Purpose: To report non-operative closure of an idiopathic full thickness macular hole (FTMH) spontaneous secondary to the development of a macular epiretinal membrane (ERM). Observations: A 68-year-old woman, with no relevant medical history, and a 6-month history of decreased visual acuity in her right eye was diagnosed to have an idiopathic FTMH. The patient refused surgery and the FTMH was followed-up for seven years. The spectral domain optical coherent tomography follow-up showed the evolution of the FTMH and its spontaneous closure after development of an ERM. In the presence of an ERM with vitreo-papillary detachment, it is possible that the centripetal forces involved helped bring together the edges of the macular hole resulting in a possible spontaneous closure. Additionally and separately, the presence of an ERM may act as scaffolding for Muller cell migration and consequent macular hole closure. Conclusions and importance: Development of an ERM was followed by non-operative FTMH closure in this specific case. It is important to note, that this is an extraordinary situation in which the patient had a favorable anatomical evolution despite having rejected conventional surgical intervention. Studies aimed at determining the mechanisms and situations in which these cases occur could provide answers that help us make more appropriate decisions. To our knowledge, the present case is the first in the literature to report a spontaneous closure of a FTMH secondary to the appearance and progression of a previously non-existent ERM.
