Abstract
Purpose: To evaluate the efficacy of inverted internal limiting membrane (ILM) technique for large macular holes (MHs) (> 400 μm) and to compare the anatomical and functional outcomes with the standard technique.
Material and Methods: Comparative prospective study on 70 cases separated into two groups, group 1 of 39 patients were operated with ILM peeling and in group 2, 31 eyes underwent a modification of the standard technique, called the inverted internal limiting membrane (ILM) flap technique.
Results: The mean age of patients was 60.4 years. Mean postoperative BCVA, patients in both groups showed a statistically significant improvement in visual acuity (p:0.37). The closure rate of macular hole was 98%. The diameter of macular holes varied between 400 - 1100 μm. DONFL were observed in 10 patients in group 1 versus 7 patients in group 2.
Conclusion: We observed that visual acuity improvement rate after reverse ILM technique was higher but the anatomical outcome for large MH was achieved using both techniques.
