Intraocular pressure was measured with Goldmann applanation tonometers by two independent examiners in 420 eyes. A difference between measurements of at least 3 mm Hg occurred in 30% of the eyes. Some evidence suggests that the differences between pressure measuremens were caused by actual changes of intraocular pressure rather than by instrument inaccuracy of technician error.
420只眼睛由两名独立检查人员使用戈德曼压平眼压计测量眼压。30%的眼睛测量值之间的差异至少为3毫米汞柱。一些证据表明,眼压测量值之间的差异是由眼压的实际变化引起的,而不是由仪器不准确或技术人员误差导致的。
