Ocular Findings in Raised Intracranial Pressure
Bibliographic record
Abstract
We present the case of a 7-month-old female infant who was found crying and limp. She was transported to a hospital where a possible subarachnoid hemorrhage was diagnosed radiologically. Before further studies could be pursued, her condition worsened and she died. The autopsy demonstrated diffuse subarachnoid hemorrhage of the brain and along the spinal cord. The brain, spinal cord, and eyes were retained and examined postfixation. An aneurysm of the middle cerebral artery was identified. Examination of the eyes demonstrated bilateral optic nerve sheath hemorrhage and extensive retinal hemorrhages extending to the ora serrata. A rapid increase in intracranial pressure secondary to subarachnoid hemorrhage following rupture of an aneurysm can result in sequelae similar to those found in inflicted traumatic brain injury. In this case, the rise in intracranial pressure resulted in marked hemorrhage within the optic nerve sheaths as well as intra- and preretinal hemorrhages. Patients with subarachnoid hemorrhage, or other causes of rapidly increased intracranial pressure, may develop ocular hemorrhage (Terson syndrome). This case illustrates the importance of ruling out natural disease before attributing the autopsy findings to trauma, as well as the importance of postmortem fixation of pediatric brains and eyes prior to examination.

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.
