背景评价Corvis Scheimpflug技术非接触眼压计测量的眼压和中央角膜厚度的一致性（Corvis ST，OCULUS，韦茨拉尔，德国）对比Goldmann压平眼压计（GAT）和基于超声的角膜厚度测量（US-CCT）。这项前瞻性研究包括了20例高眼压（OHT）患者和20例开角型青光眼患者。在每名参与者中，获得GAT、US-CCT和Corvis ST测量值（Corvis-IOP和Corvis-CCT）。通过相关分析、回归分析、Bland-Altman图和组内相关系数的评估来检验方法的准确性和可重复性。结果188例受试者（142只眼青光眼，10只眼OHT和36只眼对照）的188只右眼被纳入本前瞻性研究。所有入选者的平均GAT为14.5 ± 4.8mmHg，而平均Corvis-IOP为15.4 ± 5.6mmHg（斯皮尔曼r=0.75，p
Background To evaluate the agreement of intraocular pressure (IOP) and central corneal thickness (CCT) measurements obtained with the non-contact tonometer Corvis Scheimpflug Technology (Corvis ST, OCULUS, Wetzlar, Germany) versus Goldmann applanation tonometry (GAT) and ultrasound-based corneal pachymetry (US-CCT).Methods Eye healthy participants, patients with ocular hypertension (OHT) and patients with open-angle glaucoma were included in this prospective study. In each participant, GAT, US-CCT and measurements with Corvis ST were obtained (Corvis-IOP and Corvis-CCT). Accuracy and repeatability were tested by correlation and regression analyses, Bland-Altman plots and assessment of intraclass correlation coefficients.Results A consecutive series of 188 right study eyes of 188 participants (142 eyes with glaucoma, 10 eyes with OHT and 36 control eyes) were included in this prospective study. The mean GAT of all included was 14.54.8mmHg compared with mean Corvis-IOP of 15.4 +/- 5.6mmHg (Spearman's r=0.75, p
