Successful Corneal Autograft After Clearance of Anterior Chamber Cytomegalovirus With Oral Valganciclovir in a Patient With Multiple Failed Corneal Allografts
Bibliographic record
Abstract
PURPOSE: To report a case of recurrent corneal graft failure because of cytomegalovirus (CMV) infection and to demonstrate successful clearance of the virus with oral valganciclovir, confirmed by polymerase chain reaction (PCR) assay. This allowed for a successful corneal autograft to be performed. METHODS: Interventional case report. RESULTS: A 90-year-old white man with 4 previous corneal graft failures in his right eye is presented. His visual acuity was no light perception in the left eye subsequent to ocular trauma. His initial penetrating keratoplasty for pseudophakic bullous keratopathy was from a human leukocyte antigen-matched multiorgan donor who was CMV-seropositive. An anterior chamber paracentesis was performed to exclude an infective etiology. CMV was detected on PCR of aqueous humor. After a 12-week course of oral valganciclovir, a repeat aqueous PCR test confirmed the clearance of CMV. A corneal autograft from his left eye was subsequently performed with good outcome. CONCLUSIONS: We present a case of successful corneal autograft after clearance of CMV from the anterior chamber (PCR confirmed) in a patient treated with oral valganciclovir.

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.
