NONARTERITIC ANTERIOR ISCHEMIC OPTIC NEUROPATHY AFTER INTRAVITREAL AFLIBERCEPT FOR AGE-RELATED MACULAR DEGENERATION
Bibliographic record
Abstract
PURPOSE: To report a case of nonarteritic anterior ischemic optic neuropathy (NAION) after intravitreal injection in a patient with a history of fellow-eye NAION. METHODS: Observational case report. RESULTS: An 82-year-old woman with a history of fellow eye NAION developed an inferior visual field defect 1 day after an intravitreal aflibercept injection for neovascular age-related macular degeneration. She was found to have optic disk edema and an inferior altitudinal defect, consistent with NAION. The mechanism may have involved compromised perfusion to the optic nerve head related to elevated intraocular pressure or vasoconstriction because of antivascular endothelial growth factor activity. CONCLUSION: Nonarteritic anterior ischemic optic neuropathy is a rare complication of intravitreal injection and may be related to postinjection elevation in intraocular pressure. Monitoring of intraocular pressure postinjection with low-threshold for preinjection aqueous suppression or postinjection anterior chamber paracentesis for persistently elevated intraocular pressure is recommended in patients with a history of NAION.

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.
