Anterior segment optical coherence tomography is a rapid, non-contact method of assessing anterior segment structures and has high reliability and repeatability. Three cases are presented to illustrate how this technology can be used in the assessment and management of a glaucoma drainage implant. Anterior segment optical coherence tomography provides high-resolution images of the glaucoma drainage implant to assess its position, patency, drainage, and the intraluminal stenting suture. This proved to be useful in the case of postoperative hypotony. The non-contact advantage is useful in pediatric patients.
