並列摘要

Three cases of senile type and one case of juvenile type of hemorrhagic disciform degeneration of the macula are presented here with the detailed descriptions of their clinical, fundoscopic, slitlamp, and fluorescein angiographic findings. These findings along with the possible pathology and the pathogenesis of the disease are analysed and discussed.
Evidences suggest that the extravasation of blood or serum beneath the pigment epithelium in senile hemorrhagic disciform degeneration of the macula is due to degenerative changes in the choriocapillaries, Bruch's membrane and drusen deposits on Bruch's membrane. The neovascular invasion of the subpigment epithelial space from the choriocapillaris represent complications of senile macular choroidal degeneration, which predispose the eye to the development of serous and hemorrhagic disciform degeneration of the macula.
As to the pathogenesis of the juvenile hemorrhagic disciform degeneration of the macula some other unknown causes may be attributed. Focal choroiditis is probably reponsible for the disease, but further study is required for its solution.
