Abstract Details


To study the repeatability and reproducibility of a convertible optical coherence tomographer (OCT) to measure anterior segment distances, and assess its agreement with a Scheimpflug camera.


Unit of Optometry, Department of Clinical Neuroscience, Karolinska Institutet, Stockholm, Sweden.


Eighty phakic eyes were measured in this study, and each eye was measured three times with the Sirius (Costruzione Strumenti Oftalmici, Florence, Italy) and the Cirrus HD-OCT 5000 (Carl Zeiss Meditec, Jena, Germany). This latter device is a high resolution retinal OCT that includes an anterior segment module to convert it into an anterior segment one. The agreement and precision of these devices were assessed to measure the internal anterior chamber depth (ACD), angle to angle, thinnest and apex pachymetry, and nasal and temporal angles.


The Cirrus OCT measured on average shallower ACD, smaller angle to angle, thinner pachymetry, and narrower temporal angle than the Sirius. Nevertheless, the OCT measured wider nasal angle than the Sirius system. Both devices showed similar repeatability and reproducibility metrics to measure the ACD, corneal pachymetry, and anterior chamber angles. Nevertheless, the reproducibility of the OCT to measure the angle to angle was worse than the Sirius camera, which values were 0.11 and 0.21 mm, respectively.


The Cirrus and Sirius systems showed good repeatability and reproducibility values to measure the anterior eye segment. Nonetheless, clinical criteria are needed to judge whether these devices could be used interchangeable.
