PURPOSE
Lawn trimmers are widely used to cut the weeds around graves in South Korea, but they can cause ocular injury. We investigate at the emergency room the incidence and the clinical features of ocular trauma induced by lawn trimmers.
METHODS
The authors analyzed 106 patients who visited Konyang University Hospital's emergency room from March 1, 2007, to October 31, 2011, because of ocular trauma caused by a lawn trimmer. Patients were sorted into two groups, severe ocular injury and mild ocular injury.
RESULTS
Over a 5-year period, 106 patients with ocular trauma caused by a lawn trimmer underwent clinical study. Most of the patient (103 patients) were males, and the average age of the patients was 51.75+/-11.66 years. The incidence of ocular trauma peaked in the sixth decade of life. Most injuries occurred between July and September. Severe ocular injury developed in 46.2% of all patients. As age increased, so did the severity of the ocular injury. The impacting object was a small stone in 43.4% of all patients. Nobody wore protective gear. The most common diagnosis were corneal abrasion, followed by intraocular foreign body, corneal laceration, and sclera laceration. Fifty-four patients were followed up, and thirty-six patients of them had severe injury. The most common complication was a traumatic cataract.
CONCLUSION
Ocular trauma induced by a lawn trimmer is more severe than general ocular trauma. We suggest that everyone using a lawn trimmer should wear protective gear and follow safety guidelines.

AbstractAbstract PDF
PURPOSE
Blunt trauma can cause a wide range of ocular injuries. This study was performed to describe the prevalence of severe intraocular injuries (SIOI) and their correlation with the severity of blunt orbital trauma.
METHODS
We retrospectively analyzed 117 eyes of 107 patients with orbital wall fractures who visited the emergency room at Konyang University Hospital from July 2006 to June 2008. Clinical features such as age, sex, causes of injury, revised trauma score (RTS), type of orbital wall fractures were recorded. The patients were divided into two groups: blowout fracture with severe intraocular injuries (SIOI) and blowout fracture without SIOI. We compared the clinical and the injury-related characteristics between two groups and analyzed the SIOS-related factors.
RESULTS
Among the 107 patients (117 eyes) with blowout fractures, 29 (27.1%) patients with 32 eyes (25.6%) had complicated severe intraocular injuries. Retrobulbar hemorrhage (14.5%), hyphema (13.7%), traumatic optic nerve injury (4.3%), and sustained loss of visual acuity (4.3%) were the most common SIOI disorders. A logistic regression analysis revealed that loss of visual acuity (odds ratio = 4.75) and eyeball motility disorder (odds ratio=7.61) were significantly associated with SIOS.
CONCLUSION
We suggest that blowout fracture patients with loss of visual acuity or eyeball motility disorder are mostly likely to have severe intraocular injuries, so they need an ophthalmologic evaluation immediately.
