Clinical Applications of Anterior Segment Optical Coherence Tomography

Figure 12

Anterior segment OCT images after trabeculectomies. Vertical and horizontal OCT sections (left column) demonstrate various parameters: internal cavity extent (a), bleb height (b), internal cavity height (c), and bleb wall thickness (d). Right upper images demonstrate thick bleb wall and high internal reflectivity suggesting bleb failure. Right lower images demonstrate relatively thin bleb wall and multiple-layer appearance with low internal reflectivity with good IOP control.
