The Study Of The Leading Cause And The Prognosis Of 1673 Cases Mechanial Ocular Trauma

OBJECT:To discuss the risk factor of mechanical ocular trauma and the major determinant of visual prognosis of in-patients of the 2^ndXiang Ya Hospital of Central South University from 2002-2006 by statistical analysis and retrospective study.METHOD:This is a retrospective study on 1673 cases obtaining from the in-patients of the 2^ndXiangYa Hospital due to mechanical ocular trauma in recent 5 years.(2002.1.1-2006.12.31)We record and analysis the following details:general state of health,left or right eye,circumstance of injury,cause of injury,whether treated in time,treatment on spot,time to outpatient department,vision of admission,vision of discharge,means of treatment,cost of hospitalization.RESULTS:The incidence of mechanical ocular trauma is increasing in the 2^nd XiangYa Hospital from 2002-2006.Sex distribution:Male 8/9,Female 1/9.Most of patients fall in the group of age between 5-10 and 35-45,and with the highest sex distribution of 15/1 at the age of 15-20.Most of the patients are peasants,laborer and students come from countryside.Most of the 1848 injuried eyeballs in 1673 inpatients were Open wound of eyeball,contund of the eyeball or appendant organ.Injury caused by foreign object is most frequently seen in mechanical ocular injury,and most frequent complications are traumatic cataract or vitreous hemorrhage.Vitrectomy is the treatment most commonly used.Most of patients had a significant visual improvement at the time of discharge (P＜0.05).The leading cause of the ocular trauma comes from blunt injury, followed by sharp instrument injury and explosion injury.Most injury occurs in public,industrial and family occasion.And the trauma occurs most frequently in January and February.The major determinants of the visual prognosis after treatment are summarized as following:cause of the injury(P=0.0002),whether treated within 24 hours(P=0.001), whether treated by operation(P＜0.0001).The highest mean cost is caused by foreign object and the highest total cost comes from contund of the eyeball or appendant organ.CONCLUSION:1)The incidence of mechanical ocular trauma is increasing in the 2^nd XiangYa Hospital from 2002-2006.2)Most of the ocular trauma comes from blunt injury,sharp instrument injury and explosion injury.Mostly occurs in public,industrial and family occasion.And the trauma occurs most frequently in January and February.We consider it to be significant,because Chinese people had a long vacation for Chinese lunar New Year.3)The major determinants of the visual prognosis after treatment are summarized as following:cause of the injury,whether treated within 24 hours,whether treated by operation.
