    apoplexy may also occur without inflamma- tion, from injury or atheroma of vessels]. In retinitis of Bright's disease {retinitis albumi- nuric a or nephritica) there is large amount of exudation, which soon becomes fatty, in region of papilla, and also numbers of white, glisten- ing, stelliform spots scattered about; and he- morrhages are numerous. In retinitis, in course of syphilis, there may be numerous white, punctiform opacities, especially in re- gion of macula, and hemorrhages are not likely to occur. In retinitis of leucocythsemia {retini- tis leuccemica) there are round, yellowish- white patches, sometimes with red borders, strewn about periphery of retina, and near macula—formed from masses of exuded white and red blood-corpuscles ; fundus has pale yellow tint, and arteries look pale and blood- less. Suppuration of retina scarcely ever occurs except in panophthalmitis. Ophthalmoscopic appearances of retinitis are: Opacity of retina, varying in degree from that of fine mist or film to that of dense, white patch of exudation. Vessels are obscured the more the opacity lies in inner layers. Disc looks blurred, especially its edges. Arte- ries usually of normal calibre, but veins dis- tended and tortuous. Blood-extravasations appear as irregular, red patches ; if in inner layers, among nerve-fibres, they are striated, and have feathery edges ; if in outer layers, they appear more smooth and uniform.
