中心性漿液性脈絡網膜症にみられる黄斑部網膜色素上皮の顆粒状萎縮斑

Granular atrophic fleck of retinal pigment epithelium in central serous chorioretinopathy

　1．中心性漿液性脈絡網膜症での網膜色素上皮の顆粒状萎縮斑の初発螢光眼底血管造影所見は，境界不明瞭な組織染を示す網膜色素上皮の機能失調所見である。

　2．網膜色素上皮の顆粒状萎縮斑は経過中に拡大することがあることを確認した。

　3．網膜色素土皮の顆粒状萎縮斑の初発変化および顆粒状萎縮斑の拡大はともに，脈絡膜の循環障害によることが示唆された。

We observed two cases with central serous chor-ioretinopathy by means of fluorescein fundus angio-graphy. Both were males aged 39 and 50 years each. During the early phase in the angiogram, we detect-ed granular atrophic fleck in the macula. The fleck was located at the level of retinal pigment epith-elium and later turned into ill-defined patch due to tissue staining. The fleck increased in size during the course of the disease. Choroidal circulatory disorder seemed to underlie the observed atrophic fleck and its enlargement.
