Case Report: Temporary management of delayed postoperative hypotony with Baerveldt tube: Ab Interno stenting using 3-0 nylon suture
Bibliographic record
Abstract
<ns3:p>Background To describe the management of delayed postoperative hypotony and choroidal detachment in a 79-year-old female patient with advanced pseudoexfoliative open-angle glaucoma. Case The patient, refractory to maximal medical therapy, underwent Baerveldt tube implantation with a ripcord using a 4-0 nylon suture. Ripcord removal and the reintroduction of antiglaucoma medication were initiated in response to a hypertensive phase. Delayed postoperative hypotony and choroidal effusions were managed through ab interno stenting of the tube, employing a 3-0 nylon suture. Ab interno stenting of the tube, employing a short segment of 3-0 nylon suture, initially addressed delayed postoperative hypotony and choroidal effusions. However, recurrence of hypotony and choroidal detachment occurred as the short stent descended into the anterior chamber. To manage the recurrent hypotony, Baerveldt tube truncation was performed, along with re-stenting of the tube using a longer 3-0 Nylon ripcord. Conclusions While ab interno occlusion with a short segment of 3-0 nylon suture may offer temporary hypotony control, the risk of segment descent warranted the use of a longer ripcord to enhance efficacy and stability.</ns3:p>

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
