Intravascular Papillary Endothelial Hyperplasia as a Cause of Reversible Vision Loss
Bibliographic record
Abstract
ABSTRACT: Intravascular papillary endothelial hyperplasia (IPEH) is a benign vascular lesion that is formally diagnosed on histopathology. IPEH seldom presents in periocular tissues and is even less commonly seen deep within the orbit. As with cavernous hemangioma, this lesion tends to distort surrounding structures and can cause a significant mass effect in the orbit. The authors present an unusual case of orbital IPEH that resulted in severe proptosis and progressive vision loss from optic nerve compression. In toto surgical excision of the lesion resulted in significant recovery of vision loss and resolution of symptoms associated with proptosis. To the best of our knowledge, this case is the first to illustrate the potential for visual recovery after surgery in a patient with compressive optic neuropathy from orbital IPEH.

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.
