急性原発閉塞隅角症または急性原発閉塞隅角緑内障の両眼同時発症例と片眼発症例の比較

Comparison of unilateral and bilateral acute primary angle-closure

要約　目的：急性原発閉塞隅角症と同緑内障の両眼と片眼発症例の比較。対象と方法：過去25年余に当科を受診した急性閉塞隅角症と同緑内障の63例75眼を検索した。男性16眼，女性59眼で，年齢は44～85歳（平均67歳）であった。12例が両眼発症，51例が片眼発症であった。結果：両眼発症は男性5例（42％），片眼発症は男性6例（12％）であり，両眼発症には男女差がなく，片眼発症は女性が有意に多かった。発症年齢，屈折，眼軸長，中心前房深度，水晶体厚については，両眼群と片眼群とで有意差がなかった。結論：急性原発閉塞隅角症と同緑内障では，発作眼と非発作眼は同様な眼球構造を持ち，両眼発症が63例中12眼（19％）にあった。非発作眼に急性発作が起こる可能性が高いと推定される。両眼発症が男性に多いことから，片眼発作例でも男性には僚眼に急性発作が起こる可能性が高い。

Abstract.　Purpose：To report the difference between unilateral and bilateral cases of acute angle-closure with or without glaucoma. Cases and Method：This retrospective study was made on 75 eyes of 63 cases of acute angle-closure with or without glaucoma seen during the past 25 years. The series comprised 16 males and 59 females. The age ranged from 44 to 85 years,average 67 years. Twelve cases were bilaterally and 51 cases were unilaterally affected. Results：Five males（42％）were bilaterally and 6 males（12％）were unilaterally affected,suggesting no difference in gender in bilateral cases and preponderance of females in unilateral cases. There was no difference between unilateral and bilateral cases regarding age,refraction,axial length,depth of anterior chamber,or lens thickness. Conclusion：There is no difference in anatomy of the eye between unilateral and bilateral cases of acute angle-closure with or without glaucoma. Unilaterally affected males have a higher risk of acute attack in the fellow eye.
