Abstract

fetched live from OpenAlex

BackgroundCorneal ulcers are typically caused by external ("exogenous") factors such as trauma, contact lens use, or preexisting ocular surface diseases. Internal systemic ("endogenous") sources have not been reported as direct causes of corneal ulcers. Here, we report, to our knowledge, the first documented case of a corneoscleral abscess that resulted from an underlying bacteremia.MethodThis is a single case report.ResultA previously healthy 35-year-old male presented to the Emergency Department with left eye redness, pain, and blurred vision. Initial examination showed reduced visual acuity (20/150), elevated intraocular pressure (44mmHg), diffuse microcystic corneal edema with mutton-fat keratic precipitates, and anterior chamber cells. No corneal infiltrate, epithelial defect, hypopyon, or vitritis was noted. Within days, his condition rapidly progressed to a corneoscleral abscess with auto-evisceration. Blood and corneal cultures identified hypermucoviscous Klebsiella pneumoniae. Further workup revealed an underlying prostatic abscess with secondary iliac vein thrombus, leading to seeding of other sites, including the lungs and the eye. Despite intensive antibiotic therapy, the ocular condition worsened, requiring urgent left eye evisceration.ConclusionThis case highlights the rapid progression of hypermucoviscous Klebsiella pneumoniae infection, which first presented with endophthalmitis, followed by corneoscleral perforation.

Full frame distilled prediction

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.
