Tono-Pen眼压计与Goldmann眼压计的临床比较

目的:了解Tono-Pen眼压计的临床实用性。方法:62例(111只眼)随机先后用Tono-Pen眼压计与Goldmann眼压计进行眼压测量,比较两种眼压计测量值的差异。结果:111只眼中,用Goldmann眼压计测量的眼压平均值为(15.82±4.88)mmHg,用Tono-Pen眼压计测量的眼压平均值为(16.34±4.33)mmHg,两者有显著性差异。眼压在9～30mmHg范围时,两种眼压计的测量值之差为(-0.51±2.24)mmHg,差异无显著性。在眼压低于9mmHg时,有过高估计眼压的趋向;在眼压高于30mmHg时,有过低估计眼压的趋向。Tono-Pen眼压计与Goldmann眼压计的相关系数为0.865,呈密切相关。结论:Tono-Pen眼压计与Goldmann眼压计有很好的相关性,尤其是在眼压为9～30mmHg范围。眼科学报 2002;18:226-229.

Clinical Comparison of the Tono-Pen Tonometer to the Goldmann Applanation Tonometer

PURPOSE: To compare the Tono-Pen tonometer with the Goldmann applanation and assess the precision and accuracy of the Tono-Pen tonometer. METHODS: 62 cases (111 eyes) were random measured with the Tono-Pen tonometer and the Goldmann applanation tonometer. RESULTS: Overall we found that 74.8% of the Tono-Pen readings were within +/- 2 mmHg of the Goldmann applanation readings and 83.8% were within +/- 3 mmHg. The correlation coefficient between the readings of the two instruments was 0.865. The mean value of the paired differences was (-0.51 +/- 2.24)mmHg in the 9 to 30 mmHg interval. CONCLUSION: The Tono-Pen tonometer measures intraocular pressure in a manner that corresponds well to the Goldmann applanation tonometer, especially in the 9 - 30 mmHg interval. But this tonometer may overestimate the intraocular pressure in eyes with low intraocular pressure, and underestimate the intraocular pressure in eyes with high intraocular pressure.
