Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) in Postpenetrating Keratoplasty Steroid-induced Glaucoma: A Case Report
Bibliographic record
Abstract
Glaucoma following penetrating keratoplasty (PKP) remains the leading cause of blindness following PKP. Patients with post-PKP glaucoma can be managed medically and surgically. Evidence studying glaucoma surgical techniques following PKP is limited, but suggests the possibility for high-risk complications, including graft failure. Minimally invasive glaucoma surgeries offer an alternative. We report the first case of post-PKP glaucoma managed with gonioscopy-assisted transluminal trabeculotomy (GATT). The patient was a 33-year-old man with a history of keratoconus who underwent PKP in his right eye. On presentation, his visual acuity was 20/60 and intraocular pressure was 48 mm Hg OD. He underwent GATT and cataract phacoemulsification. Following 22 months of follow-up, the patient's visual acuity was 20/30 and intraocular pressure 13 mm Hg, off all glaucoma medications. This case demonstrates GATT may be a good surgical option for post-PKP glaucoma, given the ability to perform future incisional surgery and avoidance of high-risk complications associated with traditional glaucoma surgeries.

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.
