Retinitis Leuchaemica.—In this, superadded to the general symptoms of inflam-mation of the retina (namely, retinal cloudiness and haemorrhages), there is found, asa characteristic feature, a light hue of the blood in the retinal vessels, which ordina-rily are greatly dilated. Furthermore, since in leuchaemia the blood that flows in thechorioidal vessels is of lighter color than normal, the entire fundus, even where thereis no retinitis present, is of a much lighter red than usual, and shows a yellowish Fig. 254.—Hemorrhagic Retinitis in a Woman of Forty-eight, who suffered from ChronicNephritis and Cardiac Hypertrophy. The outlines of the grayish-red papilla are obscured, the arteries of the retina are somewhatcontracted, and in places are concealed by the cloudiness of the retina. The veins are very tortuous,and from the character of their reflex streaks it can be seen that not all their convolutions lie in thesame plane. The retina, as a whole, shows a faint striate opacity, and 3 filled with very numerous,partly striate and partly rounded haemorrhages. To the left and below, between the two branches ofa vein, is a white spot which has originated from a haemorrhage. Likewise characteristic of leuchaemic retinitis are white patches with a red rim (con-sisting of white corpuscles surrounded by red ones); but such patches are present inonly a few cases of retinitis leuchaemica.
