title: Multilayered retinoschisis associated with optic disc pit.
abstract: BACKGROUND
  Recently, optical coherence tomography (OCT) analysis has contributed greatly to the detection of posterior retinoschisis associated with optic disc pits. We report an unusual case of optic disc pit maculopathy.
  
  
  METHODS
  A 37-year-old woman with a multilayered structure of posterior retinoschisis associated with a very small, shallow optic disc pit was treated.
  
  
  METHODS
  The patient came to our clinic after a few weeks of decreased vision in her right eye. Fundus examination showed a shallow macular detachment with a tiny, shallow pit at the temporal edge of the optic disc. OCT revealed an unusual multilayered structure of retinoschisis connected to the optic disc. We performed vitrectomy with induction of the posterior hyaloid separation and gas tamponade. After vitrectomy, OCT showed a marked fluid resolution in the retinoschisis, and the patient's vision improved rapidly.
  
  
  CONCLUSIONS
  The multilayered separation of retinoschisis can be caused by traction of the optic disc with a tiny, shallow pit at the temporal edge of the disc.
