隅角血管

Gonio-vessels

緒　言

　前房隅角鏡検査で隅角新生血管を観察する機会は極めて多い。しかし，病的ではない隅角血管に関する報告はChatterjee^1），Henkind^2）のわずか2論文にすぎない。

　われわれは，隅角血管にとりわけ重大な関心を持つ緑内障外来で，隅角血管をしばしば観察し，その写真撮影ならびに螢光造影を試みたので報告する。

Out of 460 eyes which had wide anterior chamber angles 13 eyes were found to have normal gonio-vessels. Circular ciliary band vessel was found in 2 eyes, radial iris vessel in 2 eyes and radial ciliary band vessel in 10 eyes. Fluo-rescein anterior chamber angle angiography re-vealed no leakage of fluorescein from these go-nio-vessels.

Our findings indicate that the incidence of gonioscopically visible vessels in the chamber angle is decidedly less in Japanese eyes than in Caucasians and that such physiological vessels can be differentiated from newly formed ones by means of fluorescein angiography of the chamber angle.
