PURPOSE To evaluate preoperative characteristics and follow-up in rural China after trabeculectomy, the primary treatment for glaucoma there. METHODS Patients undergoing trabeculectomy at 14 rural hospitals in Guangdong and Guangxi Provinces and their doctors completed questionnaires concerning clinical and sociodemographic information, transportation, and knowledge and attitudes about glauco...

PURPOSE The purpose of this study was to report a novel model for comparing mechanical resistance to intraocular pressure (IOP) increases with 23-gauge (23G) and 25G transconjunctival sutureless vitrectomy (TSV) sclerotomies in the immediate postoperative period using an experimental model of a vitrectomized eye. METHODS This was a prospective, experimental, randomized, and observer-masked ex...

After tenotomy adjoining 3 o'clock and 9 o'clock limbus, 3-mm-wide partial-thickness scleral tunnels are created at these two diametrically opposite points 3 mm from the limbus such that they reach up to a distance of 1.5 mm from the limbus. Two ab externo sclerotomies are created using 26-G needles on the bed of these partial-thickness scleral tunnels. Precaution is taken to ensure that the po...

Introduction Cataract surgery has undergone various advances since it was evolved from ancient couching to the modern phacoemulsification cataract surgery. Surgically induced astigmatism (SIA) remains one of the most common complications. The introduction of sutureless clear corneal incision has gained increasing popularity worldwide because it offers several advantages over the traditional sut...

PURPOSE To elucidate the potential of three-dimensional anterior segment optical coherence tomography (3D AS-OCT) for identifying filtration openings where aqueous humor flows from the sclera into the subconjunctival space. METHODS We used 3D AS-OCT and custom software to identify filtration openings, which were defined by pits and/or troughs in fluid-filled cavities in both horizontal and ve...
