Trends and characteristics of ocular exposures related to e-cigarettes and e-liquids reported to Poison Control Centers in the United States, 2010–2019.

Ocular injuries and unintended exposures involving electronic nicotine delivery systems (ENDS), also known as e-cigarettes, have been reported. However, trends and characteristics of ENDS-related ocular exposures at the population level are not well documented. This study was designed to describe trends and characteristics of ENDS-related ocular exposure cases reported to poison control centers (PCCs) in the U.S. We computed descriptive statistics of ENDS-related ocular exposure cases reported to PCCs between January 1, 2010 and December 31, 2019, including number of cases per year and the distribution of characteristics of those cases. We also summarized case narrative review findings. A total of 1,393 ENDS-related ocular exposure cases were reported to PCCs during the study period. Overall number of cases increased from two in 2010 to a peak of 389 in 2014, followed by a steady decline in 2015–2018. Of the 1,393 cases, 42.5% occurred among individuals aged 25 years and older; 20.4 and 17.7% occurred among young adults aged 18–24 years and children younger than five years, respectively. Nearly one quarter (23.8%) of the individuals experiencing ocular exposure sought or were recommended to seek medical attention. Case narrative review found that 59 of 127 (46.5%) cases were due, at least in part, to incorrect use or handling of the products. Our study shows that more than 1,000 ENDS-related ocular exposure cases were reported to PCCs during the study period. Many of these cases involved young children; nearly half were due, at least in part, to incorrect use or handling of the products. Future efforts to prevent these exposures may focus on improving the awareness of the potential harmful effects of ENDS products and the importance of appropriate handling of ENDS products. Health care professionals may play an important role in educating patients and improving surveillance of ENDS-related ocular exposure cases. [ABSTRACT FROM AUTHOR]
