目的：利用三维前段光学相干断层扫描（OCT）评价小梁切除术后的气泡。方法：对4例小梁切除术后出现滤过性水泡患者的4只眼进行前瞻性检查。利用1310nm高速OCT原型机对滤泡的三维结构进行成像。结果：OCT图像清晰可见滤泡的三维结构。3种滤过性泡：2只眼为弥漫性泡，1只眼为囊性泡，1只眼为无功能囊性泡。每个气泡的体积分别为9.97、1.10、0.76和0.88mm(3)。正面OCT图像清晰显示在巩膜瓣边缘有水流出通道。结论：三维OCT可以客观、无创地评估小梁切除术后滤过泡。
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 highspeed 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 I eye, and a nonfunctioning cystic bleb in 1 eye. The volume of each bleb was 9.97, 1.10, 0.76, and 0.88mm(3), 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.
