Purpose: To investigate the reason for failure of trabeculotomy using trabeculectomy (TLE) specimens involving the area of previous trabeculotomy.
Materials And Methods: Thirteen TLE specimens from 13 patients with open-angle glaucoma were processed for transmission electron microscopy and light microscopy, involving immunohistochemical staining of thrombomodulin, D2-40 (podoplanin), and CD34.
Results: All intraocular pressure after trabeculotomy decreased to normal and then returned to the same or a higher level compared with that before TLE.
Objective: To determine whether previous phacoemulsification adversely affects surgical prognosis of trabeculectomy with mitomycin for open-angle glaucoma.
Methods: The study is a retrospective, consecutive, comparative case series. At 2 clinical centers, we reviewed 226 medical records of eyes with open-angle glaucoma undergoing initial trabeculectomy, including 175 phakic eyes (phakic group) and 51 pseudophakic eyes that had previously undergone phacoemulsification with superior conjunctival incision (pseudophakic group).
Purpose: To investigate the dependence upon intraocular pressure (IOP) of the progression of visual field defects in eyes with primary open-angle glaucoma (POAG), in which the mean IOP was maintained at < or =21 mm Hg.
Methods: This study involved 100 eyes with POAG, which were followed up for > or =5 years. The mean IOP levels were maintained at < or =21 mm Hg during the follow-up period.

Purpose: To investigate ultrastructural changes in the aqueous outflow route and discuss the mechanisms associated with intraocular pressure (IOP) elevation in a patient with presumably early stage Chandler's syndrome.
Methods: A 47-year-old man underwent trabeculectomy because of elevated IOP. A specimen obtained during surgery was studied by transmission electron microscopy.
Objectives: To study the ultrastructure of the trabecular meshwork in human eyes with corticosteroid-induced glaucoma and to determine whether the changes noted also occur in the eyes of patients with primary open-angle glaucoma (POAG) who have been treated with corticosteroids.
Methods: The trabecular meshwork from 5 patients in whom corticosteroid-induced glaucoma was diagnosed and from 6 patients with POAG who had been treated with systemic or topical corticosteroids for months to years was investigated with light and electron microscopy. None of the eyes with POAG were considered to have corticosteroid-induced elevation of the intraocular pressure.
