Amniotic membrane plug to promote chronic post-traumatic macular hole closure

Background and Objective: To assess the efficacy of the amniotic membrane (AM) to close a chronic post-traumatic macular hole (PTMH). Patients and Methods: A patient affected by PTMH derived from a blunt trauma occurring 25 years ago who had never undergone surgery was referred to the authors' clinic. He underwent a pars plana vitrectomy (PPV) with an AM plug implant in the macular hole (MH) and 20% sulfur hexafluoride (SF6) as endotamponade. The patient was positioned face-down for the first 5 postoperative days. Results: Prior to surgery, the MH displayed an internal diameter of 971 μm, and the preoperative best-corrected visual acuity (BCVA) was 20/400 (1.3 logMAR). Optical coherence tomography (OCT) showed a chronic MH with flat margins. Ten days after surgery, BCVA was 20/200 (1 logMAR), and the MH was closed. Three months after surgery, BCVA improved to 20/100 (0.7 logMAR), and the MH remained closed. No adverse events were registered during the follow-up period. Conclusion: AM plug seems to be useful to close chronic PTMH with good BCVA recovery.
