Abuse of Vasoconstrictive Eyedrops Mimicking an Ocular Pemphigoid
Bibliographic record
Abstract
PURPOSE: To describe conjunctival histopathologic alterations induced by excessive chronic astringent use. METHODS: Report of a case with clinical picture, epicutane test results, histologic workup of conjunctival biopsy using conventional staining, and immunohistochemical markers. RESULTS: A 45-year-old man using a phenylephrine preparation hourly for years presented with grotesque eye redness, fornix shortening, and scarring of puncta lacrimalia. Direct and indirect immunofluorescence were negative for ocular pemphigoid. Histology revealed signs of chronic inflammation and neovascularization in the conjunctiva. Symptoms resolved after cessation of therapy. CONCLUSIONS: Chronic abuse of decongestant eyedrops can produce a clinical picture resembling an ocular pemphigoid. Histology suggests that late onset immunoreaction and chronic vasoconstriction cause chronic inflammation and neovascularization, respectively.

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.
