| Summary: |
Purpose: To compare
central corneal thickness (CCT) measurement results
obtained by means of optical and ultrasonic methods.
Setting: Department of Ophthalmology, District Railway
Hospital in Katowice, Poland
Methods: CCT measurement was performed in 35 eyes
(18 patients). All patients undergone exams with use of
an ultrasonic pachymeter – Pocket II (Quantel Medical),
a specular microscope – Topcon SP-2000P (Topcon America
Corporation) and an optical coherence tomography (OCT)
system – Visante OCT (Carl Zeiss Meditec). All exams
were carried out 3 times during the same visit, by one
investigator.
Results: Mean CCT was 535.72 µm ±23.36 (SD)
Visante OCT, 538.42 µm ± 25.27 (SD) with the ultrasonic
device and 522.28 µm ± 23.37 (SD) with the specular
microscope. Visante OCT had the highest reproducibility
– mean difference between measurements was 3 microns.
The difference between results obtained by means of OCT/USG
and spectral microscopy was statistically significant
(p<0.05).
Conclusions: Visante OCT seems to be a very
reliable device to measure CCT, especially as obtained
results are only very slightly influenced by an
investigator. |
