摘要

本研究的目的是比较高盛压眼压仪(GAT)和动态轮廓眼压仪(DCT)在改良日张力曲线(mDTC)下治疗青光眼的眼压(IOP)分布。符合条件的受试者按此顺序使用GAT和DCT进入mDTC。IOP测量分别在上午8点、上午10点、下午2点和下午4点进行。上午用超声测厚仪测量角膜中央厚度。统计学分析采用配对Student’st检验和Bland-Altman图。DCT和GAT测量值的平均差异为0.9 mmHg。mDTC期间的平均+/- SD IOP测量值分别为:GAT 19.68 +/- 4.68、17.63 +/- 4.44、17.25 +/- 5.41和17.32 +/- 4.25 mmHg, DCT 19.97 +/- 4.75、18.79 +/- 4.61、19.53 +/- 5.30和19.43 +/- 5.45 mmHg。使用两种眼压计时,IOP测量值在早上(上午8点)较高,全天均下降。使用GAT和DCT测量的IOP之间的差异在早晨较小,并且全天都在增加。GAT的IOP变异性高于DCT。角膜的生物力学特性可能有助于解释我们的发现。

Intraocular pressure profile during the modified diurnal tension curve using Goldman applanation tonometry and dynamic contour tonometry.

The aim of this study was to compare the intraocular pressure (IOP) profile during the modified diurnal tension curve (mDTC) using Goldman applanation tonometry (GAT) and dynamic contour tonometry (DCT) in treated glaucomatous eyes. Eligible subjects were submitted to the mDTC using GAT and DCT in this sequence. IOP measurements were performed at 8 a.m., 10 a.m., 2 p.m., and 4 p.m.. Central corneal thickness was measured using ultrasound pachymetry in the morning. Statistical analysis was performed using paired Student's t test and Bland-Altman plot. The mean difference between DCT and GAT measurements was 0.9 mmHg. The mean +/- SD IOP measurements during the mDTC were 19.68 +/- 4.68, 17.63 +/- 4.44, 17.25 +/- 5.41, and 17.32 +/- 4.25 mmHg using GAT and 19.97 +/- 4.75, 18.79 +/- 4.61, 19.53 +/- 5.30, and 19.43 +/- 5.45 mmHg using DCT. IOP measurements were higher in the morning (8 a.m.) and decreased throughout the day using both tonometers. The difference between IOP measurements using GAT and DCT was smaller in the morning and increased throughout the day. The IOP variability using GAT was higher than using DCT. Corneal biomechanical properties might help explain our findings.
