Glaucoma Tube Imaging Using Anterior Segment Optical Coherence Tomography in Patients With Opaque Cornea
Kiddee W; Trope GEJournal of Glaucoma 2013; 22: 773-775
PURPOSE: Anterior segment optical coherence tomography (AS-OCT) was used to diagnose Ahmed tube tip patency in patients with opaque corneas after corneal transplantation and tube shortening. MATERIALS AND METHODS: Noncomparative observational case series: 3 consecutive patients with nonvisualized tubes and uncontrolled intraocular pressure after corneal transplantation underwent AS-OCT to determine tube tip patency. RESULTS: In each case, AS-OCT allowed for imaging of the tube position, wall passage, and osteum patency that could not be visualized on gonioscopy. Two of 3 tubes were found to be nonpatent. CONCLUSIONS: High-resolution noncontact cross-sectional AS-OCT images provide information on tube position and patency in the presence of opaque media after corneal transplantation, assisting with clinical decision-making.
