正常人における眼圧と血圧の関係

Relationship between intraocular and blood pressure in normal persons

要約　目的：正常人での眼圧と血圧の関係と，眼圧に影響する因子の報告。対象と方法：健康診断を兼ねた緑内障検診の参加者のうち，異常なしと判定された543人を対象とした。男性312人，女性231人で，年齢は30～80歳（平均53歳）である。結果：血圧が高いほど眼圧が高かった（収縮期：p＝0.013，拡張期：p＝0.044）。眼圧は，女性よりも男性が高く（p＜0.0001），体脂肪係数（BMI）と正の相関があり（p＝0.0001），近視の度数と正の相関があった（p＝0.0004）。眼圧は，年齢または血液のHbA_1c値とは相関しなかった。結論：正常人では血圧が高いほど眼圧が高い。血圧は眼圧に影響する因子である。

Abstract.　Purpose：To report the relationship between intraocular pressure（IOP）and systemic blood pressure,and factors related to IOP. Cases and Method：This study was made on 543 adults who were found to be normal after healthy-check program including glaucoma. The series comprised 312 males and 231 females. The age ranged from 30 to 80 years,average 53 years. Results：IOP was positively correlated with blood pressure during systole（p＝0.013）and diastole（p＝0.044）. IOP was higher in males than females（p＜0.0001）. IOP was positively correlated with body mass index（BMI）（p＝0.0001）and with the degree of myopia（p＝0.0004）. IOP was not significantly correlated with age or HbA_1cvalue in the circulating blood. Conclusion：IOP is positively correlated with systolic or diastolic blood pressure. Blood pressure is a factor that influences IOP in normal adults.
