目得：比较Pentacam综合眼扫描仪（CES）、非接触角膜内皮显微镜（SM）和超声角膜厚度测量仪（UP）在正常和圆锥角膜中测量的中央角膜厚度（CCT）。在一项前瞻性研究中，使用Pentacam CES，SM，A组45例近视患者和B组62例圆锥角膜患者的1只眼的UP序列。结果：PentacamCES（r = 0.994）和UP（r = 0.993）在A组中具有很高的重复性，且与A组相当;在B组中，Pentacam CES显示出更好的重复性（r = 0.988），而UP（r = 0.969）和SM（r = 0.901）。Pentacam CES和UP的平均CCT测量值在A组（P =.37）和轻度圆锥角膜患者（P =.29）中无显著差异，而在B组和中度及重度圆锥角膜患者（P
PURPOSE: To compare central corneal thickness (CCT) measurements taken with the Pentacam comprehensive eye scanner (CES), noncontact specular microscopy (SM), and ultrasound pachymetry (UP) in normal and keratoconic corneas.SETTING: Department of Ophthalmology, Ankara University School of Medicine, Ankara, Turkey.METHODS: In a prospective study, 3 CCT measurements were taken with the Pentacam CES, SM, and UP in that sequence from 1 eye of 45 consecutive patients with myopia (group A) and 62 consecutive patients with keratoconus (group B). Eyes with keratoconus were further divided into 3 subgroups, mild, moderate, and severe, according to the mean keratometry readings.RESULTS: Pentacam CES (r = 0.994) and UP (r = 0.993) demonstrated very high and comparable reproducibility in group A. In group B, Pentacam CES displayed better reproducibility (r = 0.988) than UP (r = 0.969) and SM (r = 0.901). The mean CCT measurements of Pentacam CES and UP were not significantly different in group A (P = .37) and in eyes with mild keratoconus (P = .29), whereas significant differences between all instrument pairs were evident in group B and in moderate and severely keratoconic eyes (P
