METHODS: Sixty-six eyes of 66 healthy volunteers were enrolled. Three consecutive measurements were performed with each device. The mean value of the three measurements was used for subsequent analysis. Central corneal thickness (CCT), thinnest corneal thickness (TCT), and midperipheral corneal thickness (MPCT; measured at superior, inferior, nasal, and temporal locations with a distance of 1 mm (CT2mm) or 2.5 mm (CT5mm) from the corneal apex) were analyzed. Differences and agreement between measurements were assessed using the repeated-measures analysis of variance (ANOVA) and Bland-Altman analyses, respectively. RESULTS: Statistically significant differences (p{<}0.001) among the four devices were revealed in CCT, TCT and CT2mm measurements. The CCT, TCT, and CT2mm values were ranked from the thickest to the thinnest as follows: Galilei{>}Sirius{>}Pentacam{>}RTVue OCT. For these measurements, agreement between measurements by Sirius and Pentacam was good, whereas Galilei overestimated and RTVue underestimated corneal thickness compared to Sirius and Pentacam. As regards CT5mm measurements, Pentacam provided the largest values, whereas RTVue OCT yielded the smallest values. Agreement of the CT5mm measurements was good between the Pentacam, Sirius, moderate between Galilei and the other two Scheimpflug systems, and poor between the RTVue OCT and the remaining devices. CONCLUSIONS: The Pentacam and Sirius can be used interchangeably for CCT measurements, while the Galilei and RTVue systematically over- and underestimate CCT, respectively. The three Scheimpflug cameras, but not the RTVue, may be used interchangeably for MPCT measurements.", "link"=>"http://www.mendeley.com/research/central-midperipheral-corneal-thickness-measured-scheimpflug-imaging-optical-coherence-tomography-1", "reader_count"=>14, "reader_count_by_academic_status"=>{"Professor > Associate Professor"=>1, "Student > Doctoral Student"=>3, "Student > Ph.

For these measurements, agreement between measurements by Sirius and Pentacam was good, whereas Galilei overestimated and RTVue underestimated corneal thickness compared to Sirius and Pentacam. As regards CT_5mm measurements, Pentacam provided the largest values, whereas RTVue OCT yielded the smallest values. Agreement of the CT_5mm measurements was good between the Pentacam, Sirius, moderate between Galilei and the other two Scheimpflug systems, and poor between the RTVue OCT and the remaining devices.</p><p>Conclusions</p><p>The Pentacam and Sirius can be used interchangeably for CCT measurements, while the Galilei and RTVue systematically over- and underestimate CCT, respectively. The three Scheimpflug cameras, but not the RTVue, may be used interchangeably for MPCT measurements.</p></div>", "links"=>[], "tags"=>["biotechnology", "Medical devices and equipment", "Clinical medicine", "ophthalmology", "Corneal disorders", "midperipheral", "corneal", "thickness", "scheimpflug", "imaging", "optical", "coherence"], "article_id"=>1034678, "categories"=>["Biological Sciences"], "users"=>["Jinhai Huang", "Xixia Ding", "Giacomo Savini", "Zhengxuan Jiang", "Chao Pan", "Yanjun Hua", "Fan Wu", "Yifan Feng", "Ye Yu", "Qinmei Wang"], "doi"=>["https://dx.doi.org/10.1371/journal.pone.0098316.s001", "https://dx.doi.org/10.1371/journal.pone.0098316.s002", "https://dx.doi.org/10.1371/journal.pone.0098316.s003", "https://dx.doi.org/10.1371/journal.pone.0098316.s004", "https://dx.doi.org/10.1371/journal.pone.0098316.s005", "https://dx.doi.org/10.1371/journal.pone.0098316.s006", "https://dx.doi.org/10.1371/journal.pone.0098316.s007", "https://dx.doi.org/10.1371/journal.pone.0098316.s008", "https://dx.doi.org/10.1371/journal.pone.0098316.s009", "https://dx.doi.org/10.1371/journal.pone.0098316.s010", "https://dx.doi.org/10.1371/journal.pone.0098316.s011", "https://dx.doi.org/10.1371/journal.pone.0098316.s012", "https://dx.doi.org/10.1371/journal.pone.0098316.s013", "https://dx.doi.org/10.1371/journal.pone.0098316.s014", "https://dx.doi.org/10.1371/journal.pone.0098316.s015", "https://dx.doi.org/10.1371/journal.pone.0098316.s016"], "stats"=>{"downloads"=>25, "page_views"=>7, "likes"=>0}, "figshare_url"=>"https://figshare.com/articles/_Central_and_Midperipheral_Corneal_Thickness_Measured_with_Scheimpflug_Imaging_and_Optical_Coherence_Tomography_/1034678", "title"=>"Central and Midperipheral Corneal Thickness Measured with Scheimpflug Imaging and Optical Coherence Tomography", "pos_in_sequence"=>0, "defined_type"=>4, "published_date"=>"2014-05-22 03:33:55"}
