摘要
目的:用Tono-Pen眼压计测量眼球各部位眼压值。方法:正常人及无角膜病变的青光眼患者61例99眼,用Tono-Pen眼压计依次测量角膜中心、角膜缘及颞上侧角膜缘后4mm巩膜壁眼压值。结果:角膜中心眼压为(2.52±0.74)kPa,角膜缘为(2.63±0.79)kPa,巩膜壁为(4.46±1.49)kPa。角膜中心和角膜缘眼压差异无统计学意义,而巩膜壁眼压高于角膜中心。角膜中心及巩膜壁眼压呈正相关(r=0.542,P=0.000)。以Y为角膜中心眼压值,X为巩膜壁眼压值,则当X≤2.793kPa,直线回归方程为Y=1.824+0.104X;当X>2.793kPa(高眼压)时,Y=1.493+0.359X。结论:使用Tono-Pen眼压计测量眼压时,巩膜壁眼压值可为真实眼压值提供可靠参考;角膜任何部位均可测得准确眼压值。
Tono-Pen applanation tonometer; intraocular pressure; sclera; central cornea; corneal limbus Abstract Aim ： To explore the difference in intraocular pressure（IOP） on different part of the eye ball measured by Tono-Pen applanation tonometer. Methods： IOP on central cornea,limbus and sclera of 61 cases（99 eyes） were measured by Tono-Pen applanation tonometer. Results： IOP on central cornea, limbus and sclera were （2. 52±0. 74 ） kPa, （ 2.63 ± 0.79） kPa, （4.46 ±1. 49 ） kPa, respectively. There was no statistical difference between the IOP on central cornea and the limbus（P 〉0.05）. IOP on sclera was higher than that on corneal center,and they were positively correlated （r=0.542,P=0.000）. The linear equation was Y= 1. 824 ＋0. 104X（X≤2.793 kPa） and Y= 1.493 ＋0.359（X 〉 2. 793 kPa） （Y： IOP on centralcornea;X： IOP on sclera）. Conclusion ：IOP on sclera measured by Tono-Pen is reliable; IOP measured by Tono-Pen at any part of cornea is accurate.
