Leading causes of consumer product-related ocular trauma have not been well described. To delineate these causes in a nationally representative sample, data collected by the US Consumer Product Safety Commission (USCPSC) were reviewed. Data were obtained from the National Electronic Injury Surveillance System (NEISS), a national probability sample survey conducted by USCPSC that continuously monitors consumer product-related injuries treated in hospital emergency rooms across the United States. These data formulated the product summary report for the calendar year 1991. The sampling frame for the NEISS consisted of hospitals listed on the Center for Health Statistics Master Inventory File stratified geographically by size of hospital and number of emergency-room visits. During the calendar year 1991, there were a nationally estimated 298,852 consumer product-related eye injuries treated in hospital emergency rooms. Appoximately 500 different products were implicated in these injuries, with the leading cause being contact lenses (hard and soft), accounting for an estimated 26,490 emergency-room visits. This is followed by welding equipment (12,771 visits), hair curlers/curling irons (5946 visits), and workshop power grinders (5476 visits). Consumer products account for a sizable number of ocular injuries requiring treatment in hospital emergency rooms. Research on outcomes and prevention strategies of the injuries is warranted.
