Objective To determine the prevalence of ocular trauma and proportion of blindness and visual impairment due to ocular trauma in a rural population in northern China.
Methods The Handan Eye Study is a population-based cross-sectional study surveyed 6830 Chinese people aged 30+ years from 13 randomly selected villages ofYongnianCounty,Handancity, Hebei province in 2006-7. All participants underwent a standardized interview and extensive examinations including ophthalmologic and systemic conditions. A structured questionnaire was used to collect information on ocular trauma.
Results Of the 5837 participants having the questionnaire data, 124 subjects (2.1%, 95% confidence interval [CI], 1.8%-2.5%) gave a history of ocular trauma in either eye, including 19 (0.3%) persons reporting trauma in both eyes. Of those, 28.6% had trauma from a blunt object, 33.3% from a sharp object, and 15.1% from chemical burns, 11.1% from plant. Men were more likely to have an eye injury than women (odds ratio [OR], 3.0 [95% CI, 1.99 –4.52]). After adjusting for age and sex, younger persons had a higher risk of ocular trauma (per year increase in age, OR 0.98, 95%CI 0.96–0.99). In multiple logistic regression models ocular trauma was significantly more frequent among normal tension participants when compared with hypertensive group (hypertensive Versus normotensive, OR, 0.59 [95% CI, 0.39–0.90]) and among participants who had a history of any falls (OR, 2.37 [95% CI, 1.17–4.79]). A significant proportion (n = 29 [27.5%]) of subjects with trauma did not went to sought for treatment. The proportion of unilateral visual impairment and unilateral blindness due to trauma were 10.5% (13 subjects) and 21.0% (26 subjects) respectively. Traumatic cataract was the predominant cause of unilateral visual impairment and unilateral blindness (35.9%), traumatic corneal scars (30.8%), phthisical (12.8%), surgical anophthalmia (10.3%) and traumatic optic atrophy (7.7%) were other common causes of unilateral visual impairment and unilateral blindness defined using BCVA.
Conclusions Our study reports the prevalence of severe ocular trauma among adults 30 years and older in ruralChinaand the high proportion of blindness and visual impairment due to ocular trauma. These findings underscore a pressing need for eye care programs targeting rural population to increase the eye health awareness, while improving the management of eye trauma to the reduce blindness due to trauma. |
