Ab interno suture tube occlusion of the Baerveldt glaucoma implant for management of postoperative hypotony: A case series
Bibliographic record
Abstract
Delayed hypotony can be a vision threatening complication following aqueous shunt surgery in patients with glaucoma. Multiple medical and surgical management strategies have been utilized, but results have been inconsistent. The present case series describes management of delayed hypotony associated with the Baerveldt glaucoma implant (BGI) by surgically introducing 4-0 polypropylene suture into the tube lumen. The cases of four patients who presented with hypotony following BGI surgery were reviewed. Following BGI tube lumen occlusion with suture, sustained intraocular pressure increase (mean 7.25 mmHg, range 4–14) was noted in all patients and visual acuity improved in three cases. This is the first report of ab interno suture occlusion of the BGI for management of post-operative hypotony. Further studies are required to determine the utility of this procedure, but our results suggest that in select patients, ab interno suture occlusion be advantageous in managing delayed hypotony refractive to medical therapy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
