ANATOMICAL AND VISUAL OUTCOMES OF MACULAR HOLE SURGERY WITH SHORT-DURATION 3-DAY FACE-DOWN POSITIONING
Bibliographic record
Abstract
In Brief Purpose: The role of face-down posturing after macular hole (MH) surgery remains unclear and controversial. We evaluated the anatomical and visual outcomes of MH repair using a short duration (3 days) of prone positioning. Methods: Prospective series of 50 consecutive eyes in 50 patients with Stage 2 or Stage 3 idiopathic MHs. All eyes underwent vitrectomy MH surgery with internal limiting membrane peeling and 20% sulfur hexafluoride (SF6) gas tamponade. The procedure was combined with phacoemulsification cataract surgery in phakic eyes. Surgical outcomes, MH closure rates, complications, and postoperative visual acuity were investigated. Results: Anatomical closure of MHs was achieved in 49 (98%) of 50 eyes by 1 surgery. Postoperative logarithm of the minimum angle of resolution visual acuity decreased (i.e., improved) by 0.271 (95% confidence interval, 0.101–0.441 [P = 0.0024]). One complication of intraocular lens pupillary capture and one case of chronic cystoid macular edema were observed. There were no complications attributed to intraocular pressure fluctuations. Conclusion: Vitrectomy with internal limiting membrane peeling and gas tamponade with SF6 followed by short-duration 3-day face-down positioning is a successful surgical intervention for Stage 2 and Stage 3 idiopathic MHs. This method possessed minimal complications and offered significant improvement in visual acuity. An interventional prospective series of 50 consecutive eyes with idiopathic macular holes underwent vitrectomy with internal limiting membrane peeling and gas tamponade followed by short-duration 3-days face-down positioning. Successful anatomical closure was achieved in 98% of eyes by 1 surgery with minimal complications and significant improvement in visual acuity.

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.
