Nontraumatic subperiosteal orbital hemorrhage in a laboring patient with gestational immune thrombocytopenic purpura
Bibliographic record
Abstract
PURPOSE: To describe a case of nontraumatic subperiosteal orbital hemorrhage (NTSOH) in a laboring patient with gestational immune thrombocytopenic purpura. OBSERVATIONS: A 28-year-old G3P2 laboring patient was urgently evaluated by our ophthalmology unit after she developed sudden onset left eye proptosis, headache, and diplopia in the final hour of pushing. The patient's platelet count was markedly decreased at 45,000 and subsequent work-up established a diagnosis of gestational immune thrombocytopenic purpura. On examination, visual acuity was 20/25 bilaterally and there was a minus two restriction in upgaze in the left eye and a left hypotropia in primary position. Computed tomography demonstrated an elliptical, hyperdense collection at the left orbital roof consistent with NTSOH. The patient was deemed clinically stable through serial examinations and symptoms resolved with conservative management. CONCLUSIONS AND IMPORTANCE: NTSOH is a rare, potentially sight-threatening condition that requires timely ophthalmological evaluation. To our knowledge, this is the first report in the literature of NTSOH in a laboring patient with gestational immune thrombocytopenic purpura. Consideration of the possibility of NTSOH as a complication in this population may allow for appropriate diagnosis, monitoring, and treatment when indicated.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
