title: Traumatic wound dehiscence after penetrating keratoplasty.
abstract: BACKGROUND
  The aim of this study was to evaluate risks and consequences of traumatic wound dehiscence after penetrating keratoplasty (PK).
  
  
  METHODS
  Data regarding 34 eyes of 34 patients who were treated for traumatic wound dehiscence after PK between 1995 and 2014 were studied. Patient records were reviewed for type and time of insult, corrected distance visual acuity (CDVA), clinical presentation signs, operative method, and outcome.
  
  
  RESULTS
  The interval between PK and trauma ranged from 1 month to 100 months, with median of 14 months. Median age at trauma was 31.5 years (range: 5-81 years). Wound dehiscence occurred at donor-recipient interface in all patients. In 58.8% of patients, extent of dehiscence was ≥6 clock hours. Most frequent type of trauma was blunt trauma by hand/finger (35.2%). Median CDVA before and just after trauma were 0.5 logMAR (range: 0.1-3.0 logMAR) and 3.0 logMAR (range: 0.7-3.0 logMAR), respectively. Wound dehiscence was managed with primary wound closure in all patients. Most frequent additional surgical procedure was anterior vitrectomy (26.4%). Anatomical globe loss occurred in 2 patients. Median CDVA was 0.7 logMAR (range: 0.1-3.0 logMAR) at final visit. Most common complication after primary suturation was graft failure (23.5%). Graft remained clear in 67.6% of patients.
  
  
  CONCLUSIONS
  Traumatic wound dehiscence is one of the potentially devastating postoperative complications that can occur following PK. Prognosis depends on existence and severity of additional anterior/posterior segment damage. In order to prevent this catastrophic condition, patients should be warned against ocular trauma after undergoing PK.
