title: Hyphema caused by trauma.
abstract: BACKGROUND
  Diagnosis and in time treatment of traumatic hyphema could prevent the consequent complications such as, intraocular pressure, blood deposition in the cornea, cataract, the optic nerve damage, and reduction of visual acuity, etc. The aim of this study is identifying the prevalence of the traumatic hyphema incidence in the patients referring to the University Hospital of Boo-Ali-Sina in the city of Sari (Northern Iran) in 2009 -2010.
  
  
  METHODS
  In this descriptive cross-sectional study, 28 medical records related to traumatic hyphema were investigated. A checklist was designed to extract the data.
  
  
  RESULTS
  The most frequency of traumatic hyphema was related to male gender 22 (78/6%), 9 (32.1%) cases age 5-14 years, student 12 (42.9%)cases, 14(50%) urban, 10 (35.7%) cases length of stay was 3 days. The traumatic hyphema was most common in summer 11 (39.3%) cases. The majority 15 (53.6%) of subjects were unilateral (left eye). The mode of the trauma was contact with blunt object in 18 (64.2%) subjects. Protocol of treatment in most subjects 23 (82%) was medication and cornea operation in 2 (7.1%) cases. The highest frequency of the time period between the incidence of injury and referring to the hospital in less than 1 hour was reported in 10 (35.7%).
  
  
  CONCLUSIONS
  In the present study, the traumatic hyphema was observed more in male, especially in the young and adolescent and in the students and workers. Therefore the issue of prevention of ocular trauma and instruction about the eye protection is very important.
