简要总结
This is a prospective, multicenter, randomized non-inferiority trial, where the macular hole closure rate with intraocular air tamponade is compared to the closure rate with gas tamponade.The patients are randomized to receive either air or gas (26% SF6) as intraocular tamponade, just prior to the intraocular flushing of the tamponade during the vitrectomy procedure. Postoperatively, the patients adhere to the nonsupine regimen for three days, and the tennis ball technique is used during sleep to enhance patients' positioning compliance.
