Abstract
In spite of established indications for early operative repair of orbital floor fractures 7-10% of patients treated nonoperatively develop enophthalmos. Clearly further indications for repair are required to prevent these post-injury complications. Rounding of the inferior rectus muscle on coronal computerized tomography (CT) scan results from a loss of soft tissue and bony support and may therefore be predictive of late enophthalmos.A four-year institutional review was conducted to identify patients with orbital floor fractures that had been treated nonoperatively. Patients were recruited for late clinical follow-up (mean 30 months) where clinically significant enophthalmos and diplopia were measured. Clinical results were correlated with measurements of the height-to-width ratio of the inferior rectus muscle on CT scans by a blinded examiner. Eighteen of 78 patients were available for late follow-up. Sixteen patients had no enophthalmos whereas 2 patients had enophthalmos. The inferior rectus height-to-width ratios measured in the unaffected orbits were statistically similar between the two groups. There was a significantly increased height-to-width ratio exceeding 1.00 in the affected orbit when the enophthalmos group was compared to the no enophthalmos group.A height-to-width ratio of the inferior rectus muscle on coronal CT scan of greater than or equal to 1.00 is predictive of late enophthalmos.

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
