Correlation of corneal thickness measurements between tono-pachymeter and scheimpflug-placido topography
Central corneal thickness (CCT) measurements are important for diagnosis,treatment, and surgery planning in ophthalmology. The purpose of this study was to see whether CCT measurements taken with Tono-pachymeter and Scheimpflug-Placido Topography had any significant differences. Tono-pachymeter an...

| description | Central corneal thickness (CCT) measurements are important for diagnosis,treatment, and surgery planning in ophthalmology. The purpose of this study was
to see whether CCT measurements taken with Tono-pachymeter and Scheimpflug-Placido Topography had any significant differences. Tono-pachymeter and
topography CCT measurements were taken (n=400). Inter-measurement
agreement between them was determined using Bland-Altman Plot analysis. Age
groups were also formed as group 1 (aged 18-50 years, 94 males, 106 females) and
group 2 (age >51 years, 100 males, 100 females). Mean CCTs measured by Tono-pachymeter and topography were 563.77 +±26.43 and 560.88 + 26.341 microns.
Bland-Altman Plot analysis showed in total, 13 were above the upper limit and
5 were under the minimum limit of agreement with regression analysis showing
no significant relationships (p=0.213). Group 1 had 7 above and 2 below from
the limits of agreement. Group two had 9 above and 2 below from the limits of
agreement. Both groups showed insignificant differences between devices (p=0.07
and p=0.86). Tono-pachymeter and Scheimpflug-Placido Topography give reliable
CCT results within each other. However, since the limit of agreement ranges can
still affect one-to-one patient evaluations, we recommend clinics that use these
devices to not interchange measurements in practice. |
