title: Spontaneous closure of stage IV idiopathic full-thickness macular hole and late reopening as a lamellar macular hole: a case report.
abstract: BACKGROUND
  Spontaneous closure of traumatic macular holes is described as a common event in the peer-reviewed literature. However, the spontaneous closure of stage III and IV full-thickness idiopathic macular holes has been reported in less than 15 cases in the literature, this being an extremely rare event, with their reopening being even more infrequent. We report a case of a spontaneous closure of stage IV idiopathic full-thickness macular hole and late reopening as a lamellar macular hole.
  
  
  METHODS
  A 67-year-old Spanish man was referred to our hospital with a complaint of decreased vision in his right eye and metamorphopsia for approximately 11 months. He did not report any trauma. Diagnosis was based on fundoscopic and optical coherence tomography. They revealed a stage IV full-thickness idiopathic macular hole and a small epiretinal membrane. Three months later the hole spontaneously closed, and two years later we appreciated its reopening as a lamellar macular hole.
  
  
  CONCLUSIONS
  The contraction of the epiretinal membrane could have contributed to cystic spaces and their fusion, subsequently, to the formation of a lamellar macular hole. To the best of our knowledge this is the first report in the literature of a spontaneously closed full-thickness idiopathic macular hole with reopening as a partial thickness macular defect.
