Fluorescein Studies in Frecked Retina Syndrome

I．緒言

　一般にflecked retina syndromeとして扱われるものは，種々の大きさの黄色〜黄白色〜白色のdruse様depositが眼球の後極域に限局的に，あるいは広くみられるものである。1） Hu—tchinson-Tay choroiditis, 2）　macular degen—eration　（Holthouse-Batten），　3）　Doyne's honey—combed degeneration, 4）　Malattia Levan—tinese, 5）　fundus flavirnaculatus, 6）　fundusalbipunctatus, 7）　speckled multicolored fun—dus　（Bischler），　8）　fleck-retina　（Kandori）が挙げられている。

　上記のうち，Tay choroiditis, Holthouse-Ba—tten type, Doyne type, Malattia Levantineseは組織学的にもBruch膜のhyaline変性として示されているし遭遇することはきわめてまれである。

Fluorescein fundus photography was conduct-ed in cases with flecked retina syndrome. One case of fundus albipunctatus and 9 cases of colloid bodies, or drusen, were studied.

1. White spots in fundus albipunctatus in a 24-year-old male did not change in size and shape before and after injection of fluorescein. No abnormal finding was observed as concerns background fluorescein.

2. Two types could be distinguished as re-gards drusen or colloid bodies of the fundus. In some instances the size of the spots remained stationary throughout the various phases of fluorescence fundus photography.
