Summary
The inverted multi-layer internal limiting membrane (ILM) flap technique shows superior anatomical outcomes for macular hole retinal detachment in high myopia compared to standard ILM peeling. Functional outcomes were similar between the two surgical methods.
Area of Science:
- Ophthalmology
- Retinal Surgery
- High Myopia Research
Background:
- Macular hole retinal detachment (MHRD) in high myopia presents unique surgical challenges.
- Pars plana vitrectomy (PPV) is a standard treatment, but achieving optimal outcomes requires innovative techniques.
- Internal limiting membrane (ILM) manipulation is crucial for successful MHRD repair.
Purpose of the Study:
- To compare the surgical outcomes of PPV combined with an inverted multi-layer ILM flap versus standard ILM peeling for MHRD in high myopia.
- To evaluate differences in retinal reattachment, macular hole closure, and best-corrected visual acuity (BCVA) between the two surgical techniques.
Main Methods:
- Retrospective analysis of medical records for high myopia patients with MHRD.
- Two surgical groups: inverted multi-layer ILM flap (Group 1, 27 eyes) and ILM peeling (Group 2, 29 eyes).
- Comparison of retinal reattachment rate, macular hole closure rate, and BCVA at 6 months post-operation.
Main Results:
- Retinal reattachment rates were high and not significantly different (96.3% vs. 93.1%).
- Macular hole closure was significantly better with the inverted ILM flap technique (100% Type I closure vs. 24.1% Type I closure).
- Both groups showed significant BCVA improvement, with no significant difference between groups post-operation.
Conclusions:
- The inverted multi-layer ILM flap technique offers superior anatomical success for MHRD in high myopia.
- While functional outcomes (BCVA) were comparable, the flap technique enhances macular hole closure rates.
- This technique represents a promising advancement for managing complex MHRD cases in high myopia.
