Forty-five patients with poorly controlled chronic open angle glaucoma underwent pneumotonography immediately prior to argon laser trabeculoplasty. The coefficient of facility of outflow (c-value) was calculated from the pneumotonography and correlated with the intraocular pressure rise one hour after the argon laser trabeculoplasty. It appeared that there was a strong relationship between a low c-value indicating a poor outflow facility and a large intraocular pressure rise following argon laser trabeculoplasty. The implications of being able to predict the intraocular pressure rise after argon laser trabeculoplasty are discussed.
45例慢性开角型青光眼控制不佳的患者在氩激光小梁成形术前立即接受了气动眼压描记法检查。根据气动眼压描记法计算房水流畅系数（c值），并将其与氩激光小梁成形术后1小时的眼压升高情况进行相关性分析。结果显示，低c值表明房水流出功能不佳，与氩激光小梁成形术后眼压大幅升高之间存在密切关系。文中讨论了能够预测氩激光小梁成形术后眼压升高的意义。
