Retinitis Proliferans.—Manz described under this name an affection in whichdense masses of connective tissue extend out from the retina into the vitreous andcover a portion of the fundus—in fact, even the papilla itself (Pig. 256). Into thesemasses run new-formed vessels from the retina. For a number of these cases it is probablethat these masses of connective tissue have been preceded by haemorrhages, whichwere poured out from the retina into the vitreous and afterward became organized (seepage 571). (Much the most common cause of these are the spontaneous haemorrhagesoccurring in the retina and vitreous in young persons particularly as a result of tuber-culosis (see pages 562 and 573). Other causes alleged are anaemia, chlorosis, menstrualcongestion, syphilis, nephritis, diabetes, arteriosclerosis, oxaluria, etc. Other cases are

In the vitreous ofthe left eye close to the papilla lies a shining white mass having a structure partly fibrous, partly gran-ular. From this mass pass strands in different directions, some extending as far as the periphery ofthe fundus. No vessels are recognizable in the white mass, which rovers the upper half of the papilla.The other half of the papilla and the rest of the fundus are somewhat hazy Cowing to the presence of afaint opacity of the vitreous), and besides appear indistinct, because the ophthalmoscope i- adjustednot for them, but for the connective-tissue mass, which i.^ situated farther forward.
