Abstract
Abstract Central retinal vein occlusion (CRVO) secondary to severe acute respiratory syndrome coronavirus 2–induced coagulation abnormalities is rare. A 32-year-old man presented with bilateral CRVO. He had a history of retinal migraine with occasional floaters and received 2 primary and a booster dose of the BNT162b2 vaccine 7 months prior. Four months before presentation, he developed acute blurring of vision in the left eye and was diagnosed with a nonischemic CRVO with dot-blot hemorrhages. He was managed conservatively with aspirin. Three weeks later, he contracted COVID-19 and received 5 days of nirmatrelvir/ritonavir. Four weeks after his COVID infection, repeat fundoscopic evaluation demonstrated resolving hemorrhages in the left eye but a new CRVO in the right eye. Antivascular endothelial growth factor injections were deferred because of normal visual acuity. He had a normal magnetic resonance imaging of the brain and a normal bilateral carotid duplex and was planned for close follow-up with ophthalmology. COVID-19 patients presenting with visual symptoms should be screened for CRVO.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
