Purpose
To investigate the efficacy of modified internal limiting membrane (ILM) flap technique combined with vitreous surgery for treating macular holes and examine the outcomes in visual function and anatomic macular hole closure.
Study Design
Retrospective, observational.
Methods
Between July 1, 2015, and October 1, 2019, the modified inverted ILM flap technique combined with vitreous surgery was used to treat idiopathic macular holes, postoperative progression was then followed for at least 6 months in 96 participants (98 eyes). We modified the method by removing the lower half of the ILM while peeling and inverting the upper half. The mean age of the participants was 65.9 ± 11.9 years (41 men (42.7%) and 55 women (57.3%)). Retrospective evaluations of macular hole diameter, corrected visual acuity, and macular hole closure rates were performed using data from medical records.
Results
The mean macular hole diameter was 623.6 ± 207.4 μm. The mean corrected visual acuity (logMAR) was 0.79 ± 0.27 before surgery and 0.46 ± 0.35 at 1, 0.35 ± 0.39 at 3, and 0.31 ± 0.36 at 6 months Post surgery, showing significant differences before and after surgery (p = 2.30 × 10− 2). The macular hole closure rate was 98%.
Conclusion
The modified inverted ILM flap technique combined with vitreous surgery was an effective method for treating macular holes, resulting in improvement in closure and visual acuity.
