Amsler-Verrey sign during cataract surgery in Fuchs heterochromic uveitis
Bibliographic record
Abstract
Fuchs heterochromic uveitis (FHU) in its classic presentation is a unilateral, chronic, low grade, often asymptomatic anterior uveitis. It is characterized by a classic triad of iris heterochromia, cataract and keratic precipitates. Neovascularization of the iris and the anterior chamber (AC) angle (radial and circumferential) occurs in 6-22% of cases. This angle and iris new vessels can sometimes lead to a characteristic filiform haemorrhage and formation of hyphaema after AC paracentesis and is a hallmark of FHU known as Amsler-Verrey sign. This haemorrhage has been previously associated with trivial trauma, mydriasis, applanation tonometry, gonioscopy, or it may occur spontaneously. In the setting of cataract surgery it has been previously reported with the use of a Honan balloon. We report a case of cataract and FHU where the Amsler-Verrey sign developed intraoperatively during a phacoemulsification procedure. To the best of our knowledge, this is the first documented report of this sign occurring intraoperatively during cataract surgery.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 2 models reading the full record.
