a Typical OCT images of the successful bleb with wide filtration opening at 2 weeks after trabeculectomy. The red and blue lines represent the horizontal and vertical axes, respectively. The yellow line indicates the z-axis of the data for C-scan images. The cross points of the colored lines show filtration openings, that continued to neighboring horizontal sections (not shown). IOP was 10 mmHg at 1 year after trabeculectomy without additional surgery or medication. b Typical OCT images of the failing bleb with no detectable filtration opening at 2 weeks after trabeculectomy. This case required needling bleb revision at 2 weeks after trabeculectomy
