Prone posturing after macular hole surgery (MHS) offers no anatomic or visual benefit. However, avoiding posturing may accelerate cataract development, suggesting combined surgery might be beneficial.

Area of Science:

  • Ophthalmology
  • Retinal Surgery

Background:

  • Macular hole surgery (MHS) is a common procedure to restore vision.
  • Postoperative positioning, particularly prone posturing, is often recommended to improve outcomes.
  • The necessity and impact of prone posturing in MHS require further investigation.

Purpose of the Study:

  • To evaluate the role of vitrectomy without prone posturing in the anatomical and functional results of MHS.
  • To compare outcomes between patients who underwent prone posturing and those who did not.

Main Methods:

  • A study involving 41 patients with full-thickness macular holes (stage II-IV).
  • All patients underwent pars plana vitrectomy with 16% C3F8 tamponade.
  • Patients were divided into a posturing group (n=25) and a non-posturing group (n=16), with different positioning instructions.

Main Results:

  • Anatomical hole closure rates were similar in both groups (88% vs. 87.5%).
  • No significant differences were observed in visual acuity, contrast sensitivity, metamorphopsia, or visual function scores between the groups.
  • The non-posturing group experienced significantly more severe early postoperative cataract development.

Conclusions:

  • Prone posturing following MHS does not provide additional functional or anatomical benefits.
  • Avoiding prone posturing is associated with a faster progression of cataract.
  • Combined phacovitrectomy without face-down positioning may be a viable option for phakic patients undergoing MHS.
