Late Bleb Leak Management With Trabeculectomy Shutdown, Baerveldt Glaucoma Device Implantation, and Titratable Tube Lumen Size
Bibliographic record
Abstract
PURPOSE: To report a case of late subconjunctival bleb leak, and its management to preserve vision and achieve optimal pressure control in a patient with advanced glaucoma, a 3+ Seidel positive bleb leak, and hypotony maculopathy in the better-seeing eye. DESIGN: Case Report. METHODS: Shutdown of the earlier trabeculectomy site with a scleral graft was achieved before insertion of a 250-mm Baerveldt glaucoma device. An absorbable ligature was used around the tube to prevent early postoperative hypotony. Additional pressure control was obtained by using a permanent polypropylene ligature to decrease the effective lumen size after the resorbence of the vicryl ligature. This suture was left in a location that would be accessible to laser suture-lysis, or manual removal if necessary. RESULTS: Intraocular pressure at 1 year postoperatively was 13 mm Hg on no medications with resolution of the macular folds and 3 lines of improvement of Snellen corrected distance visual acuity. The leak was completely resolved. CONCLUSION: Excellent pressure control was achieved in the surgical management of a late onset bleb leak by shutting down the old trabeculectomy, and inserting a new Baerveldt tube shunt with an adjustable lumen size.

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.
