Swept source anterior segment OCT
Reviewed by Lorraine North

The authors describe a study using the Casia OCT which is a swept source OCT to determine the visibility of the angle structures using two imaging protocols; high density and low density. They randomly selected one eye from 30 normal subjects and 30 primary open angle glaucoma subjects to image. They found high interobserver agreement for assessment of visibility of the angle structures and in particular the scleral spur, swalbes line and schlemm’s canal could all be identified. However, this was dependent on the imaging protocol chosen and the quadrant imaged.
