Abstract

PURPOSE: To compare the measurement of the central corneal thickness (CCT) by Visante (Carl Zeiss Meditec, Dublin, California, USA) anterior segment optical coherence tomography (AS-OCT) with ultrasound pachymetry. DESIGN: Population-based, cross-sectional study. METHODS: Participants were part of a population-based study of 3280 Malay subjects aged 40 to 80 years in Singapore. Ultrasound pachmetry of CCT was performed on all participants and approximately 10% underwent further evaluation with AS-OCT. RESULTS: Two hundred and eighty-five consecutive subjects were included, with a mean age of 57.9 (+/- 10.8) years. CCT as measured by ultrasound pachymetry was highly correlated with the equiva..
