Recent advances in macular hole surgery have significantly improved the rates of anatomical success. One important advance is the dye-assisted peeling of the internal limiting membrane (ILM) around the hole. In large holes (<400 μ), sometimes, ILM peeling alone is not enough to achieve closure, and this may be improved by inverting part of the peeled membrane and using it to cover the macular hole or inverting and tucking the ILM flap into the hole. In this case report, a patient with large full-thickness macular hole underwent a hole repair with an inverted ILM flap technique. The eye developed a subsequent retinal detachment with large collection of subretinal fluid beneath the repaired hole, but the hole remained intact, suggesting that the adhesive forces binding an inverted flap to the edges of a repaired macular hole appear to be strong enough to maintain structural integrity of the closed hole even in the presence of a macula-involving retinal detachment with large subretinal fluid collection.
