Effect of Facedown vs Non-Facedown Position on Macular Hole Closure after Surgery

Background: Internal Limiting Membrane (ILM) peeling with Gas tamponade after Pars Plana vitrectomy is routinely done in macular hole surgery. After the procedure, a face-down position (FDP) advised to patients promote closure by pushing bubble of against posterior pole. However, elderly and those medical comorbidities may feel uncomfortable FDP. A few post-operative complications also be caused it. So, aim this study compare evaluate role postoperative non-face-down (nFDP) FDP on rate PPV ILM peeling. Patients methods: 20 phakic eyes patients, idiopathic full-thickness holes, underwent vitrectomy, dye-assisted 14% perfluoro propane gas. were divided randomly into two groups; face down (FDP, posturing group) or non (nFDP, non-posturing for 7 days. Main focus was see anatomical till days postoperatively. Results: Macular holes closed 10 group 9 out seven Chi-square test applied association between / without position. It observed that less likely associated (X2= 1.2, p-value= 0.549) while it size 15.9, 0.001). In sub-group analysis according size, all smaller than 490 µm regardless posturing. While larger not nFDP Conclusion: Post-operative has no statistically significant effect comparison non-face positioning.
