Anterior chamber depth measurements in phakic and pseudophakic eyes: Pentacam versus ultrasound device

Abstract

In phakic eyes, ACD measured with the Pentacam and with US was the same. However, in pseudophakic eyes, the difference was significantly lower when the ACD was measured with the Pentacam. Therefore, in pseudophakic patients, further evaluation of ACD data with the Scheimpflug-based system is necessary.

Repeatability, reproducibility, and agreement of central anterior chamber depth measurements in pseudophakic and phakic eyes: Optical coherence tomography versus ultrasound biomicroscopy

“…However, ACD measurements in pseudophakic eyes have not been fully evaluated. [20][21][22] At present, ultrasound contact A-scan is widely used in these eyes. However, possible disadvantages of this conventional method include corneal indentation, a relatively low resolution, and moderate precision.…”

Assessment and reproducibility of anterior chamber depth measurement with anterior segment optical coherence tomography compared with immersion ultrasonography

“…Our ACD values by the immersion US technique were the same as those in a study of the Orbscan by Auffarth et al 24 In our study, immersion US central ACD values were significantly lower than AS-OCT values; however, our data are comparable to those in the literature. 7,[18][19][20][21][22][23][24][25][26][27] In the study by Baikoff et al, 18 the ACD was shallower with the IOLMaster (Carl Zeiss) than with a prototype of the Zeiss AS-OCT, and a high correlation (r 2 Z 0.71) was observed between the 2 devices. In our study, the ACD was smaller with Visante OCT than Baikoff et al's data indicate, but we used different software.…”

Variability of axial length, anterior chamber depth, and lens thickness in the cataractous eye

“…However, the graphs in Figures 7 and 10 show a large scatter of ACD. In 2 comparative studies, Nemeth et al 13,14 found a mean ACD measurement of 2.87 G 0.4 mm in 1 study and 2.95 G 0.34 mm in the other. Both studies used immersion ultrasonography.…”
