A clinical evaluation of two new portable tonometers, the Oculab Tono-Pen and the Keeler Pulsair, was performed to determine their accuracy and efficacy. Measurements were obtained in 229 eyes of 130 normal patients and compared to measurements obtained with the Goldmann applanation tonometer. The average absolute deviation for the Tono-Pen and the Pulsair was a significant 2.70 mm Hg and 2.49 mm Hg, respectively. Thirteen of 188 (7%) Tono-Pen readings and 19 of 229 (8%) Pulsair readings differed from the Goldmann readings by more than 5 mm Hg. Both instruments were highly sensitive and specific for detecting intraocular pressures greater than 21 mm Hg.
对两款新型便携式眼压计——Oculab Tono-Pen和Keeler Pulsair进行了临床评估，以确定其准确性和有效性。对130名正常患者的229只眼睛进行了测量，并与使用Goldmann压平眼压计获得的测量结果进行比较。Tono-Pen和Pulsair的平均绝对偏差分别为显著的2.70毫米汞柱和2.49毫米汞柱。188次Tono-Pen读数中有13次（7%），229次Pulsair读数中有19次（8%）与Goldmann读数的差异超过5毫米汞柱。两款仪器在检测眼压高于21毫米汞柱时都具有高度的敏感性和特异性。
