An atypical case of HLA-B27-associated uveitis with hypopyon and posterior segment involvement
Bibliographic record
Abstract
The presence of a hypopyon and posterior segment involvement are uncommon clinical findings in HLA-B27-associated uveitis. Furthermore, first-time attacks rarely occur in the elderly. This report highlights an atypical uveitis case involving an older patient, an evident hypopyon and severe intermediate uveitis in one eye. The 60-year-old Caucasian male was admitted for a painful, red eye with a sudden decreased vision to hand motion, in the affected eye. Ocular and systemic history were unremarkable. An anterior chamber examination of the eye revealed extensive cells and flare with a conspicuous hypopyon. An evaluation of the posterior segment revealed significant vitreous haze, obstructing all view to the retina. Despite the age and the atypical ocular findings of the patient, a diagnosis of HLA-B27-associated uveitis was made following an extensive clinical and laboratory evaluation. The inflammatory condition was successfully managed with a combination of intravenous, topical and oral corticosteroids tapered over the course of a few weeks, and visual acuity recovered to 20/30. This case is an important reminder that atypical signs, such as a hypopyon or intermediate uveitis, can occur and may be a significant sign of HLA-B27-associated uveitis. Clinicians should be aware of the diverse manifestations of HLA-B27-associated uveitis and be careful to include a comprehensive assessment of both the anterior and posterior segments of any presenting painful, red eye.

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.
