We measured the intraocular pressure (IOP) of 50 normal, cooperative, awake children below 5 years of age and 12 normal, volunteer adults with the Perkins hand-held applanation tonometer (Perkins) and the Digilab pneumatonographer-tonometer (Pneuma). Neither sedation, general anesthesia, nor lid specula were used. We confirmed others' findings that the normal IOP, measured in the supine position with the Perkins, is lower in infants and young children (mean = 5.89 mm Hg) than in adults (mean = 13.21 mm Hg; P < .0001). On the other hand, with the Pneuma, the supine pediatric IOP (mean = 14.76 mm Hg) was not significantly different from the adult sitting IOP (mean = 14.42 mm Hg; P = .497). Regression analysis suggests that children and adult Perkins IOP may become equal at around age 12 years.

我们使用Perkins手持式压平眼压计 (Perkins) 和Digilab气动眼压计 (Pneuma) 测量了50名5岁以下正常,合作,清醒的儿童和12名正常的志愿者成年人的眼压 (IOP)。既不使用镇静,全身麻醉也不使用盖子。我们证实了其他人的发现,即在Perkins仰卧位测量的正常IOP在婴儿和幼儿 (平均 = 5.89毫米Hg) 中比成人 (平均 = 13.21毫米Hg; P < .0001) 低。另一方面,对于肺炎,仰卧小儿IOP (平均 = 14.76毫米Hg) 与成人坐位IOP (平均 = 14.42毫米Hg; P = .497) 没有显着差异。回归分析表明,儿童和成年Perkins IOP可能在12岁左右变得平等。
