諸種眼疾患における視神経乳頭の螢光造影所見の解析—第1報乳頭の発赤，腫脹をきたす疾患について

Angiographic Differences of Optic Disc in Various Diseases.:Report 1. Optic Disc with Redness and Swelling

緒言

　視神経乳頭は視神経疾患のみならず，疾患の二次的影響により検眼鏡的に，ある時は発赤，腫脹をあらわし，またある場合には褪色，萎縮の変化を生じ，原疾患特有の形態を示すが，これら種々の変化は乳頭部血管系の循環状態を反映する所見と考えられる。

　したがつて，病変に相当する乳頭の特定の変化を，螢光眼底像の面からとらえようとする試みは，視神経疾患に関しては早くから行なわれてきた。

Fluorescein angiography was made in patho-logical optic disc with redness and swelling, involving : choked disc (6 eyes), papillitis (7 eyes), idiopathic uveitis (9 eyes) and nephritic retinopathy (1 eye). Photography of the an-giographic sequence was conducted at the rate of 3 frames per second.

Angiographic features of choked disc were characterized by rapid extravasation of dye from prelaminar capillaries and, to a lesser degree, from engorged radial peripapillary ca-pillaries. The extent of resultant dye staining in late venous phase coincided with the distri-bution of capillary microaneurysms.
