Summary

Successful macular hole surgery improves vision and photoreceptor integrity. The extent of the inner and outer segment (IS/OS) defect before surgery predicts visual recovery, especially in the parafoveal region.

Area of Science:

  • Ophthalmology
  • Retinal Surgery
  • Vision Science

Background:

  • Macular hole surgery aims to restore visual function.
  • Understanding the correlation between structural and functional recovery is crucial.

Purpose of the Study:

  • To correlate functional and morphological outcomes 12 months after macular hole surgery.
  • To evaluate the regeneration of the photoreceptor inner and outer segment (IS/OS) line.

Main Methods:

  • Prospective study of 16 patients undergoing transconjunctival 23-gauge vitrectomy with ILM peeling.
  • Preoperative and postoperative assessments included best-corrected visual acuity (BCVA), microperimetry (MP-1), and spectral-domain optical coherence tomography (SD-OCT).
  • Evaluation of the IS/OS line integrity and correlation with microperimetry data.

Main Results:

  • Significant improvement in BCVA, macular sensitivity, and fixation was observed 12 months post-surgery.
  • Regeneration of the IS/OS line was noted by 3 months and significant by 12 months.
  • Preoperative IS/OS defect extent, particularly in the parafoveal region, predicted postoperative macular sensitivity.

Conclusions:

  • Successful macular hole surgery leads to correlated morphological and functional improvements.
  • The preoperative IS/OS defect is a predictive parameter for postoperative macular sensitivity.
  • Postoperative visual acuity prediction requires consideration of multiple clinical and anatomical factors.
