Posner-Schlossman症候群の臨床像—1．隅角結節

Clinical features of Posner-Schlossman syndrome: 1. Nodules in the anterior chamber angle

　隅角結節の認められたPosner-Schloss—man症候群の5例を報告した。隅角結節は白色あるいは灰白色で100〜200ミクロンと小さく，下方隅角の毛様体帯，強膜岬，線維柱帯およびシュワルベ線上に存在した。眼圧が下降してから出現することが多い。3例に隅角色素の変動を認めた。PS症候群では線維柱帯炎がおこっており，炎症産物が隅角を覆い隅角結節を形成すると推測された。さらに3例には隅角結節よりも小さい灰白色の虹彩結節も観察された。隅角周辺虹彩前癒着および瞳孔癒着はなかった。硝子体混濁はなく，検眼鏡的に眼底に異常はなかった。ぶどう膜炎と関連する全身疾患はまだみつかっていない。

We observed nodules in the anterior chamber angle in 5 cases with typical features of glaucomatocyclitic crisis. The nodules appeared as white or greyish oval mass of 100 to 200 microme-ters in diameter. They were more frequent along the inferior circumference of the angle, and were located on the ciliary band, scleral spur, trabecular meshwork and the ring of Schwalbe. The nodules became manifest after spontaneous or treatment -induced resolution of acute attacks and usually after normalization of intraocular pressure.

In 3 cases in the series, we noted increase in the amount of pigmentation in the chamber angle after the attack when compared with that during the attack. It appeared that inflammatory materials secondary to trabeculitis covered the trabecular meshwork and formed the nodules. We observed similar greyish nodules on the iris in 3 eyes in the series.

Presence of nodules in eyes with glaucomatocy-clitic crisis has not been reported, to out best knowledge, in past literature.
