Long anterior lens zonules in late-onset retinal degeneration
Bibliographic record
Abstract
A 64-year-old male was evaluated for a suspected retinal dystrophy. When examined at the slit lamp, long anterior zonules (LAZs) were observed [Fig. 1a]. Posterior segment examination revealed atrophic changes in the posterior pole with corresponding areas of decreased autofluorescence on imaging [Fig. 1b and c]. A clinical diagnosis of late-onset retinal degeneration (L-ORD) was made; genetic testing revealed a pathogenic variant in the C1QTNF5 gene (c.489C>G), which confirmed the diagnosis. LAZs are zonules that extend past the lens equator and are characteristic of L-ORD.[1,2] This finding can manifest early, enabling prompt diagnosis before the development of retinal changes.Figure 1: Long anterior zonules visualized both in slit beam and retroillumination, with zonules extending to the pupillary axis (a).

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.
