OCT images of two patients who developed full-thickness macular hole postoperatively (A-D) Sixty-six years-old female with an axial length of 26.97 mm had received fovea-sparing internal limiting membrane (ILM) peeling with inverted ILM flap. The preoperative best-corrected visual acuity (BCVA) was 0.52 logMAR and stable at the last visit. (Panel A) The preoperative scan indicated obvious epimacular membrane traction, ellipsoid line disruption (white triangle) and thin bridge of tissue in the inner retina layer (white arrow). (Panel B) A full-thickness macular hole (MH) was discovered one week after surgery with a diameter of 151 μm. (Panel C) The MH was enlarged, and the ILM flap was still covering the surface of the MH one month after surgery. (Panel D) The MH closed automatically about four months after the surgery without further surgical treatment. (E-H) Forty-four-year-old female with an axial length of 27.70 mm had received fovea-sparing ILM peeling without inverted ILM flap. The postoperative BCVA decreased from 0.60 logMAR to 1.85 logMAR. (Panel E) The preoperative scan showed a serve ellipsoid line disruption (white triangle). (Panel F) The degree of foveoschisis was relieved at four days after surgery. (Panel G) A full-thickness MH with diameter of 425 μm was discovered ten days after surgery. (Panel H) The MH was closed with ILM tissue insertion three months after the second surgery, which including ILM inserted, inverted ILM flap and air tamponade three months after the primary surgery
