Abstract

fetched live from OpenAlex

Mitomycin C is an alkylating agent with the ability to suppress fibroblast proliferation and activity, making it a powerful antifibrotic. It has therefore become popular in glaucoma filtering surgeries, used both intraoperatively during bleb formation and postoperatively as an adjunct to bleb needling. This report presents a rare but serious risk of bleb needling with Mitomycin C at the slit lamp, where inadvertent movement of the patient resulted in an orbital injection. The patient quickly developed focal tissue inflammation and necrosis, presenting one day after the procedure with complete ptosis, ophthalmoplegia, and a palpable orbital mass. After appropriate imaging and an excisional biopsy to exclude infectious, infiltrative, and neoplastic causes, this was managed with close observation and continued improvement, and resolution of most orbital sequelae.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
