Description

Precise estimation of central corneal thickness (CCT) is highly important to plan corneal refractive surgeries, to diagnose and manage glaucoma and corneal diseases. The purpose of the study was to assess correlation and agreement in CCT obtained by Heidelberg Anterion, Heidelberg Spectralis and Optovue AngioVue optical coherence tomography (OCT). . This was a prospectively designed study conducted on normal subjects recruited from the Pauls Stradiņš Clinical University Hospital. All subjects underwent Heidelberg Anterion, Heidelberg Spectralis and Optovue AngioVue OCT pachymetry on both eyes. Statistical analysis was performed using MS Excel and IBM SPSS 27. Intraclass correlation (ICC) estimates and their 95% confidence intervals were calculated based on a single-rating, absolute agreement, 2-way mixed effects model. The 95% limits of agreement (LoA) and Bland-Altman plots were used.. This study enrolled 60 eyes of 30 subjects with no previous ocular surface disease. 63% (n=19) of subjects were female and 37% (n=11) were male. The median age was 57 years (range 25 to 88 years). The mean CCT measured by Heidelberg Anterion, Heidelberg Spectralis and Optovue AngioVue were 542 μm (SD=37), 535 μm (SD=35) and 536 μm (SD=36), respectively. ICC coefficient >0.97 (p
