Abstract
BACKGROUND: With the increasing popularity of three dimensional filler treatments, the tip of the injecting needle or cannula is subdermal, often adjacent to the facial vasculature. Inadvertent canalization of these vessels can rarely result in vascular occlusion with consequent blindness or stroke. OBJECTIVE: The goal was to demonstrate a technique of retro or peribulbar injection of hyaluronidase should such an emergency arise if no ophthalmologist was immediately available. The treatment is needed urgently because the retina can only withstand up to 90 minutes of hypoxia. MATERIALS AND METHODS: We present verbal and diagrammatic instructions for this treatment and videos of both the retrobulbar technique (courtesy of Dr. D. Maberley) and peribulbar technique (courtesy of Dr. S. Fagien). RESULTS: None of us have yet used this technique to treat iatrogenic filler induced blindness but we present the information for the benefit of patient safety, given the limited time the retina can survive vascular occlusion. CONCLUSION: Inadvertent canalization of facial vessels can cause embolic occlusion of retinal vasculature because of the anastomotic nature of the facial vasculature and the end artery morphology of the retinal circulation. Embolism from 3-dimensional hyaluronic acid filler use is potentially reversible if hyaluronidase is injected into the adjacent tissue.

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
