Ophthalmological Features of Machado-Joseph Disease.
Bibliographic record
Abstract
Machado-Joseph disease (MJD) or spinocerebellar ataxia type-3 (SCA3) is a rare and progressive neurodegenerative disorder, as well as the most frequently inherited spinocerebellar ataxia. It has extensive polymorphic features, described through a spectrum of neurological, and especially, ophthalmological manifestations. Besides the deterioration of the oculomotor systems, degeneration predominantly involves the cerebellar, pyramidal, extra-pyramidal, and peripheral motor systems. Few patients express Parkinsonian features as well. Through two separate cases, we present the major differences seen in the two patients, but also display their underlying similarities in the context of MJD; specifically, the ophthalmological features. The shared features include nystagmus in the horizontal direction, orbicularis oculi contractions, and bilateral esotropia. The findings indicate the importance of the inherent ophthalmological features expressed in MJD.

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.
