NOVEL SURGICAL TECHNIQUE TO REMOVE RETAINED SUBFOVEAL PERFLUOROCARBON LIQUID
Bibliographic record
Abstract
PURPOSE: To describe a novel surgical technique to remove retained subfoveal perfluorocarbon liquid (PFCL). METHODS: After setting up for 23-G pars plana vitrectomy, a 38-G flexible-tip macular hydrodissection cannula connected to the automated viscous fluid infusion kit was used to create a small retinotomy approximately 700 μm to 800 μm inferior to the fovea and induce macular detachment involving the retained PFCL bubble. The flexible cannula was bent at its junction with the shaft and was carefully advanced through the same retinotomy into the subretinal space to access and directly aspirate the retained subfoveal PFCL bubble. Fluid-air exchange was then performed, and surgery was concluded. RESULTS: The retained subfoveal PFCL bubble was successfully removed with restoration of normal foveal architecture on optical coherence tomography and with objective and subjective improvement of central vision. CONCLUSION: We report a novel surgical technique combining macular detachment with direct aspiration of the retained subfoveal PFCL without direct perforation of the foveal center. This technique may provide an alternative approach to manage this difficult complication.

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.
