Pallid optic disc oedema in non-arteritic anterior ischaemic optic neuropathy without a conventional ‘disc at risk’
Bibliographic record
Abstract
Non-arteritic anterior ischaemic optic neuropathy (NAION) is typically characterised by non-pallid optic disc oedema and a contralateral small optic nerve head. Typically, the optic cup is absent or small with a cup-to-disc ratio of less than 0.3 termed 'disc at risk'. While systemic and ocular risk factors are identified as risk factors of NAION, the exact pathogenesis of NAION is not fully understood. We report a case of NAION with pallid optic disc oedema and the absence of a disc at risk in a patient with multiple vascular risk factors, suggesting an underlying severe atherosclerotic pathology. This case highlights that NAION may present with atypical features with pallid optic disc oedema and absence of a disc at risk and highlights atherosclerosis as an associated underlying risk factor.

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.
