Three screening parameters for glaucoma are automatically displayed in the General Overview display of
the Pentacam: Anterior chamber angle, anterior chamber depth and anterior chamber volume. Angles
measurement data will be displayed for all the images, however sometimes and eyelid for example may
obstruct the angle being displayed, resulting in the specific image to have an extrapolated rather than
measured angle. But as mentioned above the Pentacam measures three parameters aiding in glaucoma
screening and in a study by Grewal et al. it was shown that anterior chamber volume is a more sensitive
parameter than chamber angles.
