In the 10-year period from 1977 to 1987, lawnmowers have been responsible for approximately 70,000 injuries annually with an estimated 5% (3300) involving the eyes. Hyphema, angle recession, and traumatic retinopathy are especially common forms of lawnmower ocular trauma. A series of 14 cases of lawnmower-induced eye injuries is presented along with demographics of the patient population involved. An analysis of various types of lawnmowers currently in use are also included, and preventive measures are suggested. © 1988, American Academy of Ophthalmology, Inc. All rights reserved.
