	<span lang=\"EN-US\" style=\"font-family:Verdana;\">Background:</span><span lang=\"EN-US\" style=\"font-family:Verdana;\"> Anterior chamber angle (ACA) can be measured by many different techniques. In
order for a technique to be a part of the routine eye examination, it has to be
quick and easy</span><span lang=\"EN-US\"> </span><span lang=\"EN-US\"><span style=\"font-family:Verdana;\">in
good agreement with gonioscopy both nasally and temporally. </span><span style=\"font-family:Verdana;\">Aim:</span><span style=\"font-family:Verdana;\"> To investigate variation in ACA
measurement between gonioscopy, van Herick technique, anterior segment optical
coherence tomography (AS-OCT) and Sirius Scheimpflug-Camera both nasally and
temporally</span></span><span lang=\"EN-US\" style=\"font-family:Verdana;\">. </span><span lang=\"EN-US\" style=\"font-family:Verdana;\">Method:</span><span lang=\"EN-US\"><span style=\"font-family:Verdana;\"> The ACA of 50 eyes of 25 healthy subjects was
measured with gonioscopy, van Herick technique, AS-OCT and Sirius
Scheimpflug-Camera. The angle was measured both nasally and temporally. </span><span style=\"font-family:Verdana;\">Results:</span><span style=\"font-family:Verdana;\"> No statistically significant
difference could be found between gonioscopy, van Herick technique and AS-OCT
either nasally or temporally. The Sirius Scheimpflug-Camera on the other hand
showed statistically significant difference to gonioscopy (p</span></span><span lang=\"EN-US\"> </span><span lang=\"EN-US\" style=\"font-family:Verdana;\">&lt; 0.0001), van Herick technique (p</span><span lang=\"EN-US\"> </span><span lang=\"EN-US\" style=\"font-family:Verdana;\">&lt; 0.0001) and AS-OCT (p</span><span lang=\"EN-US\"> </span><span lang=\"EN-US\" style=\"font-family:Verdana;\">&lt; 0.0001) both nasally (p = 0.03, p
= 0.001, p</span><span lang=\"EN-US\"> </span><span lang=\"EN-US\" style=\"font-family:Verdana;\">&lt; 0.0001) and
temporally (p = 0.0002, p = 0.001, p</span><span lang=\"EN-US\"> </span><span lang=\"EN-US\"><span style=\"font-family:Verdana;\">&lt; 0.0001). </span><span style=\"font-family:Verdana;\">Conclusion:</span><span style=\"font-family:Verdana;\"> This
study showed good agreement between three of the four techniques. ACA
measurements obtained by the Sirius Scheimpflug-Camera should therefore not be
considered interchangeable with th</span></span><span lang=\"EN-US\" style=\"font-family:Verdana;\">ose</span><span lang=\"EN-US\" style=\"font-family:Verdana;\"> obtained by the remaining three methods.</span>
