title: Inadvertent retention of Descemet Membrane in penetrating keratoplasty.
abstract: OBJECTIVE
  To present a case of inadvertently retained Descemet Membrane (DM).
  
  
  METHODS
  Case report.
  
  
  RESULTS
  A 41-year-old male with previous history of retinal detachment surgery underwent a repeat penetrating keratoplasty; the first graft decompensated secondary to silicone oil. Postoperatively, an inadvertently retained DM was observed forming a physical barrier to the silicone oil.
  
  
  CONCLUSIONS
  Retained DM is a rare complication of penetrating keratoplasty, with only a few cases reported in the literature. This membrane served a protective role from the effects of silicone oil on the donor cornea but later opacified and required surgical intervention.
