PURPOSE: To evaluate trabeculectomy blebs by using 3-dimensional anterior segment optical coherence tomography (OCT). METHODS: We prospectively examined 4 eyes of 4 patients who developed filtering blebs after trabeculectomy. A 1310-nm high-speed OCT prototype was used to image the 3-dimensional structure of the filtering blebs. RESULTS: The 3-dimensional structure of the filtering blebs was clearly observed in the OCT images. Three types of filtering blebs were observed: diffuse blebs in 2 eyes, an encapsulated bleb in 1 eye, and a nonfunctioning cystic bleb in 1 eye. The volume of each bleb was 9.97, 1.10, 0.76, and 0.88 mm, respectively. En-face OCT images clearly showed the aqueous outflow channels at the margins of the scleral flaps. CONCLUSION: Three-dimensional OCT allows objective and noninvasive assessment of filtering blebs after trabeculectomy.
