Abstract

fetched live from OpenAlex

BACKGROUND: Optic nerve compression from direct contact with the internal carotid artery (ICA) is a rarely described cause of monocular vision loss. Thus, little is known about the incidence, optimal management, and outcomes of this particular type of compressive optic neuropathy. OBSERVATIONS: The authors present the case of a 52-year-old female with progressive monocular vision loss. After an extensive workup, including a formal neuro-ophthalmology assessment, her symptoms were attributed to a neurovascular conflict between the optic nerve and a nonectatic supraclinoid ICA. She underwent a pterional craniotomy for optic nerve decompression, including bony unroofing of the optic canal and fenestration of the dural sheath. On follow-up, there was improvement in both her radiographic and clinical findings. LESSONS: This case highlights a unique indication for optic nerve decompression in the setting of monocular vision loss caused by nonectatic vascular compression. https://thejns.org/doi/10.3171/CASE24623.

Full frame distilled prediction

Teacher imitation

Not 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.
