球結膜下出血と緑内障

Subconjunctival hemorrhage and glaucoma

　球結膜下出血131例につき，球結膜下出血と緑内障との関係を検索した。健康診断を受けた正常者125名を対照とした。緑内障の判定は，閉塞隅角緑内障については眼圧，暗室うつむき試験，隅角所見，開放隅角緑内障については負荷試験などを含む眼圧，視野経乳頭陥凹，視野に基づいて行った。球結膜下出血群では，14例が緑内障，23例が緑内障疑診と判定され，対照群では，1例が緑内障，8例が緑内障疑診と判定された。両群での頻度には有意差があった（p＜0.001）。球結膜下出血群では，初発者よりも再発者の緑内障有病率が有意に高かった（p＜0.001）。緑内障有病率は，咳，便秘，目をこするなどの誘因で起こった者よりも，特発的に起こった者で有意に高かった（p＜0.02）。以上の結果から，球結膜下出血と緑内障の間には高い関連があると結論される。

We studied the possible association between subconjunctival hemorrhage and glaucoma. The cases comprised 131 cases of subconjunctival hemorrhage and 125 age-matched healthy persons. Diagnosis of glaucoma was based on the following criteria. Closed-angle glaucoma was diagnosed by intraocular pressure (IOP), darkroom prone test and gonioscopy. Open-angle glaucoma was diagnosed by IOP including provocative tests, disc cupping and visual field. In the group of subconjunctival hemorrhage, 14cases were diagnosed as glaucoma and 23 as glaucoma suspect. In the control group, 1 case was diagnosed as glaucoma and 8 as glaucoma suspect. The difference in the two groups was significant (P＜0.001). In the group of subconjunctival hemorrhage, the incidence of glaucoma was higher in recurrent cases than in first-onset ones (p＜0.001), the incidence in the cases without inducing factors was higher than these with such factors (p＜0.002). The findings show that there is a high correlation between subconjunctival hemorrhage and glaucoma.
