Case Report: Xen Ab Interno Gel Stent Use in a Refractory Glaucoma Patient With Previous Filtration Surgeries
Bibliographic record
Abstract
This case study reports the successful implantation of the Xen ab interno gel stent in a 44-year-old man with refractory chronic open-angle glaucoma. The patient had multiple unsuccessful filtration surgeries including a trabeculectomy and 2 Ahmed glaucoma valves placed superotemporally and inferonasally oculus dexter. The patients intraocular pressure was reduced from 29 mm Hg preoperatively to 17 mm Hg 1 year after surgery, without any ocular complications. The Xen gel stent may be considered as a possible intervention to lower intraocular pressure in patients with refractory glaucoma, despite previous filtration surgeries if the superonasal conjunctiva is spared and healthy.

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.
