Internal Plugging of a Traumatic Posterior Perforation Site Using Donor Sclera, Human Amniotic Membrane, and Fibrin Glue: A Novel Surgical Technique
Bibliographic record
Abstract
Purpose: To describe a novel surgical approach to treat traumatic posterior perforating injuries. Methods: A case and its findings were analyzed. Results: A 21-year-old man presented with bilateral intraocular foreign bodies that were sustained while hammering a metal railway pin. In the left eye, the foreign body was embedded in the posterior scleral wall, resulting in a 2 mm × 6 mm posterior perforation and partial retinal detachment. Silicone oil tamponade could optimize the chances for retinal reattachment; however, there was concern that the silicone oil would migrate through the posterior defect and into the orbit. Therefore, the perforation site was filled using a 3-layer plug consisting of donor sclera, human amniotic membrane, and fibrin glue. The silicone oil was successfully maintained within the globe; however, the final visual acuity was limited due to proliferative vitreoretinopathy. Conclusions: The efficacy and safety of the 3-layer plug technique should be further validated in similar cases.

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.
