An American text-book of genito-urinary diseases, syphilis and diseases of the skin . ear more hyperemic thanthe rest of the fundus. The arteries are reduced somewhat in size, or seemso by comparison with the enlarged veins. The latter are only partially con-cealed by the general edematous cloudiness, and in places appear clearlywithout a widened irregular reflex. They are often very tortuous. Thereare no vitreous opacities to prevent clear reflex of the retinal opacity. Retinitis Exudativa.—In addition to the symptoms indicated, thereare sometimes to be seen whitish radiating patches situated in the inner layersof the retina, usually following the course of the blood-vessels, extendingfrom the border of the papilla or situated near to the same, located withinthe inner layers of the retina, which exert a pressure upon the blood-vesselsso as to diminish their size and interfere with their course. This form, more-over, is sometimes accompanied by hemorrhages, but not always. (See caseof the writers, Fig. IV., Plate 14, in which such plastic exudation is shown Plate Fig. I.—Choroiditis disseminata, showing the early stage of this form of this disease, occurring in apatient with a distinct history of acquired syphilis five years ago. Scattered over the fundus were in-numerable whitish-yellow circular patches, which are seen in the figure to occupy not only the regionof the periphery, but also that of the macula. (Critchett and Juler.) Fig. II.—Later stage of disseminated choroiditis ; patches distributed over the fundus either towardthe periphery or near the central region. The recent ones have a yellowish-red appearance; when moreadvanced, a yellowish-white color; and still later become quite white and glistening, with little aggre-gations of pigment attached to their edges or in some part of their area. Fig. 2 is a typical case of thiskind: in the left eye both fundi were affected. (Juler.) Fig. III.—The condition usually shown in the fundus in syphilitic
