Abstract

fetched live from OpenAlex

Purpose: To report on the diagnostic and therapeutic approach in a patient with retinitis pigmentosa (RP), hypovitaminoses, and bilateral corneal involvement. Case Report: A 62-year-old woman, diagnosed with RP, presented with photophobia, sudden bilateral visual decline, and known long-term night blindness. Ophthalmic examination showed corneal perforation in the right eye, corneal ulcer in the left eye, and bilateral corneal hypoesthesia. She had undergone bariatric surgery and recently suspended vitamin supplementation. Blood tests revealed hypovitaminoses A, D, D3, and E. The patient underwent tectonic keratoplasty in the right eye and received topical therapy in the left eye, and then restarted vitamin supplementation as recommended by the nutritionist. Significant functional recovery was documented in both eyes at 1-, 3-, and 10-month follow-ups. Conclusion: The case highlights the importance of an integrative approach that includes comprehensive history taking, targeted laboratory work-up, as well as accurate differential diagnosis, especially given the potential multifactorality of ocular symptoms and signs.

Teacher imitation

Not 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.
