Summary
Peeling the internal limiting membrane (ILM) during macular hole surgery is not essential for success. However, excessive ILM peeling may reduce visual outcomes, suggesting a need for refined surgical techniques.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Microsurgery
Background:
- Epiretinal membranes (ERMs) can affect visual acuity.
- Macular hole surgery aims to restore retinal anatomy and visual function.
- The role of internal limiting membrane (ILM) peeling in achieving surgical success is debated.
Purpose of the Study:
- To prospectively evaluate the impact of epiretinal membrane peeling on macular hole surgery outcomes.
- To correlate the extent of ILM peeling with anatomic success and visual acuity improvements.
Main Methods:
- Prospective, interventional case series involving 193 patients undergoing macular hole surgery.
- Intraoperative assessment of ERM peeling extent and correlation with surgical endpoints.
- Evaluation of anatomic success (hole closure), visual acuity (20/50 or better), and visual improvement (≥2 Snellen lines).
Main Results:
- Overall anatomic success rate was 93% with a minimum 6-week follow-up.
- Significant visual improvement (≥2 lines) achieved in 72%; 56% attained 20/50 or better acuity.
- ILM peeling extent was inversely correlated with anatomic success (P=0.045) and correlated with final visual acuity.
Conclusions:
- ILM peeling is not strictly necessary for achieving anatomic or visual success in macular hole surgery.
- Excessive or unsuccessful ILM peeling attempts may negatively impact visual outcomes.
- Further research into reproducible, atraumatic ILM peeling techniques is warranted.
