Comparison of Internal Anterior Chamber Diameter Imaging Modalities: 35-MHz Ultrasound Biomicroscopy, Visante Optical Coherence Tomography, and Pentacam
PURPOSE
To compare the internal diameter of the anterior chamber among three different imaging modalities: 35-MHz ultrasound biomicroscopy (UBM), Visante optical coherence tomography (OCT), and Pentacam, and to compare the internal diameters with white-to-white (WTW) distance measured by Orbscan.
METHODS
The internal horizontal anterior chamber diameter was measured in 20 normal eyes using 35-MHz UBM (Optikon), Visante OCT (Carl Zeiss Meditec), and Pentacam (Oculus Inc). The mean horizontal anterior chamber diameters were compared, and the correlations between each pair of two different methods were evaluated. Horizontal WTW distance was measured by Orbscan IIz (Bausch & Lomb-Orbtek Inc) and then correlated ...
