Purpose Of Review: Trabeculectomy continues to be the most effective incisional surgery for uncontrolled glaucoma. Since its introduction by Cairns in 1968, the procedure has undergone numerous modifications. This article will summarize the current variations of glaucoma filtration surgery and evidence-based review of their potential advantages and disadvantages.
Recent Findings: Recent innovations in glaucoma filtration surgery have focused on wound modulation to enhance long-term surgical outcomes and the search for a small incision surgery with more predictable outcomes, lower complication rates, and rapid visual recovery. Amniotic membranes, antivascular endothelial growth factor agents, and tissue-engineered biodegradable implants are currently being investigated as alternatives to mitomycin C and 5-fluorouracil to reduce inflammation and subsequent bleb failure with fewer complications. The Ex-PRESS glaucoma filtration device appears promising with its unique feature of small-incision surgery, fewer intraoperative and postoperative complications, and its ability to lower intraocular pressure significantly, which appears to be comparable with standard trabeculectomy.
Summary: Knowledge and surgical expertise in handling current variations of glaucoma filtration surgery are essential to offer an individualized approach with the overall goal of optimizing surgical outcomes and minimizing complications.

Altwijri and Alsirhy reported a case of uveitis-glaucoma-hyphema syndrome after an Ahmed glaucoma valve implantation surgery in an advanced primary open-angle glaucoma patient, being the first ever recorded of its kind. The author describes the position of the tube as the origin of the anterior chamber inflammation and hyphema, which resolved shortly after shortening and relocating it. This publication emphasizes the importance of precise implant positioning and close-up patient follow-up after glaucoma filtration surgery as an important standard for healthcare providers.

: We evaluated the 3-year effectiveness and safety of XEN45, combined or not with phacoemulsification, in patients from the Italian XEN-Glaucoma Treatment Registry. : Data from glaucoma patients who underwent XEN45 alone or combined with phacoemulsification were analyzed. Changes in intraocular pressure (IOP) and the number of ocular hypotensive medications (OHMs) were tested with repeated measures ANOVA in last observation carried forward (LOCF) and per-protocol (PP) analyses.

Glaucoma and cataract often coexist. Patients with both conditions who qualify for surgical treatment may undergo either a combined surgical procedure or sequential treatments such as cataract surgery followed by an antiglaucoma procedure. A combined procedure with phacoemulsification is related to an increased risk of fibrosis of the filtering bleb; however, it is a rational approach for patients with high intraocular pressure and clinically significant lens opacification.
