Analysis Of Wound-related Factors And Prognosis For Ocular Trauma In 446 Inpatients

Objective: The thesis is to explore the high risk factors of ocular trauma and the relevant factors of prognosis through contrast and data analysis of various factors that may cause ocular trauma. It is to provide reliable information for the prevention of ocular trauma.Method: The research adopted the method of statistical analysis. It analyzed the data of 446 ocular trauma inpatients of two class A of categary three hospitals in Chang Chun from 2008 to 2009. The content included their general conditions, differences in eyes, sources, injury causes, environment and time, treatment time, eyesight on admission, eyesight when left the hospital, injury nature and therapy costs.Results: The young or middle-aged males were domain in 446 ocular trauma inpatients. The ratio of male to female was about 5.4:1 which was the highest among the 40-50-year-old group of people. The average age of the patients was 34.6 and the high risk age is 30-50. Most patients came from rural areas, among whom were mainly workers, peasants and students. The one-eye injury cases were obviously more than two-eye injury ones and the left-eye injury cases were more than the right-eye injury ones. The causes were mainly sharp instrument injury, followed by the fight injury and blunt injury. These incidents often took place in public places, factories and households. The mechanical injury ranked the highest, including a maximum of perforating injury of eyeball, followed by orbital contusion. When leaving the hospital, the patients whose eyesight was improved account for 42.51%. It was shown that May and June each year and 9-11 a.m. each day were the time when incidences often took place. The number of the people who went to see a doctor within 24 hours after the injury accounted for 63.45%. The contrast of relevant factors shows us: the environment was significantly different from such factors as gender, age, occupation, source; the causes of injuries were significantly different from such factors as occupation, source; there was no significant difference between gender and age; the characteristic of injury was significantly different from such factors as gender, occupation, environment, treatment time and eyesight. The major factors affecting eyesight after therapy include: occupation, injury causes, treatment time, injury nature and the degree of visual impairment when the patients were in hospital. Among the factors, treatment time, workers, drivers, fight injury and foreign body injury were the separate protection factors of eyesight variation compared with other ones. While the eyesight on admission and orbital contusion is the high risk factors. The therapy costs of orbital contusion ranks the highest, followed by foreign body injury and perforating injury of eyeball.Conclusion:1.The study of the distribution of 446 cases shows that the patients were mainly male, young or middle-aged, workers, peasants and students, most of whom were from rural areas. The mechanical injury ranked the highest, of which the open eye injury especially perforating injury of eyeball was in the majority. Single-eye injuries are relatively more than the others. Sharp instrument injury, fight injury and blunt injury were common in this study. These often took place in public places, factories and households. May and June were the two months of high incidence.2. The study shows that the following cases of ocular trauma occur more often: the penetrating injury and foreign body injury of men in workplace; the orbital trauma of women in families; the foreign body eye injuries of workers in workplace; the penetrating injury of children and students caused by sharp instrument; the trauma of farmers, the jobless and other people in public places.3. The penetrating eye injury, blunt injury, foreign body eye injury caused serious visual impairment and the patients usually received treatment in time. Orbital contusion caused less serious visual impairment and the patients usually didn't receive treatment in time. The blindness rate is up to 51.56% when the patients are admitted to hospital and the rate is 37.56% when the patients left the hospital. It can be seen that ocular trauma is the main reason leading to monocular blindness. Since it has terrible effects on both society and family, we should pay more attention to it.4. The study shows that the factors which affect the prognosis include occupation, injury causes, treatment time, injury nature and the degree of visual impairment on admission. Among the factors, treatment time, workers, drivers, fight injury and foreign body injury were the separate protection factors of eyesight variation. While the eyesight on admission and orbital contusion is the high risk factors. 5. The study shows that the majority of ocular trauma is preventable and treatable. It is necessary to suggest the relevant departments in the region to conduct a large-scale epidemiological investigation and carry out effective prevention interventions.
