Purpose
To assess the effect of an internal limiting membrane flap (IF) in macular hole surgery on best-corrected visual acuity (BCVA) and integrity of the external limiting membrane (ELM) and ellipsoid zone (EZ).
Setting/Venue
Department of Ophthalmology, Hospital rechts der Isar, Technical University of Munich (TUM), Munich, Germany; Department of Ophthalmology, Royal Liverpool University Hospital, Liverpool, UK;
Methods
Patients were included who had successful surgery for macular holes <400 µm with or without an IF. Main outcome measures were BCVA and restoration of the ELM and EZ at 12 months.
Results
Sixty patients were included, 36 with conventional peeling and 24 with an IF. BCVA improved from 0.74 (±0.30) to 0.26 (±0.20) logMAR in patients without and from 0.77 (±0.32) to 0.18 (±0.12) logMAR in patients with an IF, respectively. There was no difference in the integrity of the ELM and EZ in patients with or without an IF at either 3 (p=0.58, p=0.20), 6 (p=0.81, p=0.10), or 12 months (p=0.60, p=0.20) or in the BCVA at 3 (p=0.24), 6 (p=0.18) and 12 months (p=0.11). In the multivariable model, only pre-operative BCVA (p<0.01), EZ integrity (p=0.001), and age (p<0.01) were associated with the post-operative BCVA.
Conlusions
In patients undergoing surgery for macular holes <400 µm, the use of an IF did not affect the BCVA or the integrity of the ELM and EZ.
