OBJECTIVE : To propose a new technique of a double inverted epiretinal membrane (ERM) and internal limiting membrane (ILM) flap (double flap group) for the treatment of idiopathic lamellar macular hole (LMH) with atypical ERM (AERM) and to compare surgical outcomes to those of the standard technique of ERM and ILM peeling of the fovea including LMH (control group). METHODS : AERM was tomographically defined as a medium reflective thickened membrane above the retinal fiber layers without retinal traction signs. A series of patients affected by LMH with AERM were recruited. Preoperative parameters were: intraretinal cysts (IRC), intraretinal splitting diameter, residual foveal thickness, and ellipsoid zone integrity. Postoperative findings were: full-thickness macular hole (FTMH) development, and persistence or new appearance of IRC. Best-corrected visual acuity (BCVA) at baseline, first, third, and sixth postoperative month was evaluated. RESULTS : A total of 48 eyes of 48 patients were included in this study. In the double flap group (30 eyes), a clear improvement of BCVA was noted (p = 0.004), and there were no complications. In the control group (18 eyes), BCVA did not improve and 3 patients developed postoperative FTMH. CONCLUSIONS : The double inverted flap technique is associated with better functional recovery compared to the standard technique and reduces the risk of postoperative FTMH development.
