An Infected Porous Polyethylene Orbital Implant
Bibliographic record
Abstract
In Brief A 75-year-old man underwent enucleation with placement of a porous polyethylene orbital implant (Medpor, Porex Technologies, Fairburn, GA, U.S.A.). Over the next 5 years, he was seen on numerous occasions with socket discharge that was unresponsive to a variety of eyedrops. Exposure and re-exposure of the implant occurred, and the implant was removed. Histopathologic assessment was consistent with an infectious process within the implant. Postoperatively, the patient’s symptoms and signs resolved. Porous orbital implant infection is rare. The diagnosis may be delayed as the initial symptoms and signs (discharge, conjunctival inflammation) may easily be attributed to prosthesis wear. With time, and persistence of the symptoms despite numerous treatments, infection should be suspected. While rare, implant infection should be suspected in patients with porous orbital implants who experience persistent, recalcitrant ocular discharge and conjunctival inflammation.

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.
