PURPOSE: Ultrasound biomicroscopy (UBM) was performed on filtering blebs with laser treatment including laser gonioplasty (GP), laser iridotomy (LI), and YAG laser trabeculopuncture (YLT) after non-penetrating trabeculectomy (NPT). The filtering blebs were grouped into four types, L, H, E and F, and the spaces under the scleral flap were classified into three, La, S, and N. CASE REPORTS: In case 1, an F type, an S bleb was not changed despite laser treatment nine months after NPT. In case 2, YLT was performed twice to release the incarcerated iris. The filtering bleb was changed to the L type, an La bleb. In case 3, an F type, an S bleb was turned into an H type after GP, LI, and YLT. In case 4, GP effectively released peripheral anterior synechia formation and the filtering bleb was kept as an L type, La. CONCLUSION: Appropriate laser treatment may be effective in turning a flattened and localized bleb into a good filtering bleb.LA: Japanese
