An Uncommon Presentation of Pigmented Paravenous Retinochoroidal Atrophy
Bibliographic record
Abstract
Pigmented paravenous retinochoroidal atrophy is a rare diagnosis of exclusion as it can mimic many hereditary retinal (namely retinitis pigmentosa), infectious, and inflammatory disorders. Once diagnosed, it carries a favorable prognosis due to the macula being spared with slow to no progression and lack of symptoms. However, rare cases have noted macula involvement and symptoms including nyctalopia. Clinicians should be aware of presentations of pigmented paravenous retinochoroidal atrophy, beyond the typical findings noted in the literature, as these cases could be misdiagnosed. This case presents a rare presentation of pigmented paravenous retinochoroidal atrophy. A review of common and uncommon findings, potential pathophysiology, differential diagnoses, and multimodal imaging results is also presented.

How this classification was reachedexpand
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.
