Comparison of Two Different Techniques in Macular Hole Surgery: 12-month Results of Clinical Practice

OpenAlex English

Objective: To examine and compare the outcomes of the complete internal limiting membrane (ILM) peeling and inverted ILM flap techniques in subjects with idiopathic full-thickness macular holes.Methods: 16 eyes of 16 patients operated on with standard complete ILM peeling technique were included in group 1 and 12 eyes of 12 patients that had vitrectomy with inverted ILM flap technique were included in group 2. Baseline and postoperative month 3, month 6, and month 12 best-corrected visual acuity (BCVA) data and spectral-domain optical coherence tomography (SD-OCT) images were examined.Macular hole closure, foveal contour formation, ellipsoid zone (EZ) integrity on OCT images, and improvement in BCVA were analyzed.Results: Macular hole closure rate was 62.5% in group 1 and 91.7% in group 2 but the difference between the groups was not significant (p=0.18).An improvement was seen in BCVA after surgery in group 1 but the difference was not significant when compared with the preoperative BCVA (p=0.28).In group 2, the improvement from baseline BCVA at postoperative month 12 was significant (p=0.016).Conclusion: Macular hole closure rate was over 90% in the eyes that were operated on with the inverted ILM flap technique.BCVA was improved after surgery in both groups and a significant improvement from baseline BCVA was seen at postoperative month 12 with the inverted ILM flap technique.
