Abstract
AIMS: To evaluate retinal nerve fiber layer (RNFL) thickness in eyes with Graves' orbitopathy (GO), in eyes with ocular hypertension (OHT) and in a control group of healthy eyes. METHODS: Observational, controlled cross-sectional study. We evaluated all patients with primary open-angle glaucoma (POAG) and all patients with GO and intraocular pressure >23 mm Hg in primary position examined from March 2006 to June 2007. Forty apparently healthy patients (80 eyes) were enrolled as a control group. Complete ophthalmic evaluation, visual field (VF) examination with the Humphrey Visual Field Analyzer and RNFL thickness measurement with optic nerve tracking optical coherence tomography (ONT-OCT; OCT/SLO, OTI, Toronto, Ont., Canada) were performed. RESULTS: Among 116 eyes with POAG [58 patients, 32 males, 26 females, mean age 62 (46-71) years], RNFL was reduced in 87 eyes (75%, p = 0.05) when compared with the control group, and a good correlation was found between RNFL thickness and VF abnormalities (Spearman's rho 0.822; p = 0.001). Among 60 eyes [30 patients, 12 males, 18 females, mean age 56 (50-69) years] with GO and OHT, nonglaucomatous diffuse abnormalities of the VF were detected in 44 eyes (73.3%, p = 0.03), while RNFL thinning was present in 14 eyes (9 patients, 23.3%, p = 0.03). No correlation was found between RNFL thickness and VF abnormalities (Spearman's rho 0.365; p = 0.02). No significant differences in RNFL pattern were present between the group with GO, OHT and RNFL thinning and the group with POAG. CONCLUSIONS: In patients with GO and OHT, evaluation of RNFL thickness with ONT-OCT may represent an objective diagnostic technique for detecting optic neuropathy.

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 it
