Nonarteritic Anterior Ischemic Optic Neuropathy following Herpes Zoster Ophthalmicus and Steroid-Related Intraocular Pressure Spike
Bibliographic record
Abstract
A 61-year-old woman presented with sudden vision loss from a left anterior optic neuropathy in the context of severely elevated intraocular pressure after starting topical steroids for anterior uveitis related to herpes zoster ophthalmicus (HZO). The strong temporal relationship between the vision loss and elevated IOP suggested the vision loss was related to nonarteritic anterior ischemic optic neuropathy (NAION). Anterior chamber paracentesis did not detect varicella zoster virus (VZV) and magnetic resonance imaging of the orbits was normal. Her vision remained stable and the optic disc edema resolved within 3 months. The occurrence of NAION following an acute elevation of intraocular pressure (IOP) is well-documented in the context of surgical procedures, glaucoma, uveitis and trauma. This case indicates that not every optic neuropathy in close temporal relationship with HZO is directly attributable to the virus. NAION may also occur after steroid-related IOP spikes and ophthalmologists should ensure that patients on topical steroids are closely monitored for ocular complications.

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.
