title: Glaucoma after open globe injury at a tertiary care university hospital in Central Saudi Arabia. Cumulative incidence and risk factors.
abstract: OBJECTIVE
  To investigate the incidence and risk factors of glaucoma after open globe injury (OGI).
  
  
  METHODS
  The medical records of all patients admitted with the diagnosis of OGI at the Department of Ophthalmology, King Abdulaziz University Hospital, Riyadh, Kingdom of Saudi Arabia and had undergone primary repair from January 1996 to December 2011 were retrospectively reviewed.
  
  
  RESULTS
  For the 15-year study period, 775 patients who underwent repair of an OGI were identified. The overall risk of post-traumatic glaucoma was 5.3% (41/775) with a mean +/- SD follow-up period of 12+/-6.5 months. Univariate analysis revealed that Zone II injury (p=0.027), penetrating ocular injury (p=0.0008), lens injury (p=0.011), vitreous hemorrhage (p=0.002), and presence of intraocular foreign body (p<0.0001) were significantly associated with glaucoma. Age of more than 18 years was critical (p=0.054). Following logistic regression, penetrating ocular injury (p=0.019), lens injury (p=0.002), and vitreous hemorrhage were significant (p=0.037).
  
  
  CONCLUSIONS
  Glaucoma after OGI is not uncommon. Zone II injury, penetrating ocular injury, lens injury, presence of vitreous hemorrhage, and presence of an intraocular foreign body were significant risk factors for developing post-traumatic glaucoma.
