Abstract

Anterior segment imaging optical coherence tomography (AS-OCT) can be a useful aid in glaucoma surgery. Recent studies have shown its importance in both the preoperative morphologic evaluation of glaucoma patients as well as postoperative evaluation of filtering bleb functionality. Our purpose is to evaluate post-trabeculectomy filtering and non-filtering bleb characteristics in both time-domain OCT (TD-OCT, Visante (TM), Carl Zeiss) and spectral-domain OCT (SD-OCT, Heidelberg Spectralis (R) anterior segment module), assess the usefulness of AS-OCT in evaluating postoperative filtering bleb function and compare both methods results. AS-OCT as a useful exam in determining functioning and non-functioning bleb characteristics. SD-OCT with an anterior segment module had a better performance in examining fine bleb features and performed better than in previous studies in examining deeper structures.
