Peripheral Ulcerative Keratitis Secondary to Chronic Hepatitis B Infection
Bibliographic record
Abstract
PURPOSE: To report a unique case of peripheral ulcerative keratitis secondary to hepatitis B virus (HBV)-associated cryoglobulinemia and vasculitis and its pharmacological and surgical treatment and 2-year follow-up. METHODS: A 52-year-old woman presented with unilateral eye pain and photophobia, arthralgia, remnants of a maculopapular rash, and subsequently facial numbness several weeks later. Her best spectacle-corrected visual acuity (BSCVA) in the affected eye was 20/80. Slit-lamp examination revealed severe superior corneal thinning without infiltrate. Corneal ulceration worsened until 10% of the cornea remained. Laboratory workup was positive for rheumatoid factor and revealed significantly decreased C4 complement, and HBV serology was positive. RESULTS: Clinical history, examinations, and laboratory results suggest HBV-associated cryoglobulinemia and vasculitis. Management included prednisone, cyclophosphamide, and mycophenolate mofetil for immunosuppression and tenofovir for HBV treatment. Conjunctival resection and a glue patch were used to reduce inflammation and stabilize corneal melt. BSCVA improved after treatment was initiated. Two years after initial presentation, her BSCVA is 20/30, significantly improved from her vision at presentation. CONCLUSIONS: Diagnosis of peripheral ulcerative keratitis requires thorough history and physical examinations given the numerous causes. Prompt treatment including immunosuppressive medication and, in this case, antiviral medication is crucial to preventing serious visual consequences including corneal perforation and blindness.

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.
