偽落屑症候群の隅角所見と緑内障病型

Types of glaucoma as related to gonioscopic features in pseudoexfoliation syndrome

（B2-2-31）　偽落屑症候群213例293眼の隅角所見と緑内障病型を検討した。広隅角237眼（80.9％），狭隅角22眼（7.5％），合わせて開放隅角259眼（88.4％），閉塞隅角34眼（11.6％）であった。開放隅角緑内障は111眼（37.9％）に，閉塞隅角緑内障は34眼（11.6％）にみられた。閉塞隅角緑内障のうち混合型緑内障が13眼（38.2％）にみられた。偽落屑症候群の緑内障は，水晶体嚢性緑内障としての開放隅角緑内障だけでなく閉塞隅角緑内障もみられ，そのうちの1／3は混合型緑内障であることが明らかとなった。

We reviewed 293 eyes in 213 cases of pseudoexfoliation syndrome regarding the gonioscopic features and types of glaucoma. The chamber angle was closed in 34 eyes (11.6%) and open in 259 eyes (88.4%) of which the chamber angle was wide in 237 eyes (80.9%) and narrow in 22 eyes (7.5%) . Open-angle glaucoma was present in 111 eyes (37.9%) and closed-angle glaucoma in 34 eyes (11.6% ) . The latter included 13 eyes of combined-mechanism glaucoma. The findings show that pseudoexfoliation glaucoma consists of both open-angle and closed-angle glaucoma including combined-mechanism glaucoma in about one-third in the latter.
