In infantile glaucoma Schiotz and Perkins tonometry are often divergent. However, empirical data about the quantitative relation of Schiotz' and Perkins' measurements are lacking for this group of patients.
363 comparative IOP measurements by applanantion and indentation tonometry under general anesthesia were performed in 51 children (0-10 years) with infantile glaucoma during 01/01/88 and 30/06/95 at the University Eye Clinic Cologne.
Correlation coefficient of both methods was 0.75 (p < 0.001). Schiotz tonometry surmounted Perkins tonometry in 78.8% of measurements. Differences of Schiotz and Perkins IOP measurements showed a normal distribution with mean value 4.37 +/- 5.8 mm Hg. Discrepancy between both methods increased significantly (p < 0.001) in eyes with corneal opacities (5.29 +/-6.35 mm Hg) compared with clear cornea (3.40 +/- 4.98 mm Hg). Discrepancy of Schiotz-Perkins tonometry was not influenced by axial length of the eye, corneal diameter and age of the patient.
Marked discrepancy of applanation and indentation tonometry in infantile glaucoma is frequent. Decision for surgery should not base on tonometry alone, but on evaluation of additional clinical criteria like optic disc cup, corneal morphology and individual anamnesis.
在婴儿型青光眼患者中，Schiotz眼压计和Perkins眼压计的测量结果常常不一致。然而，对于这组患者，缺乏关于Schiotz眼压计和Perkins眼压计测量值定量关系的实证数据。
1988年1月1日至1995年6月30日期间，在科隆大学眼科诊所对51例（0 - 10岁）婴儿型青光眼患儿在全身麻醉下进行了363次应用压平眼压计和压陷眼压计的对比眼压测量。
两种方法的相关系数为0.75（p < 0.001）。在78.8%的测量中，Schiotz眼压计测量值高于Perkins眼压计。Schiotz眼压计和Perkins眼压计测量值的差异呈正态分布，平均值为4.37±5.8 mmHg。与透明角膜（3.40±4.98 mmHg）相比，角膜混浊眼两种方法的差异显著增加（p < 0.001）（5.29±6.35 mmHg）。Schiotz - Perkins眼压计的差异不受眼轴长度、角膜直径和患者年龄的影响。
婴儿型青光眼中压平眼压计和压陷眼压计的测量结果存在明显差异很常见。手术决策不应仅基于眼压测量，还应基于对视盘杯、角膜形态和个体病史等其他临床标准的评估。
