aggregated into masses of irregular shape and sometimes havingthread-like processes. These opacities are sometimes so dense as to com- [Fig. Atrophy after syphilitic choroiditis, showing various degrees of wasting, a. Atrophy ofpigment epithelium, h.

It is usually a late manifestation of syphilis, though it mayaccompany an early iritis, and it often affects only one eye. It is probablethat this is merely one stage of the chorio-retinitis disseminata with markedchanges in the choroid. (See Arch. f.
