Glaucoma tube imaging using anterior segment optical coherence tomography in patients with opaque cornea.
Kiddee Weerawat, Trope Graham E
AI Summary
AS-OCT successfully imaged glaucoma tube patency in opaque corneas post-transplant, revealing non-patent tubes in two of three cases. This non-invasive tool aids clinical decisions when direct visualization is impossible.
Abstract
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.
