Tsutsumi-Kuroda U, et al. - In this retrospective study, researchers explored the impact on trabeculectomy [one of the standard surgical modalities for glaucoma worldwide to prevent visual loss progression by reducing intraocular pressure] the surgical success of early bleb parameters measured by three-dimensional anterior-segment optical coherence tomography. The study sample consisted of 45 patients with 19 of exfoliation glaucoma, 17 of primary open-angle glaucoma, 4 of neovascular glaucoma, 4 of uveitic glaucoma and 1 of glaucoma caused from familial amyloid polyneuropathy who had trabeculectomy. In eyes with open-angle glaucoma, the width of filtration opening at an early stage may be a prognostic factor for the surgical success of trabeculectomy.
