Article Synopsis
- The study examines how trabeculectomy affects the morphology of Schlemm's canal, to potentially use it as a measure for surgical success in treating open-angle glaucoma.
- A total of 35 eyes from patients undergoing trabeculectomy were evaluated using anterior segment optical coherence tomography (AS-OCT) before and after the surgery at various intervals.
- Results showed that the nasal quadrant of Schlemm's canal exhibited a significant increase in size in the days and weeks following surgery, particularly in coronal diameter, indicating early postoperative changes.
Article Synopsis
- - The study aimed to assess long-term structural changes in the anterior chamber (AC) angle after a specific glaucoma surgery called gonioscopy-assisted transluminal trabeculotomy (GATT).
- - Ten eyes that had undergone GATT at least six years prior were examined, revealing various cleft appearances (open, closed, segmentally open) and a noteworthy trend of the trabecular flap moving toward the incision site, resulting in some clefts appearing closed over time.
- - The researchers concluded that combining anterior segment optical coherence tomography (AS-OCT) with gonioscopy provided valuable insights into these structural changes, with mostly preserved clefts in the superior part of the AC angle long-term.
Purpose: To compare the intraocular pressure (IOP)-lowering efficiency of gonioscopy-assisted transluminal trabeculotomy (GATT) and trabeculectomy (TRAB) with mitomycin C in patients with primary open-angle glaucoma (POAG) and pseudoexfoliative glaucoma (PEXG).
Methods: In this retrospective comparative study, consecutive patients with POAG or PEXG who underwent GATT or TRAB by a single surgeon and with a follow-up period of at least 1 year were included. Surgical success rates, change in best-corrected visual acuity, IOP, the need for antiglaucoma medication, surgical complications, and the need for additional glaucoma surgery were compared.
We introduce Ultra-Flexible Tentacle Electrodes (UFTEs), packing many independent fibers with the smallest possible footprint without limitation in recording depth using a combination of mechanical and chemical tethering for insertion. We demonstrate a scheme to implant UFTEs simultaneously into many brain areas at arbitrary locations without angle-of-insertion limitations, and a 512-channel wireless logger. Immunostaining reveals no detectable chronic tissue damage even after several months.

Study Design: Prospective observational study.
Methods: This study included cases with refractory glaucoma that underwent AGV implantation with PPG coverage.
