Children aged ≤ 16 years with OGI based on the Birmingham Eye Trauma Terminology classification were included. The age, gender, type, cause of OGI, and vision were recorded, as well as uncorrected and best corrected visual acuity (UCVA and BCVA, respectively). There was a change in the UCVA and BCVA one year after management. BCVA following management was linked to a variety of factors.Results: There were 664 eyes with OGI. [median age 5.1, 461 (69.6%) boys]. UCVA at presentation was < 20/400 in 525 (79%) of eyes with OGI. Injuries were mainly due to metallic objects in 195 (29.4%), glass in 102 (15.4%), and fireworks in 62 (9.4%). The Change in visual impairment grade in UCVA and BCVA after management compared to the initial presentation was significant (p < 0.001). Improvement of two lines of BCVA was noted in 345 (52%), no change in (

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.
