Abstract

fetched live from OpenAlex

Introduction: Pituitary adenomas are benign tumours that can lead to visual loss through compression of the optic chiasm. Patients with pituitary adenomas often present with visual field defects (commonly bitemporal hemianopia), but some may be asymptomatic. In such cases, abnormalities may only be detected through visual field testing or optical coherence tomography (OCT) of the ganglion cell-inner plexiform layer (GCIPL), which may provide a more sensitive method for detecting such abnormalities. Case Presentation: A 72-year-old man was incidentally found to have binasal OCT-GCIPL thinning during a routine eye examination. Visual acuity was 20/20 in both eyes. Pupils were equal and reactive without a relative afferent pupillary defect. His Humphrey 24-2 SITA-Fast visual field test results were normal. A magnetic resonance imaging (MRI) revealed a nonenhancing (cystic) sellar/suprasellar mass measuring 1.7 cm craniocaudal by 2.1 cm anteroposteriorly, without associated optic chiasm compression. The lesion was suspected to be either a cystic pituitary adenoma or a Rathke's cleft cyst. Follow-up examination 1 year later showed all findings remained stable, including an unchanged visual acuity, visual fields, OCT-GCIPL, and MRI. Conclusion: The binasal thinning observed on OCT-GCIPL in this case, despite the absence of chiasmal compression on MRI, is suggestive of previous compression of the optic chiasm. This case highlights the potential for spontaneous regression of pituitary adenomas and underscores the importance of OCT-GCIPL as a vital tool for detecting optic chiasmal damage.

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.
