Abstract

fetched live from OpenAlex

PURPOSE: To report the posterior segment and retinal vascular manifestations of calcific uremic arteriolopathy (calciphylaxis). Clinical findings are correlated with multimodal imaging results. METHODS: Observational case report. RESULTS: A 65-year-old white woman on hemodialysis was referred for assessment of poor vision bilaterally. Clinical examination demonstrated a crystalline retinopathy with stigma of previous retinal arterial occlusion. Fluorescein angiography revealed delayed retinal arterial filling bilaterally, sheathing of vessels, and peripheral nonperfusion. The crystals were hyperautofluorescent. Spectral domain and enhanced depth imaging optical coherence tomography localized the crystals within the retina with a predilection for the retinal arterial vasculature. The choriocapillaris was not involved. Two years prior, the patient developed necrotic skin lesions which were biopsied and confirmed the diagnosis of calciphylaxis. CONCLUSION: Calcific uremic arteriolopathy is an extremely rare cause of thrombogenic microangiopathy in end-stage renal disease patients. Retinal arterial occlusion appears to be a rare but significant cause of visual loss in this disease and is likely to be consequent to crystalline deposition in the retinal vasculature.

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.
