Abstract
Assessment of the red reflex is absolutely fundamental and should be performed as soon as possible after birth. This is best done in a dimly lit room using a direct ophthalmoscope set at +4 diopters at a working distance of 30.48 cm to 45.72 cm (12 inches to 18 inches) to illuminate both pupils simultaneously (Figure 1). The reflex should be identical in each eye and any difference found is cause for immediate referral. Assessment in heavily pigmented infants may be difficult, in which case the pupils can be dilated with 2.5% phenylephrine drops (Mydfrin [Alcon, USA]) instilled twice, 5 min apart. Parents may also be instructed to photograph their babies in a dimly lit room with the red eye reduction feature of the camera turned off, and to report any differences immediately. Figure 1) Assessment of the red reflex in the operating room showing retinoblastoma The reason that timing is so crucial is that the window of opportunity to treat infants all but closes at three months of age. If the visual axis has not been cleared and optical rehabilitation begun by this age, irreversible deprivational amblyopia occurs in the visual pathways and cortex, dooming salvage of useful vision to failure. The following are some threatening conditions.

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.
