Summary
Reducing internal limiting membrane (ILM) peeling in macular hole surgery is effective. The temporal inverted ILM flap technique provides satisfactory outcomes for large Stage IV idiopathic macular holes.
Area of Science:
- Ophthalmology
- Retinal Surgery
Background:
- Large Stage IV idiopathic macular holes present significant surgical challenges.
- The inverted internal limiting membrane (ILM) flap technique is a common surgical approach.
- Optimizing ILM peeling is crucial for successful macular hole repair.
Purpose of the Study:
- To evaluate the efficacy of a modified inverted ILM flap technique with reduced ILM peeling for large Stage IV idiopathic macular holes.
- To compare the outcomes of the classic inverted ILM flap technique versus a temporal inverted ILM flap technique.
Main Methods:
- Prospective comparative interventional study involving 87 eyes.
- Patients were randomized into two groups: classic inverted ILM flap (Group A) and temporal inverted ILM flap (Group B).
- The modified technique restricted ILM peeling to the temporal side of the fovea.
Main Results:
- No significant difference in initial and final visual acuities between the two groups.
- Both techniques showed a decrease in photoreceptor and external limiting membrane defects over time.
- The modified technique (temporal inverted ILM flap) showed a less frequent incidence of dissociated optic nerve fiber layer appearance postoperatively.
Conclusions:
- The temporal inverted ILM flap technique is a viable and effective alternative for repairing large Stage IV idiopathic macular holes.
- Reducing the extent of ILM peeling may offer comparable visual outcomes with potentially fewer complications.
- This modified approach demonstrates non-inferiority to the classic technique.
