Researchers looked back at records of 56 patients who had surgery for large macular holes greater than 400 micrometers. They compared two methods: an inverted internal limiting membrane flap technique versus complete removal of the membrane. The goal was to see which method helped restore vision and specific retinal layers better.
At three months, the flap technique generally showed better results for vision and retinal layer recovery compared to the other method. However, by six months, vision and layer restoration were similar between the two groups for patients with certain hole structures. In other comparisons, the flap technique continued to show superior vision outcomes.
No safety concerns or adverse events were reported in this small group of patients. Because the study only included 56 people and was not a randomized trial, the results are uncertain. Readers should understand that this early evidence does not yet prove one method is definitely better for everyone. Further research is needed to confirm these findings before they change how doctors treat macular holes.
